U.S. Customs and Border Protection: Trade Facilitation, Enforcement, and Security

Summary
International trade is a critical component of the U.S. economy, with U.S. merchandise imports
amounting to $2.4 trillion and exports to $1.6 trillion in 2014. The efficient flow of legally traded
goods in and out of the United States is thus a vital element of the country’s economic security.
U.S. Customs and Border Protection (CBP), within the Department of Homeland Security (DHS),
is the primary agency charged with monitoring, regulating, and facilitating the flow of goods
through U.S. ports of entry (POEs). CBP’s policies are designed to (1) ensure the smooth flow of
imported cargo through U.S. POEs; (2) enforce trade and customs laws designed to protect U.S.
consumers and business and to collect customs revenue; and (3) enforce import security laws
designed to prevent weapons of mass destruction, illegal drugs, and other contraband from
entering the United States—a complex and difficult mission. Congress has a direct role in
organizing, authorizing, and defining CBP’s international trade functions, as well as appropriating
funding for and conducting oversight of its programs. In the Senate, on May 14, 2015, S. 1269
was incorporated into H.R. 644 (renamed the Trade Facilitation and Trade Enforcement Act of
2015) and subsequently passed by a vote of 78-20. On June 12, 2015, the House passed an
amended version of H.R. 644 by a vote of 240-190. Senate and House leaders have reportedly
committed to resolve the two bill versions in a conference committee.
Laws currently authorizing the trade facilitation and enforcement functions of CBP (as outlined in
the Customs Modernization and Informed Compliance Act, Title VI of P.L. 103-182) emphasize a
balanced relationship between CBP and the trade community based on the principles of “shared
responsibility,” “reasonable care,” and “informed compliance.” Since the 9/11 terrorist attacks of
2001, Congress has placed greater emphasis on import security and CBP’s role in preventing
terrorist attacks at the border. Legislation addressing customs procedures and import security
includes the Homeland Security Act of 2002 (P.L. 107-296), the Security and Accountability for
Every (SAFE) Port Act of 2006 (P.L. 109-347), and the Implementing Recommendations of the
9/11 Commission Act of 2007 (P.L. 110-53).
CBP’s current import strategy emphasizes a risk management approach that segments importers
into higher and lower risk pools and focuses trade enforcement and import security procedures on
higher-risk imports, while expediting lower-risk flows. CBP’s “multi-layered” risk management
approach means that security screening and enforcement occur at multiple points in the import
process, beginning before goods are loaded in foreign ports (pre-entry) and continuing long after
the time goods have been admitted into the United States (post-entry).
How effectively CBP has performed its import policy mission is a matter of some debate. Some
participants in CBP’s “trusted trader” programs argue that the concessions (e.g., expedited
processing; fewer container inspections) CBP provides at the border do not adequately justify the
effort and expense to certify their supply chains. Questions have also been raised about CBP’s
management of trade facilitation, especially the means through which the Automated Commercial
System (ACS) trade data management system is being phased out in favor of the newer
Automated Commercial Environment (ACE). Some critics also assert that CBP has not
adequately fulfilled its trade enforcement role, especially its duties for preventing illegal
transshipments, protecting U.S. intellectual property rights, and collecting duties. Still others
criticize CBP’s performance of its security functions, especially because it does not yet physically
scan 100% of maritime cargo as mandated by the SAFE Port Act of 2006, as amended. In May
2014, DHS Secretary Jeh Johnson extended the deadline for an additional two years.

U.S. Customs and Border Protection: Trade Facilitation, Enforcement, and Security

Introduction
International trade is a critical component of the U.S. economy, with U.S. goods trade amounting
to about $4 trillion in 2014, with merchandise imports of $2.4 trillion and exports of $1.6 trillion
(see Appendix B).1 The efficient flow of legally traded goods in and out of the United States is
thus a vital element of the country’s economic security. While U.S. trade in imports depends on
the smooth flow of legal cargo through U.S. ports of entry (POE), the goal of trade facilitation
often competes with two additional goals: enforcement of U.S. trade laws and import security.
How to strike the appropriate balance among these three goals is a fundamental question at the
heart of U.S. import policies.
Striking the appropriate balance among competing import policy goals is made more difficult due
to the volume and complexity of trade inflows. U.S. Customs and Border Protection (CBP), the
agency charged with managing the import process at the border, admitted about 30.4 million
import entries2 per year through over 300 U.S. POEs, in fiscal year (FY) 2013.3 The largest
volume of imports comes through land (truck and rail) and maritime flows, which together
account for over 25 million shipping containers per year. Air cargo consists mainly of lower
volume, higher value goods.4
This report describes and analyzes CBP’s role in the U.S. import process. (The report does not
cover CBP’s role in the U.S. export control system.) The first section of the report describes the
three overarching goals of U.S. import policy and the tension among them. Second, the report
summarizes recent legislative developments and provides a legislative history of customs laws,
followed by an overview of the U.S. import process as it operates today. Third, the import process
and CBP’s role in it are discussed.
Congress has a direct role in organizing, authorizing, and defining CBP’s international trade
functions, as well as appropriating funding for and conducting oversight of its programs. Thus,
the final section highlights several policy issues that Congress may consider in its oversight role
or as part of customs or trade legislation, including measures seeking to provide additional trade
facilitation benefits to importers and others enrolled in “trusted trader” programs, to improve
enforcement of intellectual property and trade remedy laws, to strengthen cargo scanning
practices, and/or to promote modernization of customs data systems, among other issues.

Overarching Import Policy Goals
U.S. import policy seeks to balance three overarching policy goals. First, import policy promotes
trade facilitation. Trade facilitation refers to efforts to simplify and streamline international trade
procedures to allow for the easier flow of legitimate goods across international boundaries and

CRS calculations for FY2005-FY2013, based on data presented in Table 1. The value of imports in FY2014 was
divided among sea (49%), air (23%), and land (26%) inflows, based on data presented in Table B-1. Although certain
issues raised in this report apply to the import process in general, this report focuses on containerized (as opposed to
bulk) goods, and does not address imports and exports in foreign trade zones. This report also does not address the
Transportation Security Administration’s role in air cargo security, which is discussed in CRS Report RL33512,

thereby to reduce the costs of trade.5 Trade facilitation includes the availability of advanced
customs rulings, transparent and efficient procedures, elimination of “red tape,” clear
information, effective communications, and cooperation between border agencies, among other
provisions.6
Trade facilitation is a priority for CBP and the trade community because trade represents a key
component of the U.S. economy. International trade accounts for about a quarter of the U.S.
economy, with merchandise trade (i.e., cargo) accounting for more than three-quarters of all U.S.
trade flows.7 Most economic research finds that while international trade may impose short-term
costs on certain sectors and industries that compete with imports, in the long run, trade promotes
efficiency, reduces costs to consumers, and increases economic growth due to competitive
advantage.8 With the production of goods increasingly organized into global supply chains, in
which the manufacture and final product assembly often occur in two or more countries,
intermediate components during the manufacturing process are a significant percentage of total
imports and exports in most countries, and a wide variety of U.S. manufacturers depend on the
efficient import and export of these inputs.9
Partly for this reason, trade facilitation has been a priority issue for the United States and its
international partners in organizations such as the World Trade Organization (WTO) and the
World Customs Organization (WCO), and in free trade agreement negotiations (FTAs). Within
the WTO Doha Development Round of multilateral trade negotiations, for example, the United
States has pursued “the shared objective of a rules-based, transparent, and efficient approach to
goods crossing the border.”10 In the WTO, the United States was instrumental in negotiating
binding disciplines on trade facilitation included in the December 2013 multilateral “Bali
Agreement.” The United States and other members of the WCO are encouraging the use of
electronic systems to expedite the clearance of merchandise entries and to ensure effective
customs controls, including the adoption of a “single window” data system through which
multiple cross-border regulatory agencies can clear merchandise entries (see “Interagency
Coordination”).11
There is an inherent tension between efforts to promote efficient trade flows, and a second goal of
U.S. import policy: the enforcement of trade laws designed to protect U.S. consumers and
business against illegal imports and to collect customs revenue. In general, U.S. trade laws seek
to protect U.S. consumers by enforcing health and safety standards, and to protect U.S. businesses
by enforcing patent, trademark, and copyright laws and by collecting anti-dumping and
countervailing duties (AD/CVD).12 Trade enforcement policies also govern the collection of

