On June 3, 2025, President Trump issued a proclamation adjusting the tariffs on imported aluminum and steel from 25% to 50%. The new, higher rate will take effect starting on June 4, 2025. An exception has been provided in regards to the imports from the United Kingdom (U.K.). Steel and aluminum imported from the U.K. will remain at 25% rate until July 9, 2025. After this date, the Commerce Secretary has the authority to modify the applicable duty rates for U.K. imports.

On June 3, 2025, Customs and Border Protection (CBP) provided entry guidance on Steel, Steel Derivatives, Aluminum and Aluminum Derivatives; addressing the increased tariff adjustments referenced in the Presidential Proclamation.
