New Tariffs Target Subsidized Chassis From Mexico and Thailand

## 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.

## Abstract

Based on affirmative final determinations by the U.S. Department of Commerce (Commerce) and U.S. International Trade Commission (ITC), Commerce is issuing countervailing duty (CVD) orders on certain chassis and subassemblies thereof (chassis) from Mexico and the Kingdom of Thailand (Thailand).

Commerce instructed CBP to li…
