New Section 232 tariff adjustments on steel, aluminum, and copper took effect June 8, 2026. These changes will remain in place through December 31, 2027.

The policy reduces tariff rates from 25% to 15% for specific imported goods. This relief applies to agricultural machinery, residential HVAC systems, and mobile industrial equipment like bulldozers and forklifts.

The proclamation adds a 25% levy to imported steel racks and aluminum lithographic plates.

The U.S.-sourced content requirement for foreign-made equipment decreased from 95% to 85%. Meeting this threshold allows importers to qualify for a preferential 10% tariff rate.

Farming and construction industries expect lower equipment costs from these adjustments. Domestic metal producers view the changes as a refinement of the broader tariff structure.
