Currently, the Postal Service only requires mailers to include accurate parcel dimensions in a manifest (Shipping Services File (SSF) or other approved electronic documentation) when the dimensions exceed 1 cubic foot or 22 inches in length. Failure to comply with this requirement, would subject the parcel to the Dimension Noncompliance Fee.
The Postal Service is proposing to expand the current standard in the Domestic Mail Manual by requiring mailers to always include accurate dimensions (length, width, and height) for parcels included in a manifest
onic documentation) when the dimensions exceed 1 cubic foot or 22 inches in length. Failure to comply with this requirement, would subject the parcel to the Dimension Noncompliance Fee.
The Postal Service is proposing to expand the current standard in the Domestic Mail Manual by requiring mailers to always include accurate dimensions (length, width, and height) for parcels included in a manifest. Dimensions would not be required for Flat Rate priced pieces or USPS Returns pieces. Failure to comply with the expanded requirement, would continue to subject the parcel to the Dimension Noncompliance Fee. This proposal would also continue to only apply to commercial Priority Mail Express, Priority Mail, USPS Ground Advantage, and Parcel Select, products.
The Postal Service is proposing to implement this change effective July 12, 2026,
Although exempt from the notice and comment requirements of the Administrative Procedure Act (5 U.S.C. 553(b), (c)) regarding proposed rulemaking by 39 U.S.C. 410(a), the Postal Service invites public comment on the proposed revisions to Mailing Standards of the United States Postal Service, Domestic Mail Manual (DMM), incorporated by reference in the Code of Federal Regulations.
