US anti-dumping probe finds Chinese van trailers undersold
The U.S. Department of Commerce has issued a preliminary affirmative determination that van-type trailers and subassemblies from China are being sold in the United States at less than fair value (LTFV), triggering an anti-dumping investigation. The investigation period covers April 1 through September 30, 2025. Interested parties can submit comments on the preliminary finding, which may lead to provisional duties pending a final determination.

On June 15, 2026, the U.S. Department of Commerce issued a preliminary affirmative determination that van-type trailers and subassemblies thereof from the People's Republic of China are being, or are likely to be, sold in the United States at less than fair value (LTFV). This triggers a formal anti-dumping investigation under U.S. trade remedy law.
Scope and timing
The investigation covers van-type trailers and subassemblies thereof, including component parts and finished units. The period of investigation (POI) is April 1, 2025, through September 30, 2025. This preliminary finding is the first stage in the anti-dumping process; a final determination from Commerce is expected within months.
Van-type trailers typically fall within HS Chapter 87 (vehicles and related parts), and this investigation may affect importers, manufacturers, and freight operators relying on Chinese trailer sources.
What happens next
The Commerce Department's preliminary affirmative determination means that:
- Provisional duties may be imposed on entries of the subject merchandise during the remainder of the investigation.
- Interested parties (importers, foreign exporters, domestic producers, and industry associations) have the right to submit factual and legal comments on the preliminary determination.
- A final determination is expected within approximately six months of the preliminary ruling.
- If Commerce makes a final affirmative determination, the U.S. International Trade Commission (ITC) will conduct its own injury investigation to determine whether a U.S. industry is materially injured or threatened with injury.
Why this matters
Anti-dumping investigations are trade remedies designed to prevent foreign suppliers from selling goods at artificially low prices and injuring domestic competitors. A preliminary finding of LTFV signals Commerce's initial assessment that Chinese manufacturers or exporters have priced van-type trailers below their cost of production or home-market prices.
What this means for shippers
Importers of van-type trailers and subassemblies from China face immediate uncertainty: provisional anti-dumping duties could apply to shipments during the investigation period and beyond if a final determination affirms the preliminary finding. Update landed-cost estimates to account for potential provisional duties, monitor Commerce announcements for duty rates, and review your supply contracts for force-majeure or price-adjustment clauses. Check the anti-dumping database regularly and file comments if your business is affected.
