Actions announced

The new proclamation introduces strategic adjustments to balance national security with the needs of domestic industries. The main actions are:

• Temporary tariff reduction to 15%: Eligibility for an Annex III tariff benefit is expanded to include agricultural machinery and certain residential HVAC (heating, ventilation and air conditioning) systems. These products were previously subject to higher rates and will now enjoy a reduced tariff of 15% through the end of 2027.
• Inclusion of new derivative products: To avoid duty avoidance, aluminum lithographic plates and steel racks are added to the list of taxable derivatives.
• Adjustment of the U.S. origin threshold: The weight threshold for a product to be considered “wholly” made of U.S.-origin metals is reduced from 95% to 85%. This measure seeks to encourage the use of U.S.-produced metals in downstream products.
• Regime for mobile industrial machinery: Temporary modifications are established for mobile industrial equipment (Construction and Grading Machinery, Material Handling Vehicles…) under Annex I-C, with a default tariff of 25%, but with lower rates for specific trading partners.

Impact on European products

Products originating in European Union member states receive preferential treatment under the Annex I-C regime (steel and aluminum derivatives for mobile industrial machinery).

• 15% minimum tariff: If the general tariff (rate for standard imports) of the product is less than 15%, an additional Section 232 tariff will be applied to bring the total amount to exactly 15% ad valorem.
• Additional duty exemption: If the general duty is already 15% or higher, the additional Section 232 duty will be zero percent.