tariffs, fees, and taxes; CBP generated more than $36 billion in revenue in FY2013, including
more than $31 billion in customs duties.13
The third overarching goal of U.S. import policy is import security, or preventing the entry of
chemical, biological, radiological, and nuclear (CBRN) weapons and related material; illegal
drugs; and other contraband. While customs agencies have always played a role in protecting
public safety, including through narcotics enforcement in particular, the terrorist attacks of
September 11, 2001 (9/11), caused many Americans to place even greater emphasis on
transportation and port security. Thus, security measures enacted after 9/11 placed additional
responsibilities on customs officials to pro-actively prevent weapons of mass destruction and
other threats to the homeland from entering the United States and have made import security a
central feature of U.S. trade policy (see “Major Post-9/11 Import Security Legislation”). Import
security also has become an important feature of international efforts, and the United States and
its partners in the WCO have adopted new security protocols for tracking, inspecting, and
screening containerized imports and exports.14
Trade facilitation is in tension with trade enforcement and import security because trade
facilitation involves promoting faster and more efficient trade flows, while trade enforcement and
import security involve identifying and preventing illegal flows—tasks that often involve slower
cargo flows and reduced efficiency for the importer. These competing pressures make the
implementation of import policy a complex and difficult task, which CBP addresses through a
process of risk management, as described below (see “The Import Process”).
Many policy questions with respect to the import process concern how Congress and CBP
balance these three goals. Some U.S. importers and some in Congress have criticized CBP for
neglecting trade facilitation in favor of import security and trade enforcement. For example, some
in the trade community view the paperwork and additional reporting requirements imposed on
U.S. importers as overly burdensome, and they assert that these requirements run counter to U.S.
interests by threatening America’s economic security.15 Others argue that infrastructure issues,
scanning, and inspections at land ports of entry result in unacceptably long and unpredictable
border wait times. Delays have been described as particularly onerous at the U.S.-Mexico border,
where trade has increased more than sixfold since the North American Free Trade Agreement
(NAFTA) was implemented in 1994.16 Several studies have estimated the economic consequences
of border crossing delays, including a 2008 draft report by the Department of Commerce that
estimated that crossing delays at the U.S.-Mexico border resulted in $5.8 billion in lost economic
output, $1.4 billion in lost wages, 26,000 lost jobs, and $600 million in lost tax revenues—and
would result in losses twice this size by 2017.17 A review of nine additional studies concluded that

“one message comes through quite clearly—long and unpredictable wait times at the POEs are
costing the United States and Mexican economies many billions of dollars each year.”18
At the same time, others in Congress and in the trade community assert that the United States
may remain vulnerable to a terrorist attack against a port of entry—with potentially catastrophic
results—and that CBP should place greater emphasis on import security, even if the economic
costs are high. Some Members have expressed frustration, for example, that the great majority of
cargo containers are not scanned or physically inspected prior to arrival at a U.S. port.19 Similarly,
some manufacturers have alleged that CBP has not adequately investigated allegations of duty
evasion, product mislabeling, fraudulent country of origin declarations, or deliberate
misclassification of shipments;20 and some assert that their intellectual property rights (IPR) are
being violated by ever growing imports of counterfeit goods, and that CBP efforts in
collaboration with the private sector in identifying and enforcing IPR violations have been
inadequate.21 In short, how Congress and CBP balance trade facilitation, trade law enforcement,
and import security has important implications for homeland security, public safety, and virtually
every sector of the U.S. economy. To varying degrees, this tension underlies most aspects of U.S.
import policymaking.

Legislation in the 114th Congress
Several bills have been introduced in the 114th Congress to reauthorize CBP’s customs-related
activities, including S. 1269, the Trade Facilitation and Trade Enforcement Act of 2015 (Hatch;
introduced May 11, 2015); related bill H.R. 1907 (Tiberi; introduced April 21, 2015); and H.R.
1916 (Levin; introduced April 21, 2015). S. 1269 was reported by the Senate Finance Committee
on May 13, 2015; and H.R. 1907 was marked up and ordered reported by the House Committee
on Ways and Means on April 23, 2015.
In the Senate, on May 14, 2015, the text of S. 1269 was incorporated into H.R. 644 (which was
renamed the Trade Facilitation and Trade Enforcement Act of 2015) and subsequently passed by a
vote of 78-20. On June 12, 2015, the House passed an amended version of H.R. 644 by a vote of
240-190. In a joint statement released June 17, 2015, Senate Majority Leader Mitch McConnell
and House Speaker John Boehner stated their intent “to have a conference on the customs bill and
complete that in a timely manner so that the President can sign it into law.”22

U.S. Customs and Border Protection: Trade Facilitation, Enforcement, and Security

Title I of the House and Senate versions of H.R. 644 would require CBP to, among other things,
work with the private sector and other federal agencies to ensure that all CBP partnership
programs provide meaningful trade benefits to program participants; require CBP to establish key
performance measures on modification; carry out facilitation and trade enforcement functions;
require CBP and Immigration and Customs Enforcement (ICE) to establish joint educational
seminars (with private sector input authorized) for enforcement personnel at POEs; and require
CBP and ICE, in consultation with federal agencies, other law enforcement agencies,
international organizations, and other interested parties, to develop and report to Congress on a
biennial joint strategic plan for trade facilitation and enforcement.
Title I would also authorize existing CBP programs, including customs modernization efforts
such as the Automated Commercial Environment (ACE) and the International Trade Data System
(ITDS), the Commercial Customs Advisory Committee (COAC), the Centers of Excellence and
Expertise (CEEs), and targeting and analysis groups to focus on each of CBP’s Priority Trade
Issues (PTIs). The Government Accountability Office (GAO) and CBP would also be required to
report on CBP improvements in areas including trade enforcement, tracking merchandise in-bond,
and drawback simplification. In Section 111, the Senate version would authorize a Commercial
Targeting Division (CTG) and National Targeting and Analysis Groups (NTAGS) to target
priority trade issues (PTIs). The CTG would establish methodologies for assessing import risk
and issuing Trade Alerts to port directors. Section 111 of the House version would authorize the
National Targeting Center to perform similar functions. Both versions would allow a port director
to determine not to conduct further inspections for certain reasons, provided that other Customs
authorities are notified. Additionally, Title I of the House and Senate versions of H.R. 644 would
require CBP to strengthen internal controls, in part, by developing criteria for assigning importerof-record identification numbers; and would provide CBP with the authority to strengthen
enforcement controls over new importers, including ensuring collection of duties, fees, and
penalties through risk-based bonding. The House-passed version would also require CBP to
collect additional information on “nonresident importers” and would require customs brokers to
collect information on the identity of importers.
The House-passed version of H.R. 644 would also require CBP to establish priority trade issues
(PTIs), including Agriculture, antidumping and countervailing duties (AD/CVD), Import Safety,
Intellectual Property (IPR), Textiles and Wearing Apparel, and Preference Programs. Additionally,
for purposes of the Title, the term “appropriate congressional committees” is specifically
identified as the Committee on Finance and the Committee on Homeland Security and
Governmental Affairs of the Senate; and the Committee on Ways and Means and the Committee
on Homeland Security of the House of Representatives.
Title II of both versions address import health and safety. Title II would establish an interagency
import safety working group, chaired by the Secretary of Homeland Security. The group would be
responsible for developing a joint import safety rapid response plan to establish protocols and
practices that CBP, in conjunction with other federal, state and local authorities, must use when
responding to cargo that poses a threat to the health or safety of U.S. consumers. Title II also
requires joint exercises with these entities and training for CBP port personnel in enforcement of
import health and safety laws.
Title III of both versions of H.R. 644 addresses intellectual property rights (IPR) enforcement.
First, Title III would amend customs laws to authorize and direct CBP (except in cases that would
compromise an ongoing law enforcement or national security investigation) to share information
with rights holders so that they could help to quickly identify whether a product entering the
United States at a POE is in violation of a copyright or trademark. Second, CBP would be
authorized to seize merchandise if it is found to be in circumvention of IPR laws, and would

require CBP to notify an injured right holder if they are included on an annually revised, CBPmaintained list. Third, the Secretary of DHS is directed to enforce copyrights on goods for which
the owner has submitted a copyright application in the same manner as if the copyright were
already registered. Title III would also establish a National Intellectual Property Rights
Coordination Center within CBP.
Title IV of S. 1269, and H.R. 1907, and Title V of H.R. 1916, address antidumping (AD) and
countervailing duty (CVD) evasion. One major difference between the Senate and House versions
is that even though both bills would require the investigation of allegations of AD and CVD
evasion within specific deadlines and requirements, the Senate version would require CBP to
investigate the allegations, while the House version would grant the Department of Commerce
authority to carry out investigations.23 H.R. 1916 would assign primary investigative duties of
AD/CVD evasion to CBP.
Also related to AD/CVD laws, the House version would establish a Trade Remedy Law
Enforcement Division in CBP, direct CBP to identify evasion, authorize increased data sharing
between CBP, the Department of Commerce, and the U.S. International Trade Commission for
enforcement actions against evasion, and direct CBP to enter into agreements with customs
officials in foreign countries to increase cooperation in combatting evasion The House version
would also require CBP to assign sufficient personnel to prevent and investigate evasion, require
CBP to submit an annual report to Congress detailing evasion policies and activities, terminate
the ability of new shippers to post bonds during new shipper AD/CVD reviews, and require the
Government Accountability Office (GAO) to submit a report to Congress on the effectiveness of
CBP efforts in investigating and preventing AD/CVD duty evasion.
Title V of both versions of H.R. 644 seeks to amend AD and CVD laws, in part, by clarifying and
expanding the methods that the International Trade Administration of the Department of
Commerce (ITA) and the U.S. International Trade Administration (USITC) may use to make
determinations in AD/CVD investigations. For example, Title V would clarify that the ITA, in
cases in which an exporter, manufacturer or producer of the targeted merchandise fails to
cooperate by providing information needed to calculate the duty rate, that the highest applicable
dumping or subsidy rate may be used. The amendment would also clarify and expand the
calculation methods that the ITA may use to calculate AD/CVD rates if there are particular market
situations that may distort prices or costs. Title V would also clarify the authority of the ITA to
limit the number of foreign exporters, manufacturers, or producers for which it calculates
individual duty rates24 if it finds that an investigation is unduly burdensome due to the complexity
of the issues or information presented, among other factors.
With regard to the USITC’s injury phase of AD/CVD investigations, Title V would amend the
definition of “material injury” to provide that a negative determination of material injury may not
be found solely on the basis of domestic industry profitability or recently improved performance.
The section would further expand the criteria that the USITC must use to evaluate the impact of
competing imports to include the effects of “actual and potential decline in output, sales, market
share, gross profits, operating profits, net profits, ability to service debt, productivity, return on
investment, return on assets, and utilization of capacity.” Title V would also revise the “captive
23

