On June 3, 2025, President Trump signed a proclamation doubling Section 232 tariffs on imported aluminum and steel from 25% to 50%, citing the need to strengthen national security and industrial capacity. The revised tariff applies to both base and derivative articles, taking effect from June 4. However, aluminum and steel imports from the UK will remain at the original 25% unless the UK fails to meet obligations under the May 8 U.S.-UK Economic Prosperity Deal. A new tariff hierarchy prioritizes Section 232 duties over IEEPA-related tariffs on Canada and Mexico, and reciprocal tariffs now apply to all derivative goods, even with non-metal components.
New Customs and Border Protection (CBP) guidance outlines duty calculations based on aluminum or steel content. If the metal originates from U.S. sources (aluminum smelted and cast, steel melted and poured), the new tariffs do not apply. Importers must carefully report values, often splitting entries when non-metal content is involved. Derivative articles from Russia still face a 200% tariff. Importers can’t claim duty drawbacks, but existing exclusions remain valid until their set limits are reached. Products in Foreign Trade Zones must enter under privileged status.
The revised “tariff stacking” approach from Executive Order 14289 will be enforced for goods entered on or after June 4. Though EO 14289 applies retroactively from March 4, the updated prioritization begins only in June. Importers can request refunds for overpaid duties on affected entries through corrections or protests if within legal deadlines.
