US Imposes Anti-Dumping Duties on Thai Chassis & Subassemblies
The U.S. Department of Commerce has issued a final affirmative determination that certain chassis and subassemblies thereof from Thailand are being sold in the United States at less than fair value (LTFV), covering the investigation period of January 1–December 31, 2024. This anti-dumping finding will result in duties imposed on affected imports. Shippers and importers of chassis and related subassemblies from Thailand should expect additional landed costs and compliance requirements when clearing these goods through U.S. customs.

The U.S. Department of Commerce has determined that certain chassis and subassemblies thereof from Thailand are being, or are likely to be, sold in the United States at less than fair value (LTFV). The investigation covered the period from January 1, 2024, through December 31, 2024.
"The U.S. Department of Commerce (Commerce) determines that certain chassis and subassemblies thereof (chassis) from Thailand are being, or are likely to be, sold in the United States at less than fair value (LTFV)."
This final affirmative determination triggers anti-dumping duties on the affected product category. Chassis—which form the structural base of vehicles and machinery—and their subassemblies are subject to the measure when imported from Thailand.
Who Is Affected
Importers, distributors, and manufacturers sourcing chassis or chassis subassemblies from Thai suppliers will face anti-dumping duties on entries. This applies to both direct importers and freight forwarders arranging shipments of these goods into the United States. The duties are retroactive to the investigation period and will apply to future shipments as well.
The HS classification for chassis typically falls within Chapter 87 (vehicles and parts thereof), though specific subassemblies may fall under related chapters depending on their composition and application. Importers should verify the precise HS code for their specific product with their customs broker or classification specialist, as some components may warrant different treatment.
Compliance and Next Steps
Importers must ensure their entries properly declare the Thai origin and applicable HS codes. Customs brokers should flag these shipments for potential duty assessment. The Commerce Department's final determination establishes the basis for U.S. International Trade Commission (ITC) duties that will be imposed on subject merchandise.
Shippers and importers should review their supply chains and cost structures immediately. Anti-dumping duties are typically assessed as a percentage of the entered value and will increase the total landed cost of Thai chassis and subassemblies entering the U.S. market. Consider alternative sourcing, price adjustments, or product redesign if feasible.