Antidumping (AD) and countervailing duty (CVD) laws are found in Title VII of the Tariff Act of 1930 (19 U.S.C.
1671-1677n). The International Trade Administration of the Department of Commerce (the administering authority in
the statute) investigates the existence and amount of dumping or subsidies, and the U.S. International Trade
Commission investigates material injury with respect to the U.S. industry petitioners.
24
Foreign exporters, producer, and manufacturers often request that their individual U.S. sales be calculated because
they could receive a lower duty rate than the overall AD/CVD rate.

production test” that the USITC must use to assess injury if the targeted product is a component
used in a downstream finished good.25
Title V of both bill versions would also address additional trade enforcement priorities by
requiring the Administration, in close consultation with Congress, to identify these priorities and
to more regularly consult with Congress on enforcement strategies. The Administration would be
directed to address trade enforcement issues that, if eliminated, would have the most impact on
positive U.S. economic growth. The enforcement provisions in these bills would also authorize
the Administration to reinstate the suspension of concessions under Article 22 of the WTO
dispute settlement agreement under certain conditions. The bills would also require the USITC to
provide an Internet-based database to provide information on the volume and value of imports;
and would require the Department of Commerce to provide reports on quarterly changes in the
volume and value of imports.
Title VI of the Senate bill would also establish a Trade Enforcement Trust Fund to be used by the
USTR and other agencies to enforce U.S. trade agreements and trade rights under the WTO and
U.S. free trade agreements (FTAs). The trust fund could also be used for trade capacity building
efforts. Title VI of the Senate version of H.R. 644 would also require CBP and ICE to institute
certain measures to stop illegal honey transshipment; and require that the two agencies train and
employ sufficient personnel to detect, identify, and seize cultural property, archeological or
ethnological materials, and other fish, wildlife or plants that violate U.S. laws. Title VI would also
codify the establishment of the Interagency Trade Enforcement Center (ITEC).26
Regarding IPR enforcement, the Senate version would add countries that deny adequate
protection of trade secrets to the USTR’s priority watch list, and require the USTR to develop an
action plan for each country that has been on the list for at least one year. S. 1269 would also
establish at USTR a Chief Innovation and Intellectual Property Negotiator with the rank of
Deputy USTR.
Title VII of the Senate version addresses issues regarding currency undervaluation. Among other
things, Title VII would require the ITA to investigate alleged currency undervaluation in
AD/CVD investigations and would provide a method for calculating the amount of
undervaluation. The bill would also require the Administration to actively engage with those
countries found to manipulate exchange rates in order to urge implementation of monetary
policies that would address the issue. The House version would provide for engagement with
other countries on currency undervaluation, but contains no enforcement provisions. Both bills
would also establish an Advisory Committee on Exchange Rate Policy to advise the Treasury
Secretary on the impact of international exchange rates on the policies of the United States.
Title VIII of the Senate version would provide a process for Congress, in conjunction with the
USITC, to receive and consider a miscellaneous trade bill (MTB) containing proposed duty
suspensions and reductions in 2015 and 2018. The process would require Congress to post on the
Internet a process for submission and consideration of proposed duty suspensions for possible
inclusion in the MTB, and also require the USITC to publish in the Federal Register and on the
Internet a notice requesting MTB submissions from the public.27

U.S. Customs and Border Protection: Trade Facilitation, Enforcement, and Security

Title IX of the House and Senate versions of H.R. 644 address miscellaneous customs provisions.
All three bills would raise the de minimis value (currently $200) for unaccompanied cargo to
$800.28 The bills would also require DHS to consult with Congress no later than 30 days after
proposing and 30 days prior to finalizing, any DHS policies, initiatives, or actions that would
have a major impact on trade and customs revenue functions. Other provisions include adding
committing or conspiring to commit an act of terrorism to the list of offenses that are grounds for
removal of a customs broker’s license, amending Harmonized Tariff Schedule chapter 98 to
reduce the record-keeping burden on U.S. goods entering without improvement abroad, and
allowing for the subtraction of the value of U.S. components assembled in goods that are
exported and returned after being improved abroad. Miscellaneous provisions also include
making bulk cargo residue exempt from duty and implementing drawback simplification. All
three bills would eliminate the “consumptive demand” exception to the prohibition on
importation of goods made with convict, forced, or indentured labor.29 The Senate version of H.R.
644 would also provide offsets, in Title X, for the bill by temporarily extending an increased
customs user fee, among other things.

Legislative History of U.S. Customs and Trade
Facilitation, Enforcement, and Import Security
Policies
The U.S. Customs Service (USCS),30 the agency historically responsible for trade facilitation and
enforcement, was established by an act of Congress on July 31, 1789 (1 Stat. 29), and on
September 2, 1789, was placed under the Secretary of the Treasury.31 At that time, the primary
role of the service was to collect U.S. customs tariffs, which were the major revenue source for
the U.S. government until the federal income tax was established in 1913. Key laws establishing
and authorizing the trade functions of the USCS included provisions in the Tariff Act of 1930,32
the Customs Simplification Act of 1953,33 and the Reorganization Plan of 1965.34
More recent customs legislation can be categorized into two components. The first is focused on
the Customs Service’s traditional role of trade facilitation and enforcement, and the second,
which emerged following the 9/11 terrorist attacks, has focused on the issue of import security.
The Homeland Security Act (P.L. 107-296) placed all or parts of 22 different federal departments
and agencies, including the Customs Service, into the Department of Homeland Security (DHS).35
28

The de minimis value level (19 U.S.C. 1321, as amended), is the value threshold below which unaccompanied
shipments may enter U.S. commerce without the need for formal entry procedures or payment of customs duties.
29
Section 307 of the Tariff Act of 1930 (19 U.S.C. 1307), as amended, prohibits the importation of goods made by
convict labor, forced labor, child labor, and indentured labor. The law, however, excludes products that “are not mined,
produced, or manufactured in such quantities in the United States as to meet the consumptive demands of the United
States.
30
In this report, the U.S. Customs Service or USCS is used to refer to the legacy customs agency (before the Homeland
Security Act of 2002 and the subsequent reorganization modification plan changed the name of the agency). When
referring to legislation after 2002, Customs and Border Protection, or CBP, is used.

U.S. Customs and Border Protection: Trade Facilitation, Enforcement, and Security

DHS’s bureau of Customs and Border Protection (CBP) has been the lead agency facilitating,
enforcing, and securing trade flows since 2003.

Major Trade Facilitation and Enforcement Legislation
The last time that the then-USCS’s trade functions were fundamentally reorganized was in 1993,
in Title VI of the North American Free Trade Agreement Implementation Act (P.L. 103-182), also
known as the Customs Modernization and Informed Compliance Act, or “Mod Act.” Other major
legislation addressing these functions was Title IV of the Security and Accountability For Every
(SAFE) Port Act of 2006 (P.L. 109-347) that addressed trade facilitation and enforcement by
reorganizing DHS’s trade functions, requiring increased interaction with the trade community,
and providing for greater congressional oversight.

The “Mod Act” of 1993 (Title VI of P.L. 103-182)
The Mod Act, implemented on December 8, 1993, amended many sections of the Tariff Act of
1930 that applied to USCS’s role in trade enforcement. The law was the culmination of a multiyear effort among Congress, the USCS, and the Joint Industry Group (a coalition of private-sector
firms involved in international trade), to develop legislation on Customs modernization.36 While
the main purpose of the law was to streamline, automate, and modernize USCS’s commercial
operations, the law was also intended to improve compliance with U.S. customs laws, and to
provide safeguards, uniformity, and due process rights for importers.37
The Mod Act addressed the tension between trade facilitation and trade enforcement by replacing
the historical “agency-centric” model of trade enforcement with a “shared responsibility”
approach.38 Thus, whereas USCS previously had monitored imports and determined the level of
customs duties owed by each importer, under the shared responsibility approach USCS (now
CBP) is required to inform importers of their rights and responsibilities under the customs
regulations and related laws; and importers of record are required to be aware of their legal
obligations and to make their own duty determinations through the concept of “informed
compliance.”39 Importers are also required to exercise “reasonable care” when classifying and
determining the value of imported merchandise. If importers have questions about the country of

38
The previous model employed by USCS resembled utility companies’ billing model, which measures usage and
sends customers a statement; while the current model resembles tax collection by the Internal Revenue Service, which
requires businesses and individuals to estimate their own tax liabilities.
39
NAFTA Report, p. 106. In meeting the “reasonable care” standard, House lawmakers suggested that importers
consider using assistance when bringing products into the United States. These aids could include seeking advance
rulings from Customs, consulting with a customs broker or trade attorney, using in-house employees with a knowledge
of customs laws, or obtaining analyses from accredited labs (NAFTA Report, p. 120).

origin, classification, or valuation of merchandise, they may apply to CBP for a binding
determination (known as a customs ruling) prior to importation.40
The Mod Act placed a greater administrative burden on the importer, and shifted USCS’s focus to
the collection of data and post-entry enforcement (i.e., audits) to ensure that all legal requirements
have been met.41 By reducing USCS’s role in duty determination, the act freed up agency assets
to modernize the import process and improve post-entry enforcement.42 Private industry
stakeholders accepted these increased responsibilities because the law also provided for a quicker
and more transparent import process through streamlined and automated customs operations.

