In effect
CBP guidance

National-security tariffs on steel, in place since 2018 and sharply expanded in 2025–26: the rate doubled to 50% in June 2025, country exemptions ended, the duty base now covers the full customs value of derivative articles, and hundreds of downstream products were added. Proclamation 11032 reset the base rate to 25% from June 8, 2026 through December 31, 2027, with a 15% combined floor for listed partners including the EU, UK, Japan and Korea and a 15% transitional rate for certain metal-intensive equipment. Unaffected by the Supreme Court's IEEPA ruling.

Current rate: 25% on steel articles and derivatives (reduced from 50% on June 8, 2026, through December 31, 2027); 15% combined floor for the EU, UK, Japan, Korea, Taiwan, Switzerland, Liechtenstein, Argentina, Ecuador, El Salvador and Guatemala; 10% for derivatives made entirely (at least 85% by weight) from U.S.-smelted steel; USMCA goods dutied on non-U.S. content with a 15% floor

National-security tariffs on aluminum, expanded in lockstep with steel: 50% from June 2025 for all origins, derivative coverage broadened repeatedly, duties assessed on full customs value since April 2026, and — since Proclamation 11032 — a 25% base rate from June 8, 2026 through December 31, 2027 with a 15% combined floor for listed partners and a 15% transitional rate for certain equipment. A July 2026 proclamation lets companies building U.S. primary-aluminum capacity import at half the rate. Unaffected by the Supreme Court's IEEPA ruling.
