OCTG dumping investigation extended

Summary#

The Canada Border Services Agency (CBSA) announced an extension of the preliminary phase of an investigation under the Special Import Measures Act (SIMA) into the alleged injurious dumping of oil country tubular goods (OCTG). The preliminary stage was extended from 90 days to 135 days, and the CBSA says it will make a preliminary decision or end the investigation on December 22, 2025 (decision announced October 30, 2025).

What it does#

• Extends the preliminary investigation period under SIMA from 90 days to 135 days.
• Keeps the investigation focused on OCTG (pipe used in oil and gas wells) allegedly dumped into Canada from:
  • United Mexican States,
  • Republic of the Philippines,
  • Republic of Türkiye — specifically goods exported or produced by, or on behalf of, Borusan Mannesmann Boru Sanayi ve Ticaret A.Ş.,
  • Republic of Korea — specifically exported or produced by, or on behalf of, Hyundai Steel Company,
  • United States of America — specifically exported or produced by, or on behalf of, Tenaris S.A.
• Sets the date for a preliminary determination or termination of the investigation: December 22, 2025.
• The CBSA says the extension is needed because of the complexity and novelty of issues, the number of people involved, and difficulty obtaining satisfactory evidence.

Who's affected#

• Importers, distributors and buyers of oil country tubular goods in Canada.
• Canadian oil and gas companies and contractors that buy OCTG.
• Domestic manufacturers of similar pipe and related products who may have filed or supported the complaint.
• Exporters and producers named or covered by the investigation, including Borusan Mannesmann Boru Sanayi ve Ticaret A.Ş., Hyundai Steel Company, and Tenaris S.A., and exporters from the listed countries.
• Customs brokers and supply-chain businesses that handle OCTG shipments.
• If it’s unclear who exactly is affected in a specific case, affected businesses and importers should check the CBSA notice or contact the agency.

Why it matters#

• The extension delays a preliminary outcome. That keeps uncertainty in place for buyers and sellers of OCTG.
• If the investigation later finds dumping that injures Canadian industry, it could lead to duties or other trade measures. That could raise costs or change supply arrangements for the oil and gas sector.
• The longer timeline reflects a complex case with multiple countries and companies involved, so businesses should watch for the December 22, 2025 decision and consider contingency plans.