Title IV of the Security and Accountability for Every (SAFE) Port Act of 2006
(P.L. 109-347)
Title IV of the SAFE Port Act addressed the organization, management, and oversight of CBP
enforcement functions. Title IV required DHS to designate a senior official to ensure the
coordination of the trade and customs revenue functions in DHS and with other federal
departments and agencies; and that CBP’s trade functions were not diminished and kept pace with
the level of trade entering the United States.
Title IV also required additional consultation with representatives of the business community,
including CPB’s Commercial Operations Advisory Committee (COAC) on DHS policies and
actions that could have significant impact on international trade and customs revenue functions;
and established an Office of International Trade (OIT) within CBP; required DHS, the U.S. Trade
Representative (USTR) to work through the World Trade Organization (WTO), the World
Customs Organization (WCO), and other international organizations to align customs
requirements to the extent possible to facilitate the efficient flow of international trade.
Title IV also authorized the establishment of the International Trade Data System (ITDS) as part
of the Automated Commercial Environment (ACE), CBP’s interactive customs data management
system. ITDS is an intergovernmental project to coordinate and standardize the collection of trade
enforcement data by creating a single portal for the collection and distribution of import and
export data to be used by all 48 federal government agencies that play a role in trade enforcement.
The section required all federal agencies involved in trade enforcement to participate in the ITDS.

Major Post-9/11 Import Security Legislation
While previous customs legislation focused on the tension between trade facilitation and
enforcement, the 9/11 attacks focused America’s attention on homeland security. With the attacks
having been executed by foreign nationals traveling on commercial aircraft, an immediate priority
was to reorganize existing law enforcement resources related to immigration, transportation,
trade, and border security into a new federal Department of Homeland Security (DHS). At least
six laws enacted between 2002 and 2007 included provisions related to the trade process and
made import security a central feature of U.S. trade policy.

U.S. Customs and Border Protection: Trade Facilitation, Enforcement, and Security

Trade Act of 2002 (P.L. 107-210)
Customs reauthorization legislation in the Trade Act of 2002 (Title III of P.L. 107-210, the
Customs Border Security Act of 2002) authorized appropriations for a number of noncommercial
and commercial CBP programs as well as CBP’s air and marine interdiction program. Funds were
also authorized to be appropriated for the Automated Commercial Environment (ACE; see “PreEntry: Advanced Cargo Screening, Scanning, and Inspections”), for equipment and programs for
drug enforcement, and for the detection of terrorists and illicit narcotics along the U.S borders
with Mexico and Canada, and in Florida and Gulf Coast seaports.
The Trade Act also included one of the most significant additions to the customs clearance
process since 9/11: a requirement that importers and exporters submit advance cargo manifest
information prior to cargo arriving at a U.S. port of entry (POE). The law authorized the
Secretary of the Treasury to publish regulations requiring the submission of this information, and
directed the Secretary to consult with a broad range of import and export stakeholders and to base
the regulations on the Secretary’s determination of what is “reasonably necessary to ensure
aviation, maritime, and surface transportation safety and security.”43 CBP uses this advance cargo
information to conduct risk-based targeting through the Automated Targeting System (ATS; see
“Automated Targeting System”).

Maritime Transportation Security Act of 2002 (P.L. 107-295)
The Maritime Transportation Security Act of 2002 (MTSA, P.L. 107-295) expanded DHS’s
authority under the Trade Act of 2002 to collect and share advance cargo data, and took several
steps to strengthen port security.44 Section 102 of the MTSA established a new chapter of the U.S.
Code (46 U.S.C. 701) to establish DHS’s overall role in port security. Among other things, the
law required DHS to assess vessel and port security and to develop national and regional
maritime transportation security plans,45 required certain ports and vessels to develop security and
incident response plans to be approved by DHS,46 and established a Department of Transportation
grant program to help ports implement their security plans.47
The MTSA also established new security requirements for U.S. and foreign ports and for ships
operating in U.S. waters. Within the United States, the law required DHS to establish regulations
to prevent individuals from entering secure areas of vessels or ports unless the individuals hold
security cards. The port security cards are known as Transportation Worker Identity Credential
(TWIC) cards, and are administered by the Transportation Security Administration (TSA) along
with the U.S. Coast Guard.48 With respect to foreign ports (where Congress has no direct
authority), the law required DHS to assess port security at foreign ports and to notify foreign
ports if they are found to lack appropriate counter-terrorism measures.49 DHS is authorized to

restrict the entry of vessels arriving from foreign ports that fail to maintain effective counterterrorism measures.50 With respect to ships and other vessels operating in U.S. waters, the law
required that certain vessels be equipped with an automatic identification system while operating
in U.S. waters, and that DHS also develop and implement a long-range automated vessel tracking
system for certain vessels.51

Homeland Security Act of 2002 (P.L. 107-296)
The Homeland Security Act of 2002 (HSA, P.L. 107-296) created a framework for the transfer of
all or part of 22 different federal departments into the Department of Homeland Security (DHS),
including the USCS and the U.S. Coast Guard.52
Title IV of the act created within DHS a Directorate of Homeland Security headed by the Under
Secretary for Border and Transportation Security.53 The directorate was given responsibility for
preventing the entry of terrorists and the instruments of terrorism into the United States, and for
ensuring the speedy, orderly, and efficient flow of lawful traffic and commerce, among other
things. Title IV also established the U.S. Customs Service and the office of the Commissioner of
Customs within DHS.54 The act specified that certain customs revenue functions would be
retained by the Secretary of the Treasury, who may delegate the authority to the Secretary of
Homeland Security.55 Although the customs inspection and enforcement authority of the former
USCS were transferred to CBP, Section 412(b) of the HSA mandated that DHS could not
“consolidate, discontinue, or diminish” the trade and customs revenue functions of the USCS, or
reduce staffing levels or the resources attributable to these functions.56
The HSA directed the President, no later than 60 days after enactment of the act, to transmit to the
appropriate congressional committees a reorganization plan for the transfer of agencies,
personnel, assets, and obligations to the new Department of Homeland Security.57 The President
submitted an initial plan on November 25, 2002,58 and modified the plan shortly thereafter
following consultation with then Secretary of Homeland Security designate Tom Ridge.59 In the
modification plan, the USCS was renamed the Bureau of Customs and Border Protection (CBP),

Coast Guard and Maritime Transportation Act of 2004 (P.L. 108-293)
The Coast Guard and Maritime Transportation Act of 2004 (P.L. 108-293) contained a number of
maritime security provisions that amended the MTSA. Title VIII of the law added security
requirements to the import process provisions, including amendments to certain long-range vessel
tracking system requirements.61 DHS was also required to submit a plan for implementation of a
maritime intelligence system (previously authorized in the MTSA) to incorporate information on
vessel movements and assign incoming vessels a terrorism risk rating.62
Section 808 of the law required the Department of Transportation to “conduct investigations, fund
pilot programs, and award grants” to examine and develop certain equipment to enhance the
investigative ability of CBP, including equipment to accurately detect nuclear, chemical, or
biological materials; and tags and seals equipped with sensors that are able to track marine
containers throughout their supply chains and to detect hazardous and radioactive materials
within containers.63
The law also required DHS to report on several cargo import security issues, including the costs
to the government of vessel and container inspections, plans for implementing secure systems of
transportation, progress on the installation of radiation detectors at all major U.S. seaports, the
willingness of foreign seaports to utilize non-intrusive inspection (NII) techniques to inspect
cargo bound for the United States, and evaluation of the existing cargo inspection targeting
system for international intermodal cargo containers.64

recommendations to guard against future attacks. The report expressed concern that the United
States lacked “a forward-looking strategic plan” that devoted adequate attention to maritime and
surface transportation.65

U.S. Customs and Border Protection: Trade Facilitation, Enforcement, and Security

