Effective April 6, 2026, Section 232 tariffs on aluminum, steel, and copper now apply to the full customs value of imported products. The updated structure sets rates of 50% for metal articles, 25% for metal-heavy derivatives, and a transitional 15% through 2027 for industrial and electrical grid equipment. Products made entirely with US-origin metal qualify for 10%, while goods with 15% or less metal content are removed from scope. CBP guidance now available.
