Overview
- The White House fact sheet says President Trump signed a Section 232 Proclamation on July 20 directing the Commerce Department to create an incentive program that links tariff relief to U.S. primary aluminum investment.
- Under the program the Secretary of Commerce will approve onshoring plans and allow approved companies to import an equivalent amount of primary aluminum at a reduced tariff equal to half the otherwise applicable Section 232 rate.
- Reporting supplements the proclamation with specifics that Commerce has not yet finalized, describing temporary reduced-duty windows through December 31, 2027, a reported 15% ad valorem tier for some products, a lowered U.S.-content threshold from 95% to 85%, expanded derivative-product coverage, and carve-outs for the EU, UK, Canada and Mexico.
- The Commerce Department will monitor approved projects, require audits and can rescind tariff benefits, including retroactively, if companies fail to meet construction or production commitments or if fraud is found.
- The move builds on prior 2018 Section 232 tariffs and a 2025 copper expansion; primary aluminum is needed for high-strength military and aerospace alloys and onshoring plans must include firm commitments to build, refurbish, or expand smelters with construction start dates set by the administration.
