Further Adjusting the Tariff Regimes for Imports of Aluminum, Steel, and Copper into the United States
Impact Score: 4
Timeline: Effective June 8, 2026, with further adjustments starting January 1, 2028
Summary: This proclamation revises tariffs on imported aluminum, steel, and copper products under section 232 of the Trade Expansion Act of 1962, imposing a 50% duty on pure metal products, 25% on derivatives, and a temporarily reduced 15% rate on selected machinery and equipment. It lowers the domestic content threshold from 95% to 85% to boost American sourcing and expands the categories subject to reduced tariffs. Implementation involves coordinated enforcement and ongoing review to address national security concerns.
Key Actions: Monitor tariff changes and impacts through Vanderbilt’s Office of Federal Relations and Procurement; evaluate research and sustainability initiatives in engineering and policy studies to leverage domestic sourcing; develop educational programs on trade impacts; and foster partnerships with local industry to adapt to and capitalize on tariff adjustments.
