CALGARY, Alberta, April 21, 2026 (GLOBE NEWSWIRE) — Today, the Canadian International Trade Tribunal (CITT) ruled that anti-dumping tariffs will be imposed on foreign steel imports sold by Tenaris S.A. and certain exporters from South Korea, Turkey, and the Philippines, following findings that these products were dumped into the Canadian market and caused material injury to the domestic steel industry. The measures will remain in place for five years, in accordance with Canada’s trade remedy laws. CITT’s announcement can be found here.

The case was filed with the CITT and the Canada Border Services Agency (CBSA) by InterPro Pipe + Steel and Welded Tube of Canada Corporation. InterPro is Canada’s only vertically integrated domestic producer of specialized Oil Country Tubular Goods (OCTG) required by the energy sector from steel that is melted and poured in Canada. The ruling is a major victory for the domestic steel industry and aligns with Prime Minister Mark Carney’s Buy Canadian initiative, which aims to bolster Canadian manufacturing and create a level playing field for Canadian companies and workers.

Tenaris S.A., headquartered in Luxembourg and operating facilities across Canada, along with exporters from South Korea, Turkey, and the Philippines, were selling dumped foreign steel into Western Canada, according to a determination of the CBSA on March 23, 2026. The CITT followed that determination today with an anti-dumping ruling and imposition of tariffs that will ensure a minimum fair-trade price, and Tenaris S.A. and other exporters of dumped steel products can no longer benefit from using cheap steel, including from countries that allow abusive labour practices and low environmental standards.

“This decision sends a clear message: Canada will not allow its workers and industries to be undercut by unfair trade,” said Doug Matthews, Director, InterPro & CEO, Orion Steel. “The evidence showed that dumped steel, often produced under weaker labour protections and lower environmental standards, was being used to displace high-quality Canadian steel made by skilled union workers. That is not a level playing field, and today’s ruling helps correct it and aligns directly with the Prime Minister’s ‘Buy Canadian’ agenda. If we are serious about strengthening domestic manufacturing, supporting good-paying union jobs, and securing our energy supply chain, then enforcement of our trade laws is essential. Today’s decision proves that Canada is prepared to act.”
