China’s Ministry of Commerce issued a flurry of trade actions on Tuesday, imposing steep provisional duties on Canadian rapeseed and certain rubber products while opening a fresh anti-dumping probe into Canadian pea starch. Beijing said the measures are based on preliminary findings that the goods were sold below fair market value and harmed domestic producers. Importers of Canadian rapeseed will be required to place deposits equal to 75.8% of the cargo’s value from 14 August. The step follows a separate 100% tariff China levied earlier this year on Canadian rapeseed oil and meal, and threatens to further disrupt a trade worth more than US$3 billion annually. For halogenated butyl rubber—used in tires and pharmaceutical stoppers—Chinese customs will collect security deposits of up to 40.5% on shipments from Canada and Japan starting the same date. MOFCOM ended its investigation into Indian rubber on grounds that the country’s exports were too small to affect the market. Separately, the ministry launched an anti-dumping investigation into Canadian pea starch. The inquiry covers imports during 2024 and will run for one year, with a possible six-month extension. MOFCOM said all decisions comply with World Trade Organization rules and are intended to protect domestic industries. The latest moves escalate an already tense trade relationship after Ottawa imposed tariffs on Chinese electric vehicles, steel and aluminum.
