New Section 232 Investigation: Medium- and Heavy-Duty Trucks and Parts
On April 24, 2025, the U.S. Department of Commerce initiated a new national security investigation under Section 232 of the Trade Expansion Act of 1962 into imports of medium-duty trucks, heavy-duty trucks, and related parts and derivative products.
Scope of Investigation:
- Medium-duty trucks: trucks with a gross vehicle weight of more than 10,000 and under 26,001 pounds.
- Heavy-duty trucks: trucks with a gross vehicle weight rating of 26,001 pounds or more.
- Medium- and heavy-duty truck parts: components and systems, including engines and engine parts, transmissions and powertrain parts, and electrical components.
Request for Public Comments:
The Commerce Department is seeking written comments from interested parties on issues including:
- Domestic demand for trucks and parts
- Reliance on foreign supply chains
- Risks from import concentration
- Effects of foreign subsidies and unfair trade practices
- Expansion of U.S. production capacity
- Whether additional measures are necessary to protect national security
A full list of issues under review can be found in the Federal Register notice linked below.
Member Feedback
We encourage members who are impacted by potential tariffs or other trade actions on medium- and heavy-duty vehicles and parts to provide feedback to the Auto Care Association for inclusion in our industry comments. We also encourage members to submit their own comments so that individual business impacts are fully represented in the public record.
The deadline for written comments is June 10, 2025.
