Tariffs on Medium- and Heavy-Duty Trucks Take Effect November 1, 2025

What’s Changing

• 25% tariff on imported medium- and heavy-duty trucks (Class 3–8).
• 25% tariff on imported truck parts, including engines, transmissions, tires, and chassis.
• 10% tariff on imported buses, including school buses, transit buses, and motor coaches.
• For medium- and heavy-duty trucks that do not qualify for preferential tariff treatment under the United States-Mexico-Canada Agreement (USMCA), the tariff will apply to the full value of the vehicle. For medium- and heavy-duty trucks that qualify for preferential tariff treatment under the USMCA, the tariff will only apply to the value of the non-U.S. content in the vehicle.
• USMCA-compliant parts remain tariff-free until the Secretary of Commerce establishes a process for applying duties to non-U.S. content.
• Domestic medium- and heavy-duty truck production will be incentivized by offering an offset to a portion of tariffs for medium- and heavy-duty truck parts equal to 3.75% of the aggregate value of all trucks assembled in the United States from 2025 through 2030. This percentage reflects the duty that would be owed when a 25% tariff is applied to 15% of the value of a U.S.-assembled medium- and heavy-duty truck.
• Products subject to tariffs under this proclamation will not be subject to additional or existing sectoral tariffs on steel, aluminum, copper, automobiles and automobile parts, and lumber; they also will not be subject to reciprocal tariffs or the tariffs imposed on Canada, Mexico, Brazil, or India.
