Adjusting Imports of Aluminum and Steel Into the United States

This proclamation increases the Section 232 tariffs on imports of steel articles, aluminum articles, and their derivatives from 25 percent to 50 percent ad valorem, effective 12:01 a.m. eastern daylight time on June 4, 2025, with the duties applying only to the steel or aluminum content of covered articles. Imports from the United Kingdom remain at 25 percent, and on or after July 9, 2025, the Secretary of Commerce may adjust UK rates or raise them to 50 percent if the United Kingdom has not complied with the U.S.-UK Economic Prosperity Deal. The proclamation amends EO 14289 (Addressing Certain Tariffs on Imported Articles), directs U.S. Customs and Border Protection to issue guidance on steel and aluminum content declaration requirements with penalties for underreporting, and provides that no drawback is available for the duties imposed.
