In a Cargo Systems Messaging Service (CSMS) bulletin published on October 31, 2025, U.S. Customs and Border Protection (CBP) provided guidance on the implementation of the import adjustment offset for Section 232 duties on automobile parts.

To take advantage of this guidance, Importers of record must be granted a Department of Commerce (DOC) import adjustment offset. This offset can only be claimed up to amount granted by the DOC.

For automobile parts originating from the European Union (EU), Japan, or the United Kingdom can only have the portion of the duties under Section 232. This would allow duties between the Section 232 duty and the column one rate to be offset.

The importer must report the automobile parts offset license number in the Importer Additional Declaration Field. Importers may also submit post summary corrections based on this guidance to claim the import adjustment offset for any Section 232 automobile parts duties on previous entry summaries.

The import adjustment offset became functional in the Automated Commercial Environment (ACE) on November 3, 2025.
