Canada Imposes Anti-Dumping and Countervailing Duties on Chinese Cast Iron Soil Pipe

CITT Finds Injury in Chinese Pipe Imports

Ottawa, Ontario – The Canadian International Trade Tribunal (CITT) announced on February 6, 2026, its finding that the dumping and subsidizing of certain cast iron soil pipe originating in or exported from China have caused injury to the Canadian domestic industry. This decision paves the way for the Canada Border Services Agency (CBSA) to collect anti-dumping and countervailing duties on these imports.

Investigation Initiated by Domestic Complaint

The CITT's finding follows a comprehensive investigation initiated on July 11, 2025, by the CBSA, based on a complaint filed by Canada Pipe Company ULC, operating as Bibby-Ste-Croix, a Quebec-based firm. The complaint alleged that unfair pricing practices from Chinese exporters were harming the Canadian market. The subject goods include finished or unfinished cast iron soil pipe, encompassing both hubless and hub and spigot designs, with a nominal outside diameter ranging from 1.5 inches to 18 inches.

Dumping and Subsidizing Confirmed

Prior to the CITT's final injury determination, the CBSA had already made its final determinations of dumping and subsidizing on January 7, 2026. The CBSA found significant margins of dumping, ranging from 155.5% to 444.2%, and a subsidy amount of 28.5%. These findings indicated that Chinese cast iron soil pipe was being sold in Canada at unfairly low prices and benefiting from government subsidies. Provisional duties had been in effect since October 9, 2025.

Impact on Canadian Industry

Bibby-Ste-Croix, the sole known producer of cast iron soil pipe in Canada, detailed various forms of injury caused by the dumped and subsidized imports. These included:

• Lost market share
• Price undercutting, suppression, and depression
• Adverse impacts on production, capacity utilization, and inventory levels
• Negative effects on financial performance and profitability
• Adverse impacts on employment, wages, and operations
• Jeopardy to investment and ability to raise capital

The CITT's final injury finding confirms that these unfair trade practices have indeed caused material injury to the domestic industry.

Next Steps

With the CITT's injury finding, the Canada Border Services Agency will now proceed with the collection of definitive anti-dumping and countervailing duties. The CITT is expected to issue the detailed reasons for its findings on February 23, 2026. These duties will be applied for up to five years to counteract the injurious effects of the dumped and subsidized imports.
