Government Shutdown Delays Investigation Into Suspiciously Cheap Foreign Trailer Parts
Published Date: 12/15/2025
Notice
Summary
The U.S. is checking if cheap chassis and parts from Mexico, Thailand, and Vietnam are hurting American businesses. They’re wrapping up investigations to decide if extra taxes should be added to these imports. This could affect importers and manufacturers soon, with key decisions expected by late September 2025.
Analyzed Economic Effects
3 provisions identified: 0 benefits, 0 costs, 3 mixed.
Preliminary finding: LTFV and subsidies
The Department of Commerce preliminarily found that chassis and subassemblies from Mexico, Thailand, and Vietnam are being sold in the U.S. at less-than-fair-value, and that products from Mexico and Thailand are subsidized. These preliminary findings are the reason the Commission has scheduled a final phase investigation to assess injury to U.S. industry.
Final determination scheduled for Sept. 29, 2025
The final phase of the antidumping and countervailing duty investigations is scheduled with a key date of September 29, 2025. That is the date noted in this notice for the Commission's final-phase scheduling related to these investigations.
Which chassis parts are in scope
The investigations cover chassis and subassemblies provided for in HTSUS subheadings 8716.39.00 and 8716.90.50, including chassis frames, running gear/axle assemblies, and connecting assemblies. The scope explicitly excludes dry van trailers, refrigerated van trailers, and flatbed trailers.
