US finds China dumped subsidised trailers, sets duties above 130%
Synopsis
Washington has hit Chinese van-type trailers with provisional duties exceeding 130% after finding both heavy subsidisation and below-fair-value dumping. With CIMC having walked away from the investigation and adverse inferences applied, the final rates are among the steepest in recent US trade actions against China — and a permanent order now hinges on a single ITC injury ruling due within 45 days.
Key Takeaways
The US Commerce Department found Chinese van-type trailers subsidised at 134.75% and dumped at a margin of 130.86% .
The antidumping cash-deposit rate, after subsidy adjustment, was set at 129.73% .
CIMC Baowell Industries and Qingdao CIMC Reefer Trailer were named as principal respondents; CIMC withdrew before verification, triggering an adverse inference ruling.
The scope covers van-type trailers over 26,000 pounds and key subassemblies, including parts routed through Canada .
The US International Trade Commission must deliver an injury finding within 45 days for duties to become permanent.
Determinations are scheduled for publication in the Federal Register on 31 August 2025 .
The US Commerce Department has concluded that Chinese van-type trailers were heavily subsidised and sold in the American market below fair value, paving the way for steep trade duties pending a final injury ruling. The determinations, set to be published in the Federal Register on 31 August 2025, mark a significant escalation in Washington's scrutiny of Chinese commercial vehicle exports.
Key Determinations
Commerce calculated a countervailable subsidy rate of 134.75% for Chinese producers and exporters, finding that financial contributions from Chinese government authorities had conferred specific benefits on the industry. Separately, it determined a China-wide dumping margin of 130.86%, with the corresponding antidumping cash-deposit rate — adjusted for export subsidies — set at 129.73%.
The subsidy investigation covered the period from January through December 2024, while the dumping inquiry examined sales made between April and September 2025.
Scope of the Investigation
The findings apply to large enclosed van-type trailers weighing more than 26,000 pounds, along with a broad range of finished and unfinished subassemblies. Covered components include trailer frames, walls, roofs, doors, landing gear, axle assemblies, brakes, electrical systems, wheels, and refrigeration units.
Notably, the investigation also covers Chinese trailer parts routed through Canada. Commerce clarified that processing or assembling the merchandise in a third country does not automatically exclude it from the duties. Importers of Chinese subassemblies must use specially established third-country case numbers, with duties applying only to the Chinese-origin portion and accompanying components.
What Happened With Principal Respondents
CIMC Baowell Industries and Qingdao CIMC Reefer Trailer were selected as the principal respondents in the subsidy investigation. However, CIMC withdrew from participation before the verification stage, prompting Commerce to rely on available information and apply an adverse inference in determining the final subsidy rate — a standard procedure when a respondent fails to cooperate fully.
US Customs and Border Protection has already been directed to suspend final processing of covered Chinese imports and collect provisional cash deposits.
What Comes Next
The trade action is not yet complete. The US International Trade Commission (ITC) must decide within 45 days whether the American trailer industry has suffered material injury — or faces a credible threat of injury — as a result of the Chinese imports. Only if the ITC finds affirmative injury will the duties become permanent. This comes amid a broader pattern of US trade actions targeting Chinese manufacturing sectors, from steel and solar panels to now commercial transport equipment.
Point of View
Particularly after CIMC's mid-investigation withdrawal forced an adverse inference. The Canada routing provision is the detail most likely to be tested in court: it signals Washington is closing the transshipment loophole that has blunted earlier trade actions. The real question is whether the ITC injury finding holds up; US trailer manufacturers will need to demonstrate concrete harm, not just price pressure, to lock in what would be one of the steepest permanent duty orders on Chinese transport equipment in recent memory.

Frequently Asked Questions
What did the US Commerce Department find about Chinese trailers?
Commerce concluded that Chinese van-type trailers were both heavily subsidised — at a countervailable rate of 134.75% — and sold below fair value, with a dumping margin of 130.86%. The findings cover large enclosed trailers and a wide range of subassemblies used in freight transport.
When do the new trailer duties take effect?
Provisional cash deposits are already being collected by US Customs and Border Protection. The formal determinations are scheduled for publication in the Federal Register on 31 August 2025, making them officially applicable from that date.
Why were such high duty rates applied to CIMC?
CIMC Baowell Industries and Qingdao CIMC Reefer Trailer were selected as principal respondents but CIMC withdrew before the verification stage. Commerce responded by applying an adverse inference — a legal mechanism that assumes the worst-case scenario when a party refuses to cooperate — resulting in the elevated final rates.
Are Chinese trailers assembled in Canada also covered?
Yes. The investigation explicitly covers Chinese trailer parts routed through Canada. Importers of such subassemblies must use specially established third-country case numbers, and duties apply to the Chinese-origin portion of the goods regardless of where final assembly occurs.
What happens next before duties become permanent?
The US International Trade Commission must determine within 45 days whether the American trailer industry has suffered material injury or faces a threat of injury from the Chinese imports. A positive finding is required for the duties to be made permanent; a negative finding would terminate the orders.
