New Tariffs Target Subsidized Chassis From Mexico and Thailand
Published Date: 6/18/2026
Notice
Summary
Starting June 18, 2026, the U.S. is adding extra taxes (called countervailing duties) on certain vehicle chassis and parts imported from Mexico and Thailand. This move helps U.S. manufacturers who were hurt by unfair government subsidies in those countries. Importers will now pay more, making things fairer and protecting American jobs.
Analyzed Economic Effects
5 provisions identified: 1 benefits, 3 costs, 1 mixed.
Countervailing Duties Reinstated June 18, 2026
On June 18, 2026, Commerce issued countervailing duty (CVD) orders on certain chassis and subassemblies from Mexico and Thailand and directed U.S. Customs and Border Protection to reinstitute suspension of liquidation. CBP will assess CVDs and require cash deposits at the time importers normally deposit estimated duties, with assessment applying to unliquidated entries entered or withdrawn for consumption on or after August 1, 2025 (subject to the provisional-measures exception described elsewhere).
Very High Duties on Mexican Chassis
For chassis from Mexico, Commerce set an ad valorem countervailable subsidy rate of 76.91 percent for listed Mexican producers and for 'All Others.' Importers of subject Mexican chassis must pay cash deposits and duties at this 76.91% rate when the CVD orders are enforced.
Moderate Duties on Thai Chassis
For chassis from Thailand, Commerce set ad valorem countervailable subsidy rates of 10.72% for Dee Siam Manufacturing Co., Ltd., 9.65% for Panus Assembly Co., Ltd., and a 10.50% 'All Others' rate. Importers of subject Thai chassis must pay cash deposits and duties at these rates when the CVD orders are enforced.
Provisional-measures Exception Window
Entries of subject chassis made on or after November 29, 2025 and prior to the publication of the ITC's final determinations in the Federal Register are not subject to countervailing duties because the provisional suspension of liquidation expired on November 29, 2025. Commerce instructed CBP to liquidate those entries without regard to CVDs.
What Products Are Covered or Excluded
The orders cover finished and unfinished chassis and many subassemblies for road, marine RORO, and rail transport, and list typical components and subassemblies that make a chassis subject merchandise. The scope explicitly excludes dry van trailers, refrigerated van trailers, flatbed trailers, certain fully assembled small trailers (gross axle weight rating of 8,000 lbs or less with specified coupling), and fully dressed axle subassemblies meeting certain small-size criteria.
