China will impose anti-dumping tariffs of up to 30.1% on halogenated butyl rubber imported from Canada and Japan, the Chinese Commerce Ministry said on Friday, in a final ruling for investigations launched in 2024.

Imports from Canada will face anti-dumping duties of 13.8%, while those from Japan, except Japan Butyl, will be charged a 30.1% rate, the ruling showed. Japan Butyl will face an anti-dumping rate of 15%.

Halogenated butyl rubber is used in various items, including tire linings, hoses and pharmaceutical products.

Investigators issued a “final determination” on Friday, concluding that the Chinese industry “has suffered material injury, and that a causal link exists (with) the dumping,” the Commerce Ministry said.

The tariffs are effective from Saturday and will be in place for five years, the ministry said.
