Section 232 review ties Commerce national-security actions, steel and aluminum scope, derivative inclusions, and country exemptions to one importer review path.
This page is the public entry point. It explains the issue, links to the public tools that surface the primary records, and routes repeat work into review.
Use this when the first question is which Commerce action or proclamation changed the duty.
Use this when a product line must be matched against primary or derivative scope.
Use this when the duty depends on a country exemption, quota, or exclusion in force on the entry date.
Section 232 scope moves through proclamations and derivative inclusions, so a product that was outside the tariff one quarter can be inside it the next. Importers need to know when an action touches lines already under review.
Traverse keeps each Section 232 action tied to the affected HTS scope, country treatment, and primary record, so the duty question stays connected to the source instead of a headline.
Track Commerce determinations, Federal Register proclamations, steel and aluminum HTS scope, derivative product inclusions, country-specific exemptions or quotas, and effective dates that change the duty owed at entry.
The rate depends on whether the product, its HTS line, and its country of origin fall inside the current scope, whether a derivative inclusion or exclusion applies, and whether a quota or exemption is in force on the entry date.
Review it when the same steel or aluminum HTS line, derivative part, or country of origin keeps coming back, instead of re-checking scope and exemptions one entry at a time.
The International Trade Administration has published procedures allowing domestic automobile and medium- and heavy-duty vehicle engine manufacturers to claim import adjustment offsets on parts imports under Proclamations 10925 and 10984. Limited-production engine assembly operations are excluded from offset calculations.
The Federal Register published a document on July 23, 2026 announcing further strengthening of Section 232 actions adjusting aluminum imports into the United States. Details of specific measures, rates, or country exemptions are not yet available from the source payload.
President Trump issued a proclamation on July 20, 2026 further tightening Section 232 aluminum import measures originally established under Proclamation 9704 (March 8, 2018). The action expands or modifies existing tariff-based adjustments on aluminum imports to address national security concerns.
Keep Commerce actions, derivative inclusions, country exemptions, and HTS lines together. Review Section 232 scope.
