China's Ministry of Commerce announced preliminary anti-dumping measures targeting imports of halogenated butyl rubber and canola (rapeseed) from Canada, Japan, and India. The ministry will impose temporary anti-dumping deposits on halogenated butyl rubber imports from Canada and Japan starting August 14, 2025, but has terminated its probe into Indian imports due to low volume. Additionally, China will implement a provisional tariff of 75.8% on Canadian canola imports, effective August 14, citing evidence of dumping that harms China's domestic canola oil market. This move escalates the ongoing trade dispute between China and Canada, which began last year following Canadian tariffs on Chinese electric vehicle imports. The tariffs on Canadian canola threaten to shut Canadian farmers out of China, the world's second-largest economy for canola. Canadian trade and agriculture ministers expressed deep disappointment but remain open to engagement with Beijing. The imposition of these tariffs has caused rapeseed meal prices in China to surge by 6%, reflecting supply concerns. Canadian officials have ruled out increasing market access to American farmers as a strategy to mitigate the impact of the tariffs. The dispute adds to existing tensions in agricultural trade between the two countries.
