New Section 232 Action: What the June 2026 Aluminum, Steel & Copper Proclamation Means for Your Imports
Topline summary: On June 1, 2026, President Trump amended the Section 232 tariff framework for aluminum, steel, and copper. Importers of agricultural, industrial, and mobile equipment may qualify for temporarily reduced rates of 10–15%, while certain furniture parts, lithographic plates, and steel racks are newly dutiable for the first time. With a December 31, 2027, sunset on all temporary reductions, importers should audit their HTS classifications now to avoid overpaying or underpaying.
On June 1, 2026, the President issued Proclamation 11032, “Further Adjusting the Tariff Regimes for Imports of Aluminum, Steel, and Copper Into the United States,” amending the April 2026 Section 232 framework (Proclamation 11021). U.S. Customs and Border Protection (CBP) followed on June 5 with implementation guidance in CSMS #68855869. The changes take effect for goods entered for consumption, or withdrawn from a warehouse for consumption, on or after 12:01 a.m. ET on June 8, 2026.
This is not a uniform tariff cut. The proclamation does two opposite things at once. It reduces Section 232 rates on a large block of machinery and equipment, while simultaneously adding new products to the duty regime for the first time. If you import equipment, the change may help you. If you import certain furniture parts, lithographic plates, or steel racks, you may have just become newly dutiable.