Act of 2007 (The 9/11 Act, P.L. 110-53). Title I of the SAFE Port Act focused on port security.
The act updated several deadlines from previous legislation, including a deadline of April 1,
2007, for DHS to implement a long-range vessel tracking system,66 and a deadline of January 1,
2009, for issuing TWIC cards and for all ports to implement TWIC readers.67 In addition, the act
required by December 31, 2008, that all containers entering U.S. ports be subject to radiation
detection scanning.68
Title II of the SAFE Port Act focused on international supply chain security, defined by Section 2
of the act as the “end-to-end process for shipping goods to or from the United States beginning at
the point of origin (including manufacturer, supplier, or vendor) through a point of distribution to
the destination.” The Title includes five main provisions with respect to maritime cargo security,
which are summarized here and discussed in greater detail below:








Section 203 authorized cargo to be screened through CBP’s Automated Targeting
System (ATS; see “Automated Targeting System”) and further authorized DHS to
require advanced electronic cargo data (see “Advance Electronic Cargo
Information”) as needed to improve ATS targeting.69
Section 205 authorized the Container Security Initiative (CSI; see “Import
Security Scanning and Inspections”), designed “to identify and examine or search
maritime containers that pose a security risk before loading such containers in a
foreign port for shipment to the United States.” The section authorized DHS to
designate particular foreign seaports to participate in the CSI, and directed DHS
to establish criteria and procedures for nonintrusive inspection (NII) and for
nuclear and radiological detection systems at CSI ports.70
Sections 211-223 authorized the Customs-Trade Partnership Against Terrorism
(C-TPAT; see “Trusted Trader Programs”) and set forth C-TPAT program
parameters. C-TPAT is a voluntary program that allows certain trade-related
firms to be certified by CBP as having secured the integrity of their supply
chains. The law established three tiers of C-TPAT membership, and described
potential membership benefits associated with each.71
Section 231 directed DHS to establish pilot programs in three foreign seaports to

inspection.72 The program is known as the Secure Freight Initiative (SFI; see
“Import Security Scanning and Inspections”).
Section 232 required that 100% of cargo containers originating outside the
United States and imported into the United States be screened by DHS to identify
high-risk containers. As enacted, the section required DHS to ensure that
containers identified as high risk during the screening process also be scanned
through NII and radiation detection equipment before they arrive in the United
States (see “100% Scanning Requirement”).73

Implementing Recommendations of the 9/11 Commission Act of 2007
(P.L. 110-53)
The 9/11 Act of 2007 included two provisions with respect to the import process. Section 1602 of
the 9/11 Act required, by August 3, 2010, that 100% of air cargo bound for the United States or
traveling within the United States be subject to scanning or inspection commensurate with
standards established for passenger checked baggage.74
Section 1701 of the 9/11 Act amended the SAFE Port Act to require by July 1, 2012, that 100% of
maritime containers imported to the United States—that is, whether or not they are identified as
high-risk during the ATS screening process—be scanned by NII and radiation detection
equipment before being loaded onto a vessel in a foreign port. The act authorized the secretary of
DHS to extend the deadline by two years, and in additional two-year increments, by certifying
that scanning systems are not available, are insufficiently accurate, cannot be installed, cannot be
integrated with existing systems, will significantly impact trade and the flow of cargo, and/or do
not provide adequate notification of questionable or high-risk cargo (see “100% Scanning
Requirement”).75

The Import Process
Under the Homeland Security Act of 2002 (P.L. 107-296) as amended in 2003, CBP is the lead
agency charged with enforcing the trade laws under the Mod Act and the security measures under
the MTSA, the SAFE Port Act, and the other post-9/11 laws. CBP’s trade strategy emphasizes
risk management, which means that CBP collects advance information about shippers, importers,
and cargo to evaluate cargo for potential import security and trade enforcement risks, and focuses
enforcement efforts primarily on cargo and shippers identified as relatively high risk.76
Conversely, those deemed lower-risk imports (including, e.g., shipments of “trusted traders”) are
less likely to be targeted for CBP enforcement and may be eligible for expedited processing—
thus advancing CBP’s trade facilitation goal and freeing up resources for targeting higher-risk
imports.

U.S. Customs and Border Protection: Trade Facilitation, Enforcement, and Security

Import Security and Trade Enforcement Terminology and Procedures
As discussed throughout this report, cargo being imported to the United States may be subject to multiple and varied
types of import security and trade enforcement reviews, including the following:


Screening: A risk assessment based on an analysis of data elements (e.g., cargo manifest, country of origin,
shipper and consignee information) provided by an importer or carrier.



Scanning: An analysis of container contents based on non-intrusive inspection (NII) technologies, including
x-ray and gamma ray imaging systems and other technologies. NII scanning produces a high-resolution image of
container contents that is reviewed by law enforcement officers to detect hidden cargo and other anomalies that
suggest container contents do not match reported manifest data. If an officer detects an abnormality, containers
may be “cracked open” for a physical examination. Scanning may also refer to radiation detection.



Radiation detection: An analysis of container contents based on radiation portal monitors, handheld radiation
detection monitors, and/or other radiation detection technology to detect nuclear material that may be part of a
nuclear weapon or dirty bomb.



Examination: A physical examination of container contents (requires that the container be opened and, in
some cases, unpacked).



Primary inspection: A review of entry documents to determine whether cargo may be admissible to the
United States.



Secondary inspection: A review of container contents to confirm that cargo is admissible to the United
States. Secondary inspections may include NII scanning and/or a physical examination of container contents.



Liquidation: The final assessment of import-related taxes and fees; typically occurs a year or more after cargo
enters the United States.
Source: CRS analysis of the SAFE Port Act of 2006 (P.L. 109-347) and CBP briefing materials.

CBP’s trade strategy also emphasizes layered enforcement, meaning that risk assessment and riskbased enforcement happen at a number of different points in the import process, beginning well
before cargo arrives at a U.S. port of entry, and continuing long after cargo has been formally
admitted to the United States. CBP attempts to target high-risk flows as early as possible in the
import process, but its ability to conduct enforcement activities at different stages of the import
process is designed to create multiple opportunities to interdict illegal imports.
The import process includes three main stages, as illustrated in Figure 1. First, prior to entry at a
U.S. POE, importers and carriers file paperwork and provide advance electronic cargo
information, and all imports are subject to risk-based screening. Based on the results of this
screening, certain goods are subject to import security scanning and inspection in foreign ports
and/or upon arrival at a U.S. port. Second, importers file “entry documents” when cargo reaches a
U.S. port, and cargo may be subject to additional scanning and inspection for import security and
trade enforcement purposes. Admissible cargo is released from the port, and importers file an
additional set of “entry summary” documents, which CBP uses to calculate customs duties and to
make an initial assessment of taxes, fees, and duties owed. Third, following cargo entry, importers
may challenge the assessment for up to a year, or longer under certain circumstances, until the
final assessment of taxes and fees, a process known as liquidation. Trade enforcement activities
may continue through audits and other post-entry investigations.

Notes: Import security includes screening, scanning, and inspections to detect chemical, biological, radiological,
and nuclear (CBRN) weapons, illegal drugs, and other contraband; trade enforcement includes screening,
scanning, and inspections to detect trademark and copyright violations, unsafe products, and illegal agricultural
products, and to ensure proper collection of tariffs, fees, and anti-dumping and countervailing duties (AD/CVD).

Pre-Entry: Advanced Cargo Screening, Scanning, and Inspections
The import process begins well before cargo arrives at a U.S. port of entry (POE). During the preentry stage of the process, importers of record submit electronic cargo manifests and other
shipment data to CBP. This information may be submitted through CBP’s Automated Customs
System (ACE) or its Automated Customs Environment (ACE; see “Text Box: CBP’s Data
Management Systems,” below). CBP uses these advanced filing data to pre-clear cargo for
admission, facilitate inflows, and target certain cargo for import security and trade enforcement.
Cargo may be subject to import security scanning and inspections in foreign ports prior to being
loaded on U.S.-bound ships and/or upon arrival at a U.S. port of entry (POE).

U.S. Customs and Border Protection: Trade Facilitation, Enforcement, and Security

CBP’s Data Management Systems
Each stage of the import process involves an ongoing exchange of information between CBP and importers. CBP
manages two systems for tracking this information and for managing the collection of import duties and other traderelated fees: the Automated Commercial System (ACS) and the Automated Commercial Environment
(ACE). Both of these systems serve as data management systems for CBP and as contact points for trade partners to
submit electronic data to CBP, to receive information about the status of their shipments, and to make payments and
manage customs accounts.
The ACS began operating in 1984 and relies on mainframe computer hardware and software that are considered at
least a generation out of date, factors which reportedly limit ACS functionality and reliability. The U.S. Customs
Service created ACE in 2001 to begin replacing ACS, a transition known as “customs modernization.” The challenge
in the customs modernization process is to create a new data management system that meets all of CBP’s trade
enforcement and import security needs, while supporting a streamlined import process for legitimate importers, and
to test and implement the new system without disrupting trade flows during the transition period.
To this end, CBP has initiated ACE as a series of modules that encompass discrete phases of the import process. In
general, as new ACE modules are introduced, importers initially are permitted to use either ACS or ACE for the
affected task; and once the new ACE component has been tested and proven effective, importers are required to use
the ACE components as certain ACS functions are disabled. CBP’s eventual goal is to eliminate the ACS, and for ACE
to provide a single point-of-access and data management system covering the entire trade process for all U.S.
importers.
According to CBP’s office of legislative affairs, trade users may use their ACE accounts to pay duties and fees and to
generate 125 downloadable and customized reports. As of March 2012, electronic manifest data for truck, rail, and
ocean shipments may be filed through ACE at all U.S. POEs. Air and multi-modal integration is anticipated, but not yet
planned. On September 29, 2012, ACE became the only CBP-approved Electronic Data Interchange (EDI) for
submitting rail and sea manifests.
On October 18, 2014, CBP added a new ACE Automated Brokers Interface (ABI) query capability to request entry
record status, cargo and manifest information on file with ACE. On January 3, 2015, a series of new ACE capabilities
were launched including the transmission of antidumping and countervailing duty entries; electronic bond processing
for both Single Transaction Bonds and Continuous Bonds; and the deployment of an import air manifest. CBP plans
on completing trade processing capabilities in ACE and decommissioning similar capabilities in its other system by the
end of 2016.
CBP is working to transition cargo processing to the ACE, which is being developed as the primary system CBP and
all federal partner government agencies (PGAs) will use as a “single window” to track, control, and process all
imported and exported goods. To that end, CBP has announced three key dates. On May 1, 2015, CBP will require
mandatory use of ACE for all electronic manifest filing. On November 1, 2015, use of ACE will be mandatory for all
electronic cargo release and related entry summary filing. On October 1, 2016, all remaining electronic portions of
the CBP cargo process will be required to be completed through ACE.

