US ITC Vote Paves Way for Duties on Imported Trailers from Canada, China, and Mexico

The U.S. International Trade Commission (ITC) on September 25, 2026, issued a final affirmative injury determination, confirming that dumped and subsidized van-type semi-trailers from Canada, China, and Mexico are harming the U.S. industry. This decision allows the U.S. Department of Commerce to impose final duties on these imports. The ruling follows the Commerce Department's earlier findings of dumping and subsidies from China, which could result in duties exceeding 260%.

The American Trailer Manufacturers Coalition (ATMC) welcomed the ITC's decision, stating it addresses years of lost market share to unfairly traded imports and creates a more level playing field for domestic manufacturers and their workers.

The ATMC filed petitions with the ITC and the Commerce Department in November 2025, citing unfair pricing practices for trailers imported from Canada, China, and Mexico. Final duties for Chinese imports, including subassemblies and trailer kits transshipped through Canada, are expected to be issued by the Commerce Department in October.

Further final determinations for Canada and Mexico by the ITC are anticipated in early 2027. Following these, the Commerce Department will also impose duties on imports from those countries. The resulting duty orders will be in effect for at least five years and are subject to annual reviews. The ATMC stated it will monitor the market for any signs of duty evasion.

The ATMC represents U.S. manufacturers such as Great Dane LLC, Stoughton Trailers LLC, and Wabash Corporation. The U.S. trailer industry directly supports nearly 10,000 jobs and indirectly supports approximately 50,000 more.
