US Imposes Countervailing Duties on Thai Chassis Imports
The U.S. Department of Commerce has determined that certain chassis and subassemblies exported from Thailand are receiving countervailable subsidies, triggering the imposition of countervailing duties. The determination covers products manufactured during the investigation period of January 1–December 31, 2024. This action affects importers and manufacturers sourcing chassis components from Thai suppliers, who will now face additional duties on these shipments.

On April 24, 2026, the U.S. Department of Commerce issued a final affirmative countervailing duty (CVD) determination against certain chassis and subassemblies thereof from the Kingdom of Thailand. The decision confirms that countervailable subsidies are being provided to producers and exporters of these products, triggering the imposition of additional duties on imports.
Who Is Affected
The determination applies to chassis and subassemblies exported from Thailand during the period of investigation (POI), which runs from January 1, 2024, through December 31, 2024. Importers, freight forwarders, and manufacturers sourcing these products from Thai suppliers will be directly affected by the new duties.
"The U.S. Department of Commerce (Commerce) determines that countervailable subsidies are being provided to producers and exporters of certain chassis and subassemblies thereof (chassis) from the Kingdom of Thailand (Thailand)."
What This Means for Shippers
Countervailing duties are imposed to offset subsidies provided by foreign governments to their exporters. When duties are assessed, the landed cost of Thai-origin chassis imports increases substantially, affecting pricing, margin calculations, and competitive positioning for U.S. importers.
Shippers and importers must now ensure that Thai chassis and subassemblies are properly classified, valued, and declared to U.S. Customs and Border Protection. Accurate HS classification and proper valuation are critical to correctly calculating CVD liability. Misclassification or undervaluation can result in significant penalties and duties owed upon liquidation.
For those importing these products, it's essential to review supplier documentation, understand the subsidy findings, and adjust cost estimates to account for the new duties. Consider consulting with customs brokers or trade advisors to ensure compliance and to explore potential remedies, such as suspension agreements or reviews of the determination.