Deployment D–January 2015 Release Capabilities for the Trade Community”.

Trusted Trader Programs
One of CBP’s primary tools for risk management is the use of trusted trader programs, including
the Customs-Trade Partnership Against Terrorism (C-TPAT), which was established in November
2001, after the 9/11 attacks, and subsequently authorized as part of the SAFE Port Act of 2006
(see “Security and Accountability For Every (SAFE) Port Act of 2006 (P.L. 109-347)”). Trusted
trader programs are voluntary public-private partnership programs that permit certain importrelated businesses to register with CBP, follow instructions prescribed by the agency to secure
their supply chains, and thereby become recognized as low-risk actors and become eligible for
expedited processing and other benefits. These programs are described in greater detail in the text
box below.

Congressional Research Service

18

U.S. Customs and Border Protection: Trade Facilitation, Enforcement, and Security

CBP Trusted Trader Programs
Customs-Trade Partnership Against Terrorism (C-TPAT)

C-TPAT is open to U.S. importers, customs brokers, and port and terminal operators; Mexican and Canadian
manufacturers and certain other foreign manufacturers; rail, sea, air, and truck carriers; and U.S. consolidators
and certain other logistics providers.

Businesses may apply to join C-TPAT by filling out an on-line application and submitting a supply chain security
profile that meets or exceeds minimum standards established by CBP. The security profile includes a narrative
description of measures in place to ensure the security of cargo at all stages of the company’s supply chain,
including procurement, production, packing, storage, loading, and transportation of goods for import. CBP
reviews profiles within 90 days and reviews company compliance histories. Upon a favorable review, the
company is certified as a Tier I C-TPAT partner.

Within one year of a C-TPAT partner being certified, CBP conducts a physical examination of the company’s
supply chain to validate that the security measures described in the profile are in place. Companies that meet
minimum security criteria are validated as Tier II C-TPAT partners, and companies that show a sustained
commitment beyond minimal security expectations are validated as Tier III partners.

Membership in C-TPAT reduces an importer’s ATS risk score, with greater reductions for Tier II and Tier III
members. C-TPAT members are less likely than non-members to be selected for security or trade related
scanning.

Certified C-TPAT members are also eligible for expedited processing at POEs and for expedited treatment when
containers are selected for scanning or inspection. C-TPAT permits stratified exams, so that if an entry with
multiple line items is selected for secondary inspection, only the selected container(s) are detained for
inspection, minimizing importers’ storage costs. (For non-C-TPAT members, multiple containers may be delayed
when a single container must be examined.) CBP’s business-resumption plans also call for C-TPAT members to
have front-of-the-line privileges in the event of a future port closure.

As of September 30, 2013, over 10,662 trade partners were certified as C-TPAT members and 2,235 companies
were validated or re-validated in FY2013, according to CBP.
Free and Secure Trade System (FAST)

FAST is open to commercial truck drivers who have completed background checks and fulfill eligibility
requirements and whose imports have supply chains that are fully C-TPAT certified.

FAST members are eligible to use dedicated FAST lanes at certain land POEs. FAST lanes generally have shorter
wait times and faster processing.

More than 78,000 commercial drivers are enrolled in the FAST program, and 17 ports at the northern and
southern borders have FAST lanes.
Importer Self-Assessment Program (ISA)

The ISA is open to C-TPAT members who are residents of the United States, have a two-year import history,
and are known importers that have businesses physically established, located, and managed within the United
States.

Importers must demonstrate a willingness to maintain an ongoing, mutually beneficial trade relationship with
CBP, the ability to manage and monitor their ongoing compliance with trade laws through self-assessment, and
the willingness to demonstrate an ongoing compliance through internal controls and annual risk assessments.

Accepted ISA importers are assigned a National Account Manager who serves as a liaison between CBP and the
importer, and identifies and resolves issues through consultation.

ISA members receive guidance from CBP upon request and are exempted from the comprehensive audit pool
known as Focused Assessment Audit (single issue audits may be conducted to address specific concerns).

As of November 17, 2014, CBP reports that 308 companies participate in the Importer Self-Assessment
Program, accounting for 23% of U.S. imports by value.
Mutual Recognition Arrangements

As of June 27, 2014, CBP has established mutual recognition arrangements with Canada, the European Union,
Israel, Japan, Jordan, Mexico, New Zealand, South Korea, and Taiwan.77 These arrangements allow C-TPAT
members and trusted traders to receive similar benefits in partner countries as those in the United States.

Advance Electronic Cargo Information
Under the Trade Act of 2002, as amended, importers and carriers seeking to import goods to the
United States must provide DHS with electronic manifest and other data prior to arrival in U.S.
ports. Carriers are required to provide names and addresses of shippers and consignees, detailed
descriptions of the goods being imported, information about the carrier, and information about the
day, time, and port of arrival. Specific filing requirements differ by mode of entry (truck, rail,
maritime, or air) and in some cases by country of origin (see text box below).
Deadlines for Submission of Electronic
Manifests and Other Shipping Data
Air Cargo (North America, Caribbean, Central America, and South America north of equator): Prior to aircraft
departure bound for the United States (wheels up)
Air Cargo (Other countries of origin): 4 hours prior to arrival
Rail Cargo: 2 hours prior to arrival
Truck Cargo: 1 hour prior to arrival, or 30 minutes prior to arrival for C-TPAT members
Maritime Cargo: Importer data due 24 hours before cargo is loaded on vessel bound for the United States; carrier
data due 24 hours prior to loading in a foreign port for containerized and break-bulk cargo or 24 hours prior to
arrival at the first U.S. port for bulk cargo, with updates as they occur.
Source: 19 C.F.R. §§4, 122-123.

Maritime Cargo: 10 + 2 Importer Security Filing
Maritime cargo is subject to additional reporting requirements under Section 203 of the SAFE
Ports Act and an interim final rule published by CBP on November 25, 2008.78 Under the rule,
maritime vessels must submit Importer Security Filings (ISF) and Additional Carrier
Requirements known collectively as “10 + 2” filings—so-called because they include 10 data
elements to be submitted by importers of record, plus 2 data elements to be submitted by carriers.
The 1079 data elements supplied by importers are
1. importer of record number;
2. consignee number;
3. seller name and address;
4. buyer name and address;
5. ship-to party name and address;
6. manufacturer (supplier) name and address;
7. country of origin;
8. Harmonized Tariff Schedule (HTS) 6-digit classification;
9. container stuffing location; and
10. consolidator (stuffer) name and address.
The two data elements provided by carriers are
78

P.L. 109-347 §203; 19 C.F.R. §§4.7–4.7d; also see 73 Federal Register 71730.
Ten data elements are required for all maritime cargo destined for U.S. entry. If cargo is transiting through the United
States, only five elements are required: booking party name/address; ship to party; harmonized tariff schedule (HTS)
classification; foreign port of unlading; and place of delivery.

1. the vessel stow plan; and
2. daily messages with information about any changes in container status.80
The first 8 importer data elements must be provided 24 hours prior to lading of the goods on a
vessel. Information on the stuffing location and the consolidator must be filed as soon as possible,
but no later than 24 hours before arrival in the United States. Regarding the carrier data, the
vessel stow plan must be provided no later than 48 hours after departure, and container status
messages must begin within 24 hours of creation or receipt of the container.

Automated Targeting System
Electronic manifests and other advanced data elements (including the 10+2 data elements
mentioned above) are forwarded to CBP’s Automated Targeting System (ATS). CBP officers
screen imports by comparing cargo and conveyance information against intelligence from CBP’s
National Targeting Center (NTC) and other intelligence and law enforcement databases. The ATS
assigns every incoming container a risk-based score related to weapons of mass destruction,
narcotics, and other contraband, as well as for the potential for commercial fraud, and other
customs violations.81 The rule-sets for assigning risk scores are designed to identify suspicious
activity or behavior and are updated on an ongoing basis in response to changes in intelligence
and previous enforcement records.

