Changelog

an ACE entry-summary validation and CATAIR error-code update for the Section 232 auto-parts import adjustment offset; no rate, no Chapter 99 heading, and the offset is granted per importer license rather than resolvable from HTS and origin.

On July 18, 2026 CBP deployed a new validation in the Automated Commercial Environment for the Section 232 import adjustment offset on automobile and medium and heavy-duty vehicle parts, and posted an updated CATAIR Error Dictionary (V51) with new error codes covering the auto-part credit.

This is an entry-filing control. It checks that an importer's Automobile License declaration carries a sufficient balance and that duty is not also claimed on the corresponding Chapter 99 line. The offset itself is allocated per importer license, not per HTS code and country of origin, so it changes no published duty rate and is not something a rate API can resolve. Rates returned for automobile and vehicle-part codes are unchanged.
