OCTG anti-dumping investigation

Summary#

The Canada Border Services Agency (CBSA) opened an anti‑dumping investigation on August 11, 2025 into alleged injurious dumping of oil country tubular goods (OCTG). The probe covers goods from several countries and specific named exporters; a short explanation of the decision will be published within 15 days.

What it does#

• Starts an investigation under the Special Import Measures Act (SIMA) into claims that OCTG sold into Canada from certain places were dumped and harmed the domestic industry.
• Lists the countries and some specific producers under review:
  • United Mexican States
  • Republic of the Philippines
  • Republic of Türkiye — products exported or produced by or for Borusan Mannesmann Boru Sanayi ve Ticaret A.Ş.
  • Republic of Korea — products exported or produced by or for Hyundai Steel Company
  • United States of America — products exported or produced by or for Tenaris S.A.
• Notes that the full product definition and tariff numbers are on the CBSA’s Dumping and subsidy investigations webpage.
• States that a Statement of Reasons explaining the decision will be issued within 15 days of the decision date.

Who's affected#

• Canadian companies that make or sell OCTG (the oil and gas industry uses these pipes).
• Importers, distributors and buyers of OCTG in Canada.
• Exporters and producers in the named countries, including Borusan Mannesmann Boru Sanayi ve Ticaret A.Ş., Hyundai Steel Company, and Tenaris S.A.
• It may also matter to service companies and customers in sectors that use these pipes (oilfield services, drilling companies).

Why it matters#

• This is the first step in a process that can lead to duties or other trade measures if dumping and injury are found. That could raise the cost of imported OCTG or shift supply sources.
• Domestic OCTG producers may gain protection if injury is confirmed. Importers and end users could face higher prices or tighter supply while the case proceeds.
• The CBSA’s public product definition and the forthcoming Statement of Reasons will clarify exactly which items and tariff codes are covered, which matters to businesses deciding whether they are affected.
