President Trump signed Proclamation 11032 on June 1, 2026 (effective June 8, 2026), making further adjustments to Section 232 tariff regimes for aluminum, steel, and copper. The proclamation expands temporary 15% reduced ad valorem rates to cover agricultural equipment and certain residential HVAC systems previously subject to the 25% derivative tariff, and creates a new Annex I-C establishing temporary S232 rates for mobile industrial equipment and machinery through December 31, 2027. It also designates aluminum lithographic plates and steel racks as new derivative products subject to S232 duties as an anti-circumvention measure. All temporary modifications revert to Proclamation 11021 rates after December 31, 2027.

Presidential Proclamation 11021 of 2 April 2026 (signed by President Trump, effective 6 April 2026 at 12:01 a.m. EDT, published 9 April 2026 at 91 FR 18201) consolidates and restructures the Section 232 tariff architecture for aluminum, steel, and copper. The proclamation modifies Proclamations 9704 (aluminum), 9705 (steel), and 10962 (copper) and applies tiered ad valorem duties to the full customs value of imported articles regardless of metal content: 50% on aluminum/steel articles and most copper articles; 25% on certain copper articles and on derivative articles substantially made of the three metals; 10% on derivative articles produced abroad using entirely US-smelted/cast metals; and 0% supplemental duty where existing tariffs already meet a 15% combined-rate floor. UK products receive preferential rates (25% on primary articles and 15% on certain derivatives) contingent on UK smelting/casting under the US–UK trade framework.

President Trump signed two Presidential Proclamations on 11 February 2025 reinstating a universal 25% ad-valorem tariff on all steel-mill products and raising the aluminum tariff from 10% to 25% on all imports into the United States, effective 12 March 2025. The proclamations revoked every bilateral exclusion and quota arrangement negotiated by the Biden administration with the EU, UK, Japan, Korea, Australia, and others under the 2021-2022 "alternative measures" frameworks, returning all trading partners to the baseline Section 232 rate without product-level or country-level carve-outs.

On 9 December 2021, the U.S. Department of Commerce / BIS issued an interim final rule (86 FR 70003) removing 31 General Approved Exclusions (GAEs) from the Section 232 tariff exclusions framework — 27 for steel and 4 for aluminum. The removals followed Commerce's review of public comments on the 14 December 2020 interim final rule that first established the GAE pathway and additional analysis of exclusion-request submissions; Commerce concluded these 31 GAEs no longer met the criteria for blanket exclusion. Effective 27 December 2021, importers of the affected HTS-coded products must either file individual exclusion requests or pay the Section 232 duties of 25% (steel) and 10% (aluminum).