Import Security Scanning and Inspections Abroad
The SAFE Port Act of 2006 authorizes a pair of programs to conduct radiation detection and NII
scanning in foreign ports: the Secure Freight Initiative and the Container Security Initiative.

Secure Freight Initiative (SFI)
The Secure Freight Initiative (SFI) is a pilot program to test CBP’s ability, working with
international partners, to conduct radiation detection and NII scanning of 100% of cargo
containers being loaded on U.S.-bound ships in certain ports. The SFI employs an integrated
scanning system consisting of radiation portal monitors (provided by the Department of Energy)
and NII imaging systems (provided by CBP) in a single location. CBP officers review the
scanning data to determine which containers should be subject to secondary inspections.
Secondary inspections, when called for, are conducted by host-state law enforcement agencies.
In 2007, Section 1701 of the Implementing Recommendations of the 9/11 Commission Act of
2007 (9/11 Act; P.L. 110-53) amended the SAFE Port Act to require that by July 1, 2012, 100% of
maritime containers imported to the United States—that is, from all ports, whether or not they are
identified as high-risk—be scanned by NII and radiation detection equipment before being loaded
onto a U.S.-bound vessel in a foreign port. Pursuant to law, the program began operation operated
in three foreign ports in 2007: Port Qasim in Pakistan, Puerto Cortes in Honduras, and
Southampton in the United Kingdom. The pilot was also subsequently implemented on a limited

The ATS includes modules for inbound cargo and conveyances; outbound cargo and conveyances; air, ship, and rail
passengers; private vehicle land passengers; international cargo outside the United States; and a trend analytic module.
Only the inbound cargo and conveyance module is discussed in this report, though some features of the ATS are
common to more than one module.

basis in the larger ports of Port Salalah in Oman, Port Busan in South Korea, and Singapore.
Following DHS’s evaluation of the program, however, the program was scaled back and currently
operates only in Port Qasim.82
On May 2, 2012, however, then-DHS Secretary Janet Napolitano notified Members of Congress
that she would exercise her authority under the 9/11 Act to extend the deadline for 100%
scanning.83 In May 2014, DHS Secretary Jeh Johnson extended the deadline for an additional two
years.84 In the May 2014 letter, Secretary Johnson added that “DHS’s ability to fully comply with
this unfunded mandate of 100 percent scanning, even in [the] long term, is highly improbable,
hugely expensive, and in our judgment, not the best use of taxpayer resources to meet this
country’s port security and homeland security needs.”85 The Secretary also stated that he had
instructed CBP to fulfill the underlying objective of 100% scanning by, among other things,
making refinements to its layered-security/risk-management strategy86

Container Security Initiative (CSI)
The Container Security Initiative (CSI) is a partnership program among CBP, Immigration and
Customs Enforcement, and law enforcement agencies in CSI countries. Under the program, CBP
officers and other federal agents at the National Targeting Center–Cargo (NTC-C) in Herndon,
VA, review advanced sea cargo data and identify high-risk containers. High-risk containers are
targeted for radiation detection and NII scanning within CSI ports. Host state law enforcement
agents typically conduct physical scans in the foreign ports, and CBP personnel located in the
port or in the United States evaluate the scan results. When an abnormality is detected, host state
law enforcement agents conduct a physical inspection before the container is loaded on a U.S.bound ship. CBP officers and ICE agents participate in such inspections either remotely or as
partners within foreign ports.
According to CBP, the CSI is operational in 58 foreign seaports in 30 countries; approximately
80% of all U.S. incoming maritime containerized cargo originates in or transits through a CSI
port.87 About 1% of all cargo passing through CSI ports bound for the United States is scanned
using radiation detection technology and NII scanning prior to being shipped to the United States

cannot be installed, cannot be integrated with existing systems, will significantly impact trade and the flow of cargo,
and/or do not provide adequate notification of questionable or high-risk cargo. In her notification to Congress,
Secretary Napolitano certified that the use of systems to scan containers would have a significant and negative impact
on trade capacity and cargo flows, and that systems to scan containers cannot be purchased, deployed, or operated at
overseas ports due to limited physical infrastructure.

(also see “100% Scanning Requirement”).88 CBP reported that in FY2013, CBP officers reviewed
11,228,203 bills of lading and conducted 103,999 examinations of high-risk cargo in cooperation
with host country counterparts.89

Import Processing At Ports of Entry
Imported goods are not legally entered until after the shipment has arrived within the port of
entry, entry of the merchandise has been authorized by CBP, and all estimated duties have been
paid.90 The importer of record (i.e., the owner, purchaser, or a licensed customs broker) has the
option to enter the goods for consumption, enter them into a bonded warehouse at the port of
entry, or to transport the cargo in-bond to another port of entry for processing.
If goods are being entered for consumption (e.g., going directly into U.S. commerce) importers
are typically required to file entry documents within 15 calendar days of a shipment arriving at a
U.S. port of entry. These documents may include an entry manifest or other form of merchandise
release, evidence of the right to make entry, commercial invoices, packing lists, and other
documents necessary to determine admissibility. Since most cargo is released electronically,
however, packing lists and invoices are rarely requested.
Importers also must provide evidence that a bond has been posted with CBP to cover estimated
duties, taxes, and charges that may accrue. If the goods are to be released from CBP custody, an
entry summary must be filed and estimated duties deposited at the port within 10 days of the
entry of the merchandise.
Based on screening of the cargo and a review of the entry documents, CBP officers at the port
make a preliminary determination about cargo admissibility and either release or challenge the
shipment. For cargo that is challenged, importers may be required to provide additional
documents or take other steps to prove admissibility.

Import Security and Trade Enforcement at U.S. Ports
Radiation Scanning
The SAFE Port Act91 requires that 100% of cargo containers passing through U.S. POEs be
scanned for radioactive material prior to being released from the port. Containers typically pass
through drive-through portals at about five miles per hour, and radiation detection requires a few
seconds per container, apart from congestion.92 Portals are often placed at natural choke-points,
including near port exits or entrances to facilitate 100% radiation scanning. A radiation alarm may
be triggered by naturally occurring radiation found in granite and other stone or by radioactive
medical or scientific materials. When radiation is detected, further tests are conducted, including
more sophisticated scanning or physical inspection, to match the radioactive profile detected
against known radioactive materials in the shipment, or to identify and remove illegal radioactive
material.

U.S. Customs and Border Protection: Trade Facilitation, Enforcement, and Security

As of August 2012, CBP reported that 100% of containerized cargo entering through Northern
and Southwest border land ports and 99.8% of containerized sea cargo is scanned through
radiation portal monitors (RPMs).93 According to a 2012 GAO report, however, radiation
scanning of international rail cargo mainly is conducted with less powerful portable, hand-held
scanners; and scanning may only be triggered when NII scanning indicates a cause for alarm.94
Another GAO report found that CBP’s radiation portal monitors may not detect certain nuclear
materials when they are lightly shielded, and that such shielding may not be detected in the
absence of NII scanning.95 GAO also has identified problems with the acquisition of RPMs by
CBP and by DHS’s Domestic Nuclear Detection Office.96

Non-Intrusive Inspection (NII) and Secondary Inspections in U.S. Ports
Within each port, officers in CBP’s Advanced Targeting Unit use the ATS to select containers at a
high risk for weapons of mass destruction, drugs, or other contraband for NII scanning.
Containers with risk scores above a certain threshold are automatically selected for such scans,
and officers also may select additional containers for NII scanning and/or physical inspection.
Table 1 lists the number of rail, truck, and maritime cargo containers inspected by CBP between
FY2005 and FY2013 (i.e., the total number processed for entry), and the number subject to
secondary inspection, including NII scanning, physical inspection, or both.

Notes: Data include inspections of empty and full containers. Secondary inspection includes non-intrusive
imaging (NII) scanning and/or opening a cargo container for physical inspection.

As Table 1 indicates, the majority of cargo containers between FY2005 and FY2013 entered by
ship (about 101 million out of 220 million containers, or 46%) or by truck (about 95 million, or
44%), with the remainder entering by rail (about 24 million, or 11%). Secondary inspection rates
vary greatly by mode of entry, with 91% of all rail containers being scanned or inspected, versus
28% of truck-mounted containers, and 5% of maritime containers. Overall, about 25% of all
incoming containers (6.1 million out of 24.3 million) were subject to secondary inspection in
FY2011.
The different NII scanning percentages may reflect differences in port infrastructure and the
shipping process, among other factors. While land ports are naturally structured as choke points
with a relatively limited number of trucking or rail lanes, sea ports are larger facilities, and
containers from any given ship may flow in multiple directions before being placed on another
ship, rail, or truck conveyance. Truck and rail cargo also may be more regular than maritime
cargo (i.e., one type of good per container), whereas maritime containers may be more likely to
include multiple shipments bundled into a single container, making NII scanning more time
consuming. The flow of maritime shipping is also less regular than land-based modes. Whereas
truck and rail traffic arrives in a relatively steady stream at ports of entry, maritime cargo arrives
in surges, with each incoming ship containing hundreds or thousands of containers that must
quickly be processed.
Some Members have expressed frustration that most cargo is not scanned before entering the
United States, including the great majority of maritime cargo. However, while NII scans take less
than one minute per container overall, evaluating NII images and comparing them to declared
cargo manifests is a labor-intensive process that may involve multiple officers and may require up
to several minutes per container, depending on the complexity of the cargo. Thus, substantially
increasing the proportion of cargo scanned likely would be resource-intensive, and could slow the
flow of goods in and out of the United States. Moreover, CBP estimates that the overwhelming
majority of cargo entries are lawful,97 so that increased scanning may be of limited practical
benefit (also see “100% Scanning Requirement”).

