US imposes countervailing duties on Mexican chassis
The U.S. Department of Commerce has made a final affirmative determination that countervailable subsidies are being provided to producers and exporters of certain chassis and subassemblies from Mexico, effective as of April 24, 2026. The investigation period covered January 1–December 31, 2024. This duty will apply to shipments of affected chassis and sub-assemblies entering the United States, increasing landed costs for importers and freight forwarders sourcing these components from Mexico.

On April 24, 2026, the U.S. Department of Commerce issued a final affirmative countervailing duty determination against certain chassis and subassemblies thereof from Mexico. The investigation period covered January 1 through December 31, 2024.
What triggered the investigation
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 Mexico.
Countervailing duties are imposed when a foreign government subsidizes the production or export of goods sold to the United States, distorting fair competition and injuring domestic producers.
Who is affected
This determination affects any U.S. importer, freight forwarder, or 3PL sourcing chassis or chassis subassemblies from Mexico. Manufacturers in the automotive sector—including truck and trailer builders, equipment OEMs, and parts distributors—will see countervailing duties applied at the border when these goods enter the U.S. The exact duty rate and product scope are specified in the full Federal Register notice.
Mexican exporters and their U.S. customers should expect:
- Increased landed costs on all qualifying chassis and sub-assemblies
- Possible retroactive duties on entries made during the investigation period
- Requirements to revise pricing and landed-cost estimates for ongoing supply chains
Next steps
The International Trade Commission (ITC) will also conduct a final injury determination. If the ITC finds that U.S. industry has been materially injured by such subsidized imports, the countervailing duties will remain in place. Importers should monitor ITC announcements and consult tariff classification specialists to confirm whether specific chassis products fall under the scope of this order.
What this means for shippers
Countervailing duties raise the true cost of goods and require accurate landed-cost modeling. Review your Mexican chassis sourcing and update duty estimates immediately.
