in effect
Proclamation 11021, signed April 2, 2026, is a presidential order that modifies existing Section 232 national-security tariffs on imports of aluminum, steel, and copper. It adjusts how those tariffs are calculated, changes which products they cover, and sets new rates — all effective April 6, 2026.
Tariffs now apply to the full customs value of a covered product, not just to its metal content, regardless of how much metal is actually in the item. The standard rate rises to 50 percent for most aluminum and steel articles and certain derivatives; a separate 25 percent rate applies to a second list of copper articles and other derivatives. Products made entirely from U.S.-smelted or U.S.-cast metal pay a reduced 10 percent rate, and qualifying United Kingdom products pay 25 percent or 15 percent depending on which list they fall under. A transitional rate structure — capped at a combined total of 15 percent — applies to a third category of derivative products through December 31, 2027, after which that group moves to the standard 25 percent rate. Certain products are removed from tariff coverage entirely (Annex II), while the formal public petition process for adding new derivative products is replaced by a joint administrative decision by the Secretary of Commerce and the U.S. Trade Representative.
U.S. importers of aluminum, steel, and copper — and of finished goods that contain those metals — face higher duties on goods entering after April 6, 2026, because the tariff base now covers the whole product value rather than just the metal portion. Domestic manufacturers that use U.S.-sourced metal may qualify for the reduced 10 percent rate, giving them a cost advantage over foreign competitors. Foreign exporters, particularly those outside the United Kingdom and without a concluded reciprocal trade agreement with the United States, face the full 50 or 25 percent additional duty.
