Beginning on November 1, 2025, the US Government will implement a 25% tariff on heavy and medium-duty trucks. 

Specifically, these tariffs will be set at 25% for classes III through VIII trucks and their parts, with a 10% tariff on buses. 

A senior White House official commented on the new proclamation, stating that there will be United States-Mexico-Canada Agreement (USMCA) favorable treatment for eligible imports of affected trucks, meaning that non-US content will be subject to the 25% while the US content of the vehicle will not be. 

Buses, however, will not be subject to the same treatment, and the entirety of the vehicle will be subject to the 10% tariff. 

Individual truck and bus parts imported from Mexico or Canada will be allowed to enter duty-free as long as they qualify for USMCA. 

Similar to cars and trucks assembled in the US, companies that assemble trucks in the US can get an offset of 3.75% of the manufacturer’s suggested retail price of the finished vehicle, provided the tariffs that were paid on the parts add up to that amount or more. 

Other notes: 

• In general, this proclamation refers to commercial vehicles. Details surrounding any tariffs relevant to personal vehicles can be found on our tariff page. 
• These new tariffs will apply to used and remanufactured trucks and buses, but only if they were manufactured in the last 25 years. 
• Japanese or European truck parts or heavy-duty engine parts will be subject to a 15% all-inclusive rate as opposed to the 25%
• Steel or aluminum imported from Canada or Mexico that was smelted and cast or melted and poured in those countries and is now used by car and truck manufacturers can be subject to 25% tariffs as opposed to 50%, including heavy truck and bus manufacturing. 

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.
