US imposes anti-dumping duties on Vietnamese chassis
The U.S. Department of Commerce has issued a final affirmative determination that certain chassis and subassemblies from Vietnam are being sold in the United States at less than fair value. This anti-dumping finding, covering the investigation period of July 1–December 31, 2024, will result in the application of anti-dumping duties on imports of these products. Shippers exporting or importing chassis and related subassemblies from Vietnam should expect increased landed costs and compliance requirements when clearing these goods through U.S. customs.

On April 24, 2026, the U.S. Department of Commerce published a final affirmative determination that certain chassis and subassemblies thereof from Vietnam are being sold in the United States at less than fair value (LTFV). This determination triggers anti-dumping duty investigations and will result in the imposition of anti-dumping measures on affected imports.
Investigation Scope and Timeline
The investigation period covered July 1, 2024, through December 31, 2024. The Department of Commerce's finding indicates that Vietnamese manufacturers and exporters have engaged in dumping—selling products in the U.S. market below their home-market or constructed value.
Who Is Affected
Shippers, freight forwarders, and e-commerce merchants importing chassis and subassemblies thereof from Vietnam will be directly impacted. This includes:
- Direct importers of chassis products
- Original equipment manufacturers (OEMs) purchasing chassis components
- Logistics providers coordinating shipments of these goods
- Suppliers in the automotive and equipment manufacturing sectors
The final determination means that upon entry into the United States, shipments of these products will be subject to anti-dumping duties in addition to normal tariffs. The specific duty rates will be determined through subsequent Commerce Department proceedings and will depend on individual company investigations.
Implications for Landed Cost
Importers must now account for anti-dumping duties when calculating landed costs. These duties are assessed as a percentage of the transaction value and will increase the overall cost of importing Vietnamese chassis and subassemblies. The exact duty margins may vary by exporter and will be published in forthcoming antidumping duty orders.
Shippers should:
- Review their current Vietnamese chassis supplier relationships
- Recalculate landed cost estimates to include anticipated anti-dumping duties
- Consider alternative sourcing strategies or supplier diversification
- Ensure proper HS classification and valuation documentation to support duty assessments
- Monitor the Federal Register for the issuance of the antidumping duty order and any company-specific duty rates
What this means for shippers
Anti-dumping determinations increase compliance complexity and landed costs for affected product categories. Understanding the full financial impact on your supply chain is essential. Use landed cost estimation tools to model the effect of these new duties on your pricing and margins before placing orders.
