China will impose a 73.5% preliminary tariff on imports of Canadian pea starch starting July 1, the Ministry of Commerce announced Tuesday.

The measure is part of temporary anti-dumping actions following an investigation that concluded Canadian exports were being sold at unfairly low prices, causing material injury to domestic producers.

The tariff comes after more than 10 months of scrutiny by Chinese authorities.

While the levy is preliminary, it signals a hardening stance on agricultural trade with Canada and could disrupt supply chains for processors relying on Canadian inputs.

The move adds to a broader pattern of Beijing using trade remedies to shield domestic industries from foreign competition.

This development occurs as China continues to tighten its trade posture globally.
