Scope of the Investigation

The product covered by this investigation is hexamine from Saudi Arabia. For a complete description of the scope of this investigation,

see

Appendix I.

Scope Comments

We received no comments from interested parties on the scope of the investigation as it appeared in the

Preliminary Determination.

Therefore, we made no changes to the scope of the investigation from that published in the

Preliminary Determination

for the final determination.

Verification

As provided in section 782(i)(1) of the Tariff Act of 1930, as amended (the Act), in May 2025, Commerce verified the sales and cost information submitted by Chemanol for use in the final determination. We used standard verification procedures, including an examination of relevant sales and accounting records, and original source documents provided by Chemanol.

Analysis of Comments Received

All issues raised in the case and rebuttal briefs submitted by interested parties in this investigation are addressed in the Issues and Decision Memorandum. A list of the issues addressed in the Issues and Decision Memorandum is attached to this notice as Appendix II.

Final Negative Determination of Critical Circumstances

On August 27, 2025, Bakelite LLC (the petitioner) alleged that critical circumstances exist with respect to imports of hexamine from Saudi Arabia.

6

We determine that critical circumstances do not exist for Methanol Chemicals Company (Chemanol), and all other companies not individually examined pursuant to section 735(a)(3) of the Act and 19 CFR 351.206. For a discussion of Commerce's critical circumstances analysis,

see

the Issues and Decision Memorandum.

See

Petitioner's Letter, “Critical Circumstances Allegation,” dated August 27, 2025 (Critical Circumstances Allegation).

Changes Since the Preliminary Determination

We made certain changes to the margin calculation for Chemanol, since the

Preliminary Determination

and Post-Preliminary Analysis.

7

For a discussion of these changes,

see

the Issues and Decision Memorandum.

See

Memorandum, “Analysis for the Final Determination for the Methanol Chemicals Company,” dated concurrently with this notice.

All-Others Rate

Section 735(c)(5)(A) of the Act provides that Commerce shall determine an estimated all-others rate for all exporters and producers not individually examined. This rate shall be an amount equal to the weighted average of the estimated weighted-average dumping margins established for exporters and producers individually investigated, excluding any zero and

de minimis

margins, and any margins determined entirely under section 776 of the Act.

In this investigation, Commerce calculated an individual estimated weighted-average dumping margin for Chemanol, the only individually examined exporter/producer in this investigation. Because the only individually calculated dumping margin is not zero,

de minimis,

or based entirely on facts otherwise available, the estimated weighted-average dumping margin calculated for Chemanol is the margin assigned to all other producers and exporters, pursuant to section 735(c)(5)(A) of the Act.

Final Determination

Commerce determines that the following estimated weighted-average dumping margins exist for the period, July 1, 2023, through June 30, 2024:

Disclosure

Commerce intends to disclose the calculations performed in connection with this final determination to interested parties within five days of any public announcement or, if there is no public announcement, within five days of the publication of the notice in the

Federal Register

, in accordance with 19 CFR 351.224(b).

Continuation of Suspension of Liquidation

In accordance with section 735(c)(1)(B) of the Act, Commerce will instruct U.S. Customs and Border Protection (CBP) to continue to suspend liquidation of all entries of hexamine, as described in Appendix I of this notice, which were entered, or withdrawn from warehouse, for consumption on or after May 6, 2025, the date of publication of the

Preliminary Determination

in the

Federal Register

. These suspension of liquidation instructions will remain in effect until further notice.

Pursuant to section 735(c)(1)(B)(ii) of the Act and 19 CFR 351.210(d), upon the publication of this notice, we will instruct CBP to require a cash deposit for estimated antidumping duties for such entries as follows: (1) the cash deposit rate for exporters listed in the table above is the company-specific estimated weighted-average dumping margins listed for the respondents in the table; (2) if the exporter is not listed in the table above, but the producer is, then the cash deposit rate is the company specific estimated weighted-average dumping margins listed for the producer of the subject merchandise in the table above; and (3) the cash deposit rate for all other producers and exporters is the all-others estimated weighted-average dumping margin listed in the table above. These suspension of liquidation instructions will remain in effect until further notice.

U.S. International Trade Commission (ITC) Notification

In accordance with section 735(d) of the Act, Commerce will notify the ITC of our final affirmative determination of sales at LTFV. Because the final determination in this proceeding is affirmative, in accordance with sections 735(b)(2) of the Act, the ITC will make its final determination as to whether the domestic industry in the United States is materially injured, or threatened with material injury, by reason of imports of hexamine from Saudi Arabia no later than 45 days after this final determination. If the ITC determines that such injury does not exist, this proceeding will be terminated, all cash deposits posted will be refunded, and suspension of liquidation will be lifted. If the ITC determines that such injury does exist, Commerce will issue an antidumping duty order directing CBP to assess, upon further instruction by Commerce, antidumping duties on all imports of the subject merchandise entered, or withdrawn from warehouse, for consumption on or after the effective date of the suspension of liquidation, as discussed in the “Continuation of Suspension of Liquidation” section above.

Administrative Protective Order (APO)

This notice serves as a final reminder to parties subject to an APO of their responsibility concerning the return or destruction of proprietary information disclosed under APO in accordance with 19 CFR 351.305(a)(3), which continues to govern business proprietary information in this segment of the proceeding. Timely written notification of the return or destruction of APO materials, or conversion to judicial protective order, is hereby requested. Failure to comply with the regulations and the terms of an APO is a violation subject to sanction.

Notification to Interested Parties
