The Canadian International Trade Tribunal (CITT) ordered five-year anti-dumping (AD) duties on Oil Country Tubular Goods (OCTG) imports to protect domestic manufacturers. This ruling addresses goods priced below fair market value that caused injury to the local industry.

The measures apply to all shipments originating from Mexico and the Philippines. Duties also cover products from Turkey’s Borusan Mannesmann Boru Sanayi ve Ticaret A.Ş., South Korea’s Hyundai Steel Company, and United States-based Tenaris S.A.

The Canada Border Services Agency (CBSA) determined these entities engaged in dumping practices on March 23, 2026. InterPro Pipe + Steel and Welded Tube of Canada Corporation initiated the case.

By enforcing these tariffs, the government secures national energy supply chains and maintains a level playing field for Canadian producers. This decision preserves fair market prices and prevents cheap foreign steel from undermining local manufacturing capabilities.
