Trump Restructures Section 232 Steel, Aluminum, and Copper Tariffs

Trump signed a proclamation under Section 232 restructuring tariffs on steel, aluminum, copper, and derivative products. Articles made almost entirely of those metals now face a flat 50% tariff on full customs value, up from a narrower base calculation. The new rates take effect at 12:01 a.m. ET on April 6, 2026, aligning with the one-year anniversary of 'Liberation Day' tariffs. Trading partners warned of retaliatory measures.
