CBSA initiates dumping and subsidy investigations into Chinese truck and bus tires covering a $1.2 billion Canadian market
Executive Summary
The Canada Border Services Agency (CBSA) launched investigations on August 31, 2026 into alleged dumping and subsidization of truck and bus tires imported from China. The Canadian International Trade Tribunal (CITT) will issue a preliminary injury decision by October 30, 2026. The CBSA will follow with preliminary dumping and subsidy decisions by November 30, 2026.
Bottom Line
The CBSA's August 31, 2026 investigation covers alleged dumping and subsidization of Chinese-origin truck and bus tires in a Canadian market the source estimates at approximately $1.2 billion annually. The CITT issues its preliminary injury decision by October 30, 2026, and the CBSA issues its preliminary dumping and subsidy decisions by November 30, 2026. Cresthaven reading: importers of record for Chinese truck and bus tires into Canada sit directly inside the investigation's scope and face potential provisional duty exposure contingent on affirmative preliminary findings at both the CBSA and CITT stages.
Key Regulatory Signals
- Dual-Track Investigation Opens: The CBSA is investigating whether Chinese-origin truck and bus tires are sold at unfair prices, subsidized, or both. The CITT will begin a parallel preliminary inquiry into whether those imports are harming Canadian producers, with its decision due by October 30, 2026.
- CBSA Preliminary Decisions Due November 30, 2026: The CBSA's preliminary dumping and subsidy determinations are due by November 30, 2026. Cresthaven reading: importers of Chinese truck and bus tires into Canada face the prospect of provisional anti-dumping and countervailing duties if the CBSA's preliminary findings are affirmative.
- Complainants Represent Majority of Canadian Production: The complaint was filed by the Canadian Retread Manufacturers Association and Michelin North America (Canada) Inc. The source states these complainants represent the majority of Canadian production of truck and bus tires, covering a market estimated at approximately $1.2 billion annually.
- Stated Injury Allegations Are Broad: The complainants allege material injury in the form of price undercutting, price suppression, lost sales, lost volumes, reduced market share, lower capacity utilization, reduced employment, reduced profitability, and negative impact on investments.
- Statement of Reasons Forthcoming: The CBSA has announced that a statement of reasons with additional investigation details will be available on its website within 15 days from the August 31, 2026 launch date.
Regulatory Delta
- In 2025, the CBSA launched 33 combined dumping and subsidy investigations covering 9 products; 28 resulted in anti-dumping and countervailing duties imposed for five years. This tire investigation is one of 16 combined investigations for 8 products initiated so far in 2026. - The source estimates the relevant market at approximately $1.2 billion annually. - The CITT's preliminary inquiry runs concurrently with the CBSA investigation, reflecting the standard bifurcated structure of Canada's trade remedy system under the Special Import Measures Act.
Materiality Classification
MEDIUM — Active CBSA trade-remedy investigation covering a $1.2 billion Canadian market with defined preliminary decision deadlines; importers of Chinese truck and bus tires must assess exposure to potential provisional duties, but no measures are yet in force and the investigation remains at the initiation stage.
