Commerce opens process for reduced 25% Section 232 steel/aluminum rate for Canadian, Mexican producers

A Commerce (ITA) notice under Proclamation 10984 sets procedures for steel and aluminum producers with facilities in Canada or Mexico that supply U.S. automobile or medium- and heavy-duty vehicle makers to apply for a reduced Section 232 tariff of 25% (under Proclamations 9704 and 9705) by committing to new U.S. primary steel or primary aluminum capacity. The reduced rate applies only to USMCA-qualifying steel melted and poured, or aluminum smelted and cast, in Canada or Mexico, and only to quarterly quantities tied to the committed new capacity, through a single designated importer of record after Commerce approval and notice to CBP. New HTS headings 9903.82.18 (steel) and 9903.82.19 (aluminum) take effect for goods entered on or after April 23, 2026, the same date submissions open. If a company fails to substantially meet its milestones, Commerce may pause the reduction or have CBP liquidate or reliquidate prior entries at the full applicable tariff.
