CITT Hits Tenaris S.A., Offshore Exporters With Steel Pipe Tariffs
04/23/2026 - Interpro Pipe + Steel announced the Canadian International Trade Tribunal (CITT) ruled antidumping tariffs will be imposed on foreign steel imports sold by Tenaris S.A. and various exporters from South Korea, Türkiye and the Philippines for 5 years.
“The evidence showed that dumped steel, often produced under weaker labor protections and lower environmental standards, was being used to displace high-quality Canadian steel made by skilled union workers,” said Doug Matthews, director of Interpro and chief executive officer of Orion Steel Companies.
Interpro Pipe + Steel and Welded Tube of Canada Corp. filed the case with the CITT and the Canada Border Services Agency (CBSA). The companies said Tenaris S.A. was selling dumped foreign steel into Western Canada from its exporters in South Korea, Türkiye and the Philippines, causing issues within the domestic steel industry.
The CBSA released its findings on 23 March: “Based on the available evidence, the CBSA is satisfied that oil country tubular goods (OCTG) originating in or exported from the subject countries and exporters/producers has been dumped.”
The CITT released its findings on Tuesday: “The Tribunal today found that the dumping of oil country tubular goods, originating in or exported from Mexico, the Philippines, Türkiye, South Korea and the United States, has caused injury to the domestic industry.”
Going forward, the CBSA will collect the tariffs when the steel enters Canada while the imports will pay the costs to ensure foreign steel doesn’t flood the market, Interpro said.
“That is not a level playing field, and [the CITT’s] ruling helps correct it and aligns directly with the Prime Minister’s ‘Buy Canadian’ agenda,” continued Matthews.
The CITT said it will issue additional information on 6 May.
