The Future of Commercial Vehicles: Understanding New U.S. Tariffs
The commercial vehicle industry is dynamic, constantly adapting to new technologies, market demands, and regulatory shifts. In a major development, the U.S. government has formally enacted new commercial vehicle tariffs impacting medium- and heavy-duty vehicles, parts, and buses, stemming from the national security protections of Section 232 of the Trade Expansion Act. With the duties taking effect on November 1, 2025, understanding these changes is crucial for fleet managers, procurement officers, and businesses that rely on commercial transportation for future planning.
At Model 1 Commercial Vehicles, we believe in keeping our partners informed. This article will break down the key aspects of these new tariffs to help you navigate the evolving landscape.
What’s Changing? A Snapshot of New Tariffs
The core of the announcement involves specific tariffs on imported vehicles and components:
- Medium- and Heavy-Duty Trucks (Class 3-8) & Parts: A 25% ad valorem duty will be imposed, effective November 1, 2025. The tariff applies to commercial trucks and tractors classified in Classes 4 through 8, as well as some Class 3 vehicles.
- Buses (School, Transit, Motor Coaches): A 10% ad valorem duty will be imposed, also effective November 1, 2025.
These tariffs, based on a finding that imports threaten U.S. national security, aim to foster domestic production and bolster the U.S. commercial vehicle manufacturing base.
Diving Deeper: Trucks and Truck Parts
The 25% tariff on Class 3-8 trucks and their parts introduces nuances based on origin and content:
- Non-USMCA Compliant Trucks: For medium- and heavy-duty trucks that do not qualify for preferential tariff treatment under the United States-Mexico-Canada Agreement (USMCA), the 25% tariff will apply to the full value of the vehicle.
- USMCA-Compliant Trucks: If a truck qualifies under USMCA, the 25% tariff will apply exclusively to the value of the non-U.S. content within the vehicle. The Commerce Department will establish the process for determining this value.
- Truck Parts: The 25% tariff will specifically target key parts, including engines, transmissions, tires, and chassis.
- USMCA-Compliant Truck Parts: USMCA-compliant parts are currently exempt from the new tariffs. They will only face the 25% duty on their non-U.S. content once the Secretary of Commerce establishes a valuation process.
- Anti-Circumvention Rule: The proclamation specifies that imported “knock-down kits” (vehicles imported in pieces for final U.S. assembly) will be subject to the full 25% tariff regardless of USMCA qualification.
Buses: A Separate Category
While trucks face a 25% tariff, buses will be subject to a 10% tariff on imports, like school buses, transit buses, and motor coaches. This lower rate acknowledges the distinct market and production dynamics of the bus sector. As a leading distributor of the industry, Model 1 is closely monitoring how this will impact the availability and pricing of diverse bus options for our partners.
Incentivizing Domestic Production: The Tariff Offset
A key feature of this update is the incentive for domestic manufacturing. To encourage U.S.-assembled medium- and heavy-duty truck production, a portion of the parts tariffs will be offset. This offset will equal 3.75% of the aggregate value of all trucks assembled in the United States from 2025 through 2030. This figure represents the duty owed when a 25% tariff is applied to 15% of the value of a U.S.-assembled truck.
This incentive aims to make domestic assembly more attractive, potentially stimulating job growth and bolstering the U.S. commercial vehicle manufacturing base. Though these aspirations remain to be validated.
Exclusions and Clarifications
It’s also important to note what these tariffs do not cover:
-
Products subject to these new Section 232 tariffs will not be subject to additional or existing sectoral tariffs on steel, aluminum, copper, automobiles and automobile parts, and lumber.
-
They will also not be subject to reciprocal tariffs or those previously imposed on Canada, Mexico, Brazil, or India.
