Commerce sets preliminary duties on Mexican, Canadian trailers
Written by Nicholas Bell
The US Department of Commerce issued preliminary antidumping determinations covering van-type trailers and certain subassemblies from Mexico and Canada, directing US Customs and Border Protection to begin collecting cash deposits on covered imports.
The determinations took effect Aug. 4, finding that producers in both countries sold, or were likely to sell, covered products in the US at less than fair value. Commerce based its preliminary findings on sales made from Oct. 1, 2024, through Sept. 30, 2025.
Mexico represents the larger of the finished trailer trade flow. Census Bureau data compiled by Global Trade Tracker show that Mexico supplied more than 98% of US imports under HTS subheading 8716.39.0040 during the five-year period ending with the latest available June data. Commerce identified that classification as one under which covered van-type trailers and semi-trailers typically enter the US.
Mexico cash deposit rates reach 79.92%
Commerce calculated a 10.19% weighted-average dumping margin for Hyundai de Mexico S.A. de C.V. After accounting for a countervailing duty offset, the company received a preliminary cash deposit rate of 8.35%.
Utility Trailer Manufacturing de México S. de R.L. de C.V. received a 3.21% dumping margin and a subsidy-adjusted cash deposit rate of 2.43%.
Commerce calculated an 8.72% dumping margin for all other Mexican exporters and set the corresponding cash deposit rate at 7.10%.
Five Mexican producers or exporters received preliminary rates of 79.92% after they did not respond to Commerce’s quantity and value questionnaire. The companies are Nimmka S.A. de C.V., which does business as Atro Remolques y Carrocera; BRD Trailers S.A. de C.V., which does business as DeLucio; Gallegos Trailers; Industria Kuzzy de Mexico S.A. de C.V.; and Manufacturas Industriales Gami S.A. de C.V.
Commerce based those rates on adverse facts available after finding the companies withheld requested information and did not meet agency deadlines. The department adjusted several deposit rates to account for export subsidies identified in the related countervailing duty investigation.
Mexico also accounted for about 19% of imports under HTS subheading 8716.90.5060 during the same five-year period. That classification covers parts for trailers, semi-trailers and other non-mechanically propelled vehicles. China held a larger share of imports under that category at around 47%, while Canada accounted for about 16%.
Canada receives 4.29% general rate
Commerce calculated a 4.29% dumping margin for Manac Inc. and assigned the same rate to the all other potential exporters not specified elsewhere. Di-Mond Sales Inc., Innovative Trailer Design Industries Inc. and Morgan Canada Corp. also received preliminary rates of 4.29%.
Collins Manufacturing Co. and GINCOR Werx received rates of 44.86% after they did not respond to Commerce’s quantity and value questionnaire.
Commerce did not calculate a separate Canadian margin for Vanguard Refrigerated Trailer Co. Ltd. The department found trailers the company shipped from Canada during the investigation period consisted of Chinese-origin merchandise covered by the separate antidumping and countervailing duty investigations involving China.
Commerce stated Chinese trailers and subassemblies processed in or shipped through Canada may remain subject to the China cases. For trailers containing covered Chinese subassemblies, only the Chinese portion may face countervailing duties under the related China proceeding.
Scope of coverage
The investigations cover finished and unfinished van-type trailers used to transport goods, including trailers with a gross vehicle weight rating of more than 26,000 pounds.
Covered subassemblies include trailer subframes, wall and roof assemblies, door frames, running gear and landing gear. The scope also includes certain components imported with trailers or subassemblies. Processing or assembly in another country does not automatically remove products from the cases.
The cases began as part of a broader set of trade investigations involving Canada, China and Mexico. Commerce previously issued preliminary antidumping and countervailing duty determinations involving China, along with a preliminary subsidy determination involving Mexico.
Petitioners withdrew their subsidy allegations against Canada, ending that portion of the proceedings.
Final decisions pending
The preliminary findings do not conclude the investigations.
Commerce postponed the final Mexican determination after Hyundai de Mexico requested more time and an extension of provisional measures. The agency also postponed the Canadian final determination following a request from Manac.
In both cases, Commerce may issue its final determination as late as 135 days after publication of the preliminary findings. The provisional measures may remain in place for as long as six months.
If Commerce issues affirmative final determinations, the US International Trade Commission will decide whether the imports materially injure or threaten material injury to the domestic industry.
Affirmative findings from both agencies would result in antidumping duty orders. A negative determination by either agency, Commerce or the International Trade Commission, would end the applicable proceeding, and any collected cash deposits would generally be refunded.
