US Finds Mexico Chassis Imports Sold Below Fair Value
The U.S. Department of Commerce issued a final affirmative determination that imports of certain chassis and subassemblies from Mexico are being sold at less than fair value (LTFV) during the investigation period of January 1–December 31, 2024. This anti-dumping finding typically triggers countervailing duties on affected shipments. Exporters and importers of chassis components from Mexico should expect duty assessments and possible retroactive application to entries during the POI.

The U.S. Department of Commerce announced a final affirmative determination on April 24, 2026, that certain chassis and subassemblies thereof imported from Mexico are being, or are likely to be, sold in the United States at less than fair value (LTFV). The investigation covered the period January 1, 2024, through December 31, 2024.
Who is affected
This determination applies to shipments of chassis and their subassemblies manufactured in Mexico and exported to the United States. Mexican producers and exporters, as well as U.S. importers purchasing these components, will face anti-dumping duties on entries covered by the investigation period.
What happens next
An affirmative LTFV determination typically leads to the imposition of anti-dumping duties calculated on a country-wide or company-specific basis. The Commerce Department will likely publish a notice of final determination with specific duty margins, and the U.S. International Trade Commission (ITC) will conduct a separate injury investigation to determine whether domestic industry has been materially injured or threatened with material injury.
Importers with entries during the POI (January 1–December 31, 2024) may face retroactive liability for duties. Importers should review their landed cost calculations and reconcile any entries made during this window with customs brokers and freight forwarders.
HS classification
Chassis and their subassemblies typically fall under HS Chapter 87 (vehicles and parts thereof), though specific product codes depend on composition and function. Importers should verify the precise HS classification of their shipments with their customs broker.
What this means for shippers
This anti-dumping determination increases the cost of importing Mexican chassis and subassemblies. Shippers and freight forwarders should:
- Recalculate landed costs for affected shipments
- Review entries made between January 1 and December 31, 2024, for potential duty liability
- Monitor the Federal Register for the final duty margin notice
- Consider alternative sourcing if duty rates are prohibitive
