OCTG anti-dumping investigation extended

Summary#

On October 30, 2025, the Canada Border Services Agency (CBSA) extended the preliminary phase of an anti‑dumping investigation under the Special Import Measures Act (SIMA) into oil country tubular goods (OCTG) from several countries and specific producers. The preliminary period will be lengthened from 90 days to 135 days, and a decision is scheduled for December 22, 2025. (Published in the Canada Gazette on November 8, 2025.)

What it does#

• Extends the preliminary investigation period for alleged injurious dumping of OCTG to 135 days (normally 90 days).
• Covers OCTG originating in or exported from:
  • the United Mexican States;
  • the Republic of the Philippines;
  • the Republic of Türkiye, specifically exported or produced by, or on behalf of, Borusan Mannesmann Boru Sanayi ve Ticaret A.Ş.;
  • the Republic of Korea, specifically exported or produced by, or on behalf of, Hyundai Steel Company;
  • the United States of America, specifically exported or produced by, or on behalf of, Tenaris S.A.
• Explains the extension is because of the complexity and novelty of the issues, the number of parties involved, and the difficulty of obtaining satisfactory evidence.
• Sets the decision date: the CBSA will either issue a preliminary determination or terminate the investigation on December 22, 2025.
• For more information, the notice points to the SIMA Registry (email: simaregistry-depotlmsi@cbsa-asfc.gc.ca).

Who's affected#

• The named foreign producers and exporters: Borusan Mannesmann Boru Sanayi ve Ticaret A.Ş., Hyundai Steel Company, and Tenaris S.A.
• Businesses exporting OCTG from the United Mexican States, the Republic of the Philippines, the Republic of Türkiye, the Republic of Korea, and the United States of America to Canada.
• Canadian companies that import or use OCTG (for example, firms in the oil and gas, construction, or transportation sectors) could see effects if duties or measures follow from the investigation.
• The precise list of affected importers and downstream users is not given in the notice.

Why it matters#

• An extended investigation delays clarity about whether anti‑dumping duties or measures will be applied. That uncertainty can affect pricing, contracts, and procurement decisions for businesses that buy OCTG.
• If the CBSA issues a preliminary finding of injurious dumping on December 22, 2025, that could lead to provisional duties while the case continues — potentially raising costs for importers and their customers.
• If the investigation is terminated, importers and users would avoid additional measures but may have faced months of uncertainty.
