OCTG anti-dumping probe extended to Dec 22, 2025

Summary#

The Canada Border Services Agency has extended the preliminary phase of an anti‑dumping investigation under the Special Import Measures Act into oil country tubular goods (OCTG) from several countries. The preliminary period was lengthened from 90 to 135 days, with a decision scheduled for December 22, 2025.

What it does#

• Extends the preliminary phase of an investigation into alleged injurious dumping of OCTG (pipes used in oil and gas) originating in or exported from Mexico, the Philippines, Türkiye (including goods linked to Borusan Mannesmann Boru Sanayi ve Ticaret A.Ş.), the Republic of Korea (including Hyundai Steel Company) and the United States (including Tenaris S.A.).
• Moves the usual 90‑day preliminary timeline to 135 days because the case involves complex or novel issues, many parties, and difficulty obtaining evidence.
• Sets the date for issuing a preliminary determination or terminating the investigation at December 22, 2025.
• Provides a contact for more information (the SIMA Registry and Disclosure Unit).

Who's affected#

• Importers and distributors in Canada that bring in OCTG (pipe and related assemblies).
• Canadian companies that make or sell OCTG or compete with imported OCTG.
• The named foreign producers/exporters (Borusan Mannesmann Boru Sanayi ve Ticaret A.Ş., Hyundai Steel Company, Tenaris S.A.) and other exporters from the listed countries.
• Industries that buy OCTG, especially the oil and gas sector, which may face price or supply uncertainty.
• If unclear: the notice does not list every company or importer under review, so other firms could also be affected.

Why it matters#

• If the investigation later finds dumping and injury, it can lead to anti‑dumping duties that raise the cost of imported OCTG into Canada.
• The extension means businesses (importers, buyers, and competing domestic producers) will have a longer period of uncertainty about trade rules and prices for these goods.
• A preliminary determination on December 22, 2025 will clarify whether the case proceeds and whether interim measures might follow.
