Canada is investigating certain China truck and bus tires—no finding has been made
The case concerns a defined group of medium- and heavy-vehicle tires. It does not cover all tires from China, and opening an investigation is not a legal finding or a new duty.
Direct answer: CBSA began dumping and subsidy investigations on August 31, 2026, and published its initiation Statement of Reasons on September 15. CITT opened preliminary injury inquiry PI-2026-005 on September 1. The investigations remain underway: the reviewed official record does not show a preliminary injury determination, CBSA preliminary determination or newly imposed provisional duty in this case.
Which tires are described?
New or retreaded pneumatic rubber tires suitable for trucks, buses, trailers and other medium or heavy vehicles, with nominal rim diameters of 17.5, 19.5, 22.5 or 24.5 inches or nominal metric equivalents. The wording includes tube-type or tubeless, radial or non-radial tires, whether or not mounted on wheels or rims, originating in or exported from China.
A qualifying 22.5-inch radial truck tire or 19.5-inch retreaded bus tire could fit the wording. An ordinary passenger-car tire outside the stated suitability and rim-size description does not. Product details—not a broad “tire” label—control.

Questions about the inquiry
Have new duties been imposed?
Not by the initiation events or September 15 Statement of Reasons reviewed here. Provisional duties may arise only at a later stage if the required determinations are made.
Has dumping, subsidization or injury been proven?
No. CBSA is investigating allegations; CITT is separately considering whether there is a reasonable indication of injury, retardation or threat of injury.
Which body decides what?
CBSA investigates dumping and subsidy. CITT conducts the preliminary injury inquiry.
Are ordinary passenger-car tires covered?
The stated goods are tires suitable for named medium and heavy vehicles in four rim sizes. Do not treat passenger tires outside that description as subject goods.
Can exclusions be requested now?
No. CITT says product-exclusion requests are not considered during a preliminary injury inquiry. A later final inquiry, if reached, would have its own process.
