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.

new ACE country-of-smelt/cast reporting fields for copper under Proclamation 11021; introduces no new duty rate or Chapter 99 measure.

CBP added new entry-reporting fields (country of smelt, country of cast) for certain copper classifications, effective July 30, 2026. This is a data-collection and filing requirement, not a rate change; the Section 232 copper duties themselves are unchanged.

Section 232 investigation of anthracite/metallurgical coal at the public-comment stage; no duty imposed.

The Commerce Department opened a Section 232 investigation into anthracite and metallurgical coal imports (HTS 2701.11 and 2701.12) and is taking public comment through July 21, 2026. No duty is imposed at this stage, so no rates change. We will update if it results in tariffs.
