China will impose anti-dumping duties on halogenated butyl rubber imports from Japan and Canada starting March 14, 2026, following a final ruling by the Ministry of Commerce. The measures aim to address material injury caused to domestic producers due to dumped products, with duties ranging from 13.8% to 30.1% for affected companies.
The decision concludes an investigation launched in September 2024, which found evidence of dumping by Japanese and Canadian firms. A preliminary ruling in August 2025 confirmed the link between these practices and harm to China’s domestic industry. The probe into imports from India was terminated earlier.
Halogenated butyl rubber is critical for manufacturing tubeless tires, pharmaceutical stoppers, and industrial materials. The duties will remain in effect for five years, impacting trade dynamics in a sector vital to automotive and manufacturing supply chains.
Analysts suggest the move reflects China’s commitment to enforcing fair trade practices while safeguarding its industrial base. Businesses reliant on these imports are advised to assess supply chain adjustments as the measures take effect.
