Thailand's Cheap Chassis Faces U.S. Duty Wallop
Published Date: 4/24/2026
Notice
Summary
The U.S. Department of Commerce found that certain chassis and parts from Thailand are being sold in the U.S. for less than their fair price. Starting April 24, 2026, importers might face extra duties to level the playing field for American businesses. This means companies importing these parts should get ready for new costs and rules soon!

Analyzed Economic Effects
5 provisions identified: 0 benefits, 3 costs, 2 mixed.
High Antidumping Cash Deposit Rates
Commerce found final dumping margins for certain chassis from Thailand and set cash deposit rates of 72.85 percent for Dee Siam and all other producers/exporters, and 129.63 percent for Panus (the Panus rate is based on adverse facts available). These rates apply if Commerce issues an antidumping (AD) order and will be required as cash deposits on affected imports.
Adverse Facts Available Raised Panus Rate
Commerce applied adverse facts available (AFA) to Panus Assembly Co., Ltd. and assigned a dumping margin of 129.63 percent to Panus, as stated in the final determination.
Which Chassis Parts Are Covered or Excluded
The investigation covers finished and unfinished chassis and many subassemblies for carriage of containers or other payloads (e.g., chassis frames, running gear assemblies, axle assemblies, and related assemblies). 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), and certain axle subassemblies meeting specified size and lug requirements.
Suspension of Liquidation Dates for Entries
Commerce instructed U.S. Customs and Border Protection to suspend liquidation of subject merchandise entered, or withdrawn from warehouse, for consumption on or after September 29, 2025. Commerce directed CBP to discontinue suspension for entries on or after March 28, 2026, but to continue suspension for entries on or before March 27, 2026.
ITC Injury Decision and Refund Rule
Commerce will notify the U.S. International Trade Commission (ITC) of this final affirmative LTFV determination; the ITC has up to 45 days after this final determination to decide whether U.S. industry is materially injured. If the ITC finds no injury, the proceeding is terminated, suspension of liquidation is lifted, and any cash deposits will be refunded.
