US President Donald Trump signed a proclamation establishing an application program under Commerce Secretary Howard Lutnick to halve the current 50% import levy on aluminum. To obtain these reduced rates, businesses must submit plans to build, expand, or renovate domestic aluminum manufacturing facilities and commit to starting construction by January 20, 2029.
Approvals will depend on commercial viability and expected output, granting companies a 50% tariff reduction on import volumes matching their projected production capacity.
The White House provided no implementation timeline or additional requirements. This policy expands upon an earlier Commerce Department initiative for Mexican and Canadian producers, which demanded United States-Mexico-Canada Agreement (USMCA) compliance and extensive supply chain record-keeping.
