The White House will impose new import taxes on trucks and buses starting Nov. 1, calling it a move to strengthen U.S. manufacturing. The plan includes options for automakers to reduce costs if their vehicles or parts are made partly in North America.
Tariffs to Reshape Truck and Bus Import Economics
The Trump administration will impose a 25% tariff on imported medium- and heavy-duty trucks and a 10% levy on buses starting Nov. 1, following a Section 232 national security probe concluded by the White House. The order, signed Friday, covers Class 3 through Class 8 vehicles, ranging from school and transit buses to large pickup, cargo, and dump trucks, and extends to critical components such as engines, chassis, and transmissions.
The executive order underscores the government’s view that foreign-built trucks and buses play a critical role in national logistics capacity. “These vehicles are essential for the continuity of American critical infrastructure and economic stability,” the order states, citing their role in moving over 70% of the nation’s freight, including food, fuel, and medical supplies.
However, the administration has sought to temper the potential impact through offset provisions. Importers that meet U.S.-Mexico-Canada Agreement (USMCA) origin rules may have the 25% tariff applied only to non-U.S. content. In addition, companies assembling heavy-duty trucks domestically can recover 3.75% of tariff costs annually for five years, beginning with the duty’s enforcement.
Commerce Department to Oversee Offset and Steel Adjustments
The Commerce Department will manage implementation of the offsets and develop additional criteria for medium-duty truck imports. For now, USMCA-compliant medium-duty vehicles will be exempt from the new duties. The order also extends the 3.75% annual duty offset to automakers with U.S. assembly operations through 2030, reflecting the close integration between passenger vehicle and truck supply chains.
In a parallel move, the administration has given Commerce authority to reduce existing 50% tariffs on steel and aluminum by up to half for companies that manufacture in Canada or Mexico and supply U.S.-based vehicle producers. To qualify, imports must meet USMCA origin requirements and be smelted or cast within North America.
These actions collectively represent one of the most far-reaching trade recalibrations in North American vehicle manufacturing since 2018. According to trade data, the U.S. imported more than $35 billion in medium- and heavy-duty trucks and parts in 2024, primarily from Mexico, Canada, and Europe. Industry analysts note that the measures could compress short-term margins for OEMs while accelerating investment in U.S.-based assembly and parts localization.
A Turning Point for Regional Production Strategy
The tariff order reflects a broader truth about North American manufacturing: incentives are now shifting from cost efficiency to control and resilience. As companies weigh where to assemble vehicles and source components, proximity to final markets may soon carry as much weight as labor or logistics costs. For many manufacturers, these new trade rules will serve not just as a penalty, but as a prompt to redesign supply networks for a more volatile global economy.