Trade Enforcement Inspections
CBP trade specialists at POEs also target certain containers for trade enforcement inspections
based on ATS risk scores along with other intelligence and local enforcement considerations.
97

CBP projected the trade compliance rate (measured against transactional discrepancies) to be 98.9% in FY2012, and
the compliance rate averaged 98.0% for FY2006-FY2012; see CBP, Import Trade Trends: FY2011 Year End Report,
Washington, DC 2012, p. 17. Similarly, CBP’s audit of travelers at ports of entry found that about 99% of travelers at
air and land ports in FY2006 were in compliance with all relevant rules, laws, and regulations; see GAO, Border
security: Despite Progress, Weaknesses in Traveler Inspections Exist at Our Nation’s Ports of Entry, GAO-08-219,
November 2007, p. 47. And in FY2007-FY2010, CBP’s Office of Field Operations made a total of 168,504 drug
seizures at ports of entry—a figure which amounts to less than 0.2% of all cargo entries, and less than 0.01% of all
cargo and travelers entering through POEs; see DHS Office of Inspector General, CBP’s Efficacy of Controls Over
Drugs Seizures, OIG-11-57, March 2011, p. 3.

U.S. Customs and Border Protection: Trade Facilitation, Enforcement, and Security

Goods may be selected for trade enforcement examinations related to concerns about product
safety, intellectual property violations (copyright or trademark infringement), counterfeit goods,
labeling violations, or anti-dumping and countervailing duty (AD/CVD) circumvention, among
other considerations. Trade enforcement inspections ensure that goods are correctly classified and
accurately weighed for duty assessment, and administrative corrections are made as necessary.
Trade specialists also look for evidence of trade-related fraud (e.g., false rules of origin labeling
or valuation of merchandise), which may trigger an investigation by CBP trade specialists, ICE
investigators, or other federal agents.
CBP’s trade enforcement efforts are focused on five priority trade issues (PTIs), or “high risk
areas that can cause significant revenue loss, hurt the U.S. economy, or threaten the health and
safety of the American people.”98 The five issues are antidumping and countervailing duties;
import safety; intellectual property rights; textiles and apparel; and trade agreements.99 According
to CBP, these PTIs serve as the core of CBP’s trade enforcement strategy, and CBP focuses
considerable resources and personnel on them. CBP’s Performance and Accountability Report,
Fiscal Year 2013 reported gains in identifying “threats, challenges, and vulnerabilities in each
step” of the duty collection process, and in targeting textile and apparel manufacturers overseas
whose trade preference claims could not be substantiated.
Trade enforcement examinations can be a time-consuming procedure, especially in the case of
containers with diverse contents, because CBP officers must physically unpack the container and
examine all of its contents or a sample of contents. In some cases, such as when containers
include certain food, plant, or animal products, CBP officers may be required to bring in
representatives from other federal agencies (e.g., the U.S. Department of Agriculture) to assist
with physical inspections, and to determine whether or not a good may be admitted or how it
should be classified. Any storage and transportation costs associated with trade enforcement
examinations are borne by the importer, and may also occur outside the port at a centralized
examination station. As noted, one benefit of C-TPAT membership is that large shipments subject
to secondary inspection may be eligible for stratified exams, minimizing storage costs in these
cases (see “Text Box: CBP Trusted Trader Programs”).
As Table 2 indicates, about 2% (3.2 million out of 140.5 million) of all cargo containers seeking
admission to the United States were physically examined at a POE in FY2005-FY2013; and
slightly less than half (1.5 million out of 3.2 million) of physical examinations were trade-related
(as opposed to security-related). These examinations resulted in a total of 157,905 trade-related
seizures during this period, meaning that seizures occurred in about 10% of examined containers.
Most seizures were related to intellectual property violations (122,355 cases; 77% of trade-related
seizures) and import safety violations (24,503 cases; 16% of trade-related seizures).

Notes: Total inspections include the total number of loaded truck, rail, and maritime cargo containers
inspected. Examinations include cases in which cargo containers were opened and their contents physically
inspected.

Cargo Release
Cargo that is found to be admissible and cleared through security and trade enforcement
inspections is formally released into U.S. commerce. In these cases, importers must file additional
entry summary documentation within 10 days to provide detailed information about the shipment
(including customs classification, weight, and duty rates) that CBP will use to determine that all
import requirements have been satisfied.100 Importers must pay storage and transportation costs
during the cargo release period, and must pay initial customs duties and fees assessed prior to
taking possession of imported goods.

Trade Facilitation
Several CBP programs are in place that are designed to facilitate lawful trade during and after the
entry process, including CBP “Simplified Entry” process, its Centers of Excellence and Expertise
(CEE), and the in-bond transportation system.

Automated Commercial Environment (ACE) Cargo Release
(formerly “Simplified Entry”)
In April 2011, CBP established a joint industry-CBP working group to establish a simplified entry
process intended to reduce the administrative burden for importers, while providing the necessary
documentation needed by CBP officials to do their jobs of identifying risks and collecting tariffs,
taxes, and fees. The “Simplified Entry” process proposed to reduce the number of duplicative
data elements required to obtain release of products for cargo. The process allows filers to submit
100

In certain cases, including certain produce and other merchandise from Mexico and Canada, shipments consigned to
the U.S. government, and articles for a trade fair, shipments may be delivered immediately to the consignee, rather than
being held between formal entry and delivery as in the standard procedure described above. In these cases, importers
file entry documents and entry summary documents and pay estimated duties at the same time within 10 working days
of the cargo’s release.

a streamlined data submission of 12 required and 3 optional data elements. These data may be
filed early in the import process to allow an expanded window of opportunity to identify potential
risks. Filers may also update entry information throughout the import process to provide CBP
more accurate data.101
In December 2011, CPB began a simplified entry pilot program for air cargo. CBP selected 9
customs brokers (out of 40 applicants) operating out of 3 POEs (Chicago, Atlanta, and the
Indianapolis Express Consignment Operation). In August 2012, CBP opened the program to all
self-filers who hold a Tier-2 or higher C-TPAT status, and all importers who use customs brokers
to file simplified entry information.102 As of September 2013, over 159,000 simplified entries had
been filed for more than 1,100 importers.103
In November 2013, CBP re-named the program the “ACE Cargo Release Test,” and dropped the
C-TPAT requirement to allow more importers to participate. Eligible applicants are now accepted
on a first-come, first-served basis, but if the volume of applicants exceeds CBP’s administrative
capabilities, CBP reserves the right to select individual participants to ensure a diverse pool.104 In
February 2014, the test was expanded to cargo entries by ocean and rail; and to limited truck
entries at 10 POEs on May 2014.105

Centers of Excellence and Expertise
To facilitate post-entry processing, CBP has launched several Centers of Excellence and Expertise
(CEEs or Centers) since October 2011 to serve as industry-specific single points of post-entry
processing for certain businesses enrolled in the C-TPAT and ISA trusted trader programs.106 The
Centers are designed as “one-stop-shops” to align customs practices with the demands of modern
business and to facilitate trade in the targeted industries. CBP-integrated staff in the Centers
process entry summaries, post-entry amendment and correction reviews, protests, and other
administrative work.107
The 10 CEEs operating as of November 2012 are as follows:

of two additional Centers: Automotive and Aerospace in Detroit, and Petroleum, Natural Gas, and Minerals in Houston.

The Centers were designed so that the industries would receive fewer cargo delays, reduce costs,
and enjoy greater predictability, while CBP would be able to shift its emphasis at the ports of
entry to address higher-risk shipments and focus on trade enforcement issues. On a similar track,
an Account Executive (AE) pilot was established to work with selected trusted partners in the
electronics industry. At the end of these pilots, the two concepts were combined. The Centers also
support improved information sharing between industry representatives and CBP staff to lead to
more focused trade enforcement efforts.109

In-bond Transportation
In-bond transportation facilitates the efficient flow of goods trade into the United States by
allowing imported merchandise to arrive at one U.S. POE and be transported by a bonded carrier
to another U.S. POE, where it officially enters into U.S. commerce (duties are paid upon entry), is
exported out of the United States (duty payment is not required), enters a bonded warehouse
(duties are paid upon release), or is brought into a free trade zone for further processing (duties
are paid on the finished product upon entry).110 According to CBP, the four field offices that
process the most in-bond shipments are Los Angeles, New York, Miami, and Seattle.
Many in the trade community value the flexibility provided by the in-bond system as a way to
avoid congestion and delays at U.S. seaports, but a 2007 GAO report raised concerns that CBP
collects little information on in-bond shipments, does not know exactly how often th
