Commerce Finds China Subsidizing Trailer Imports, Sets Up ITC Injury Vote

The U.S. Department of Commerce has made a final affirmative determination that producers and exporters of van-type trailers from China received countervailable subsidies, according to a notice published in the Federal Register on August 31, 2026. The finding, filed under docket C-570-218, covers trailers made in 2024 and sets an estimated subsidy rate of 134.75 percent ad valorem.

That rate was assigned to CIMC Baowell Industries Co., Ltd. and Qingdao CIMC Reefer Trailer Co., Ltd., the only companies examined individually, as well as to 19 other Chinese manufacturers Commerce listed as "non-responsive" and to all other Chinese exporters, the notice said. Commerce said it applied the rate under "adverse facts available" after CIMC notified the agency on June 5, 2026, that it was withdrawing from the investigation before Commerce could verify its data.

The investigation covers van-type trailers and key subassemblies — including subframes, side walls, roofs, door assemblies, rear impact guards, coupler assemblies, running gear and landing gear — built with a gross vehicle weight rating above 26,000 pounds, according to the scope description in the notice. The duty also reaches components such as brake assemblies, axles, suspensions, wheels, tires and refrigeration units when they are shipped on the same bill of lading as a covered trailer or subassembly.

Commerce said it had already instructed U.S. Customs and Border Protection to collect cash deposits and suspend liquidation of entries covered by the case starting June 5, 2026, the date its preliminary determination was published. The agency noted the countervailing duty case was aligned with a companion antidumping investigation into the same Chinese trailers, though this notice did not disclose the antidumping rate.

Because Commerce's determination is affirmative, the notice said, the agency has notified the ITC, which under Section 705(b) of the Tariff Act of 1930 must decide within 45 days whether the U.S. trailer industry is materially injured, or threatened with injury, "by reason of" the Chinese imports. If the ITC agrees, Commerce will issue a countervailing duty order directing CBP to collect the duties. If the ITC finds no injury, Commerce said the case will be terminated and all cash deposits collected since June 5, 2026, will be refunded.

What it means

For carriers, owner-operators and fleets buying dry van or refrigerated trailers sourced from China, this determination raises the cost floor on those imports if the ITC agrees that domestic producers were harmed. A 134.75 percent cash-deposit rate would apply not just to finished trailers but to major subassemblies and components shipped with them, which could affect buyers who source parts or partially built trailers from Chinese suppliers. Until the ITC rules, deposits continue to be collected but the case remains open, and a negative injury finding would unwind the duty and trigger refunds.

What's next

Commerce's notice says the ITC must issue its injury determination within 45 days of being notified of Commerce's affirmative finding. If the ITC finds injury, Commerce will issue a formal countervailing duty order instructing CBP to begin duty assessment; if not, the proceeding ends and deposits posted since June 5, 2026, are refunded. The notice does not disclose the result or timing of the companion antidumping (less-than-fair-value) investigation into the same Chinese trailers, which was aligned with this case.
