Provisional Duties on OCTG Imports

Summary#

The Canada Border Services Agency (CBSA) made a preliminary finding on December 22, 2025 that certain oil country tubular goods (OCTG) from several countries may have been dumped into Canada. As a result, provisional duties can be charged while the Canadian International Trade Tribunal (CITT) holds a formal inquiry to decide whether Canadian industry has been harmed.

What it does#

• The CBSA found preliminary dumping for OCTG (casing, tubing and green tubes) from Mexico and the Philippines, and certain shipments produced or exported by:
  • Borusan Mannesmann Boru Sanayi ve Ticaret A.Ş. (originating in Türkiye),
  • Hyundai Steel Company (originating in South Korea),
  • Tenaris S.A. (originating in the United States).
• The goods covered have nominal outside diameters from 2.375 inches to 13.375 inches (60.3 mm to 339.7 mm) and meet API 5CT or equivalent specifications.
• Some items are excluded, including drill pipe, pup joints, unattached couplings, stainless steel tubes with 10.5% or more chromium by weight, and certain seamless products from Tenaris S.A. (see the CBSA for full details).
• Provisional duties became payable on goods released from the CBSA starting December 22, 2025. These duties will not exceed the estimated margin of dumping.
• The Customs Act rules apply to how provisional duties are paid and interest is charged if duties are late.
• The CITT has started an inquiry to decide whether the alleged dumping has caused or threatens to cause injury. The Tribunal must make a final order or finding within 120 days after it gets the CBSA notice.
• Key procedural dates announced by the Tribunal:
  • Deadline to file participation and representation forms: January 6, 2026.
  • Tribunal to publish list of participants: February 10, 2026.
  • Hearing to begin: March 23, 2026.
• The CBSA said a Statement of Reasons will be posted on its website within 15 days of the decision.

Who's affected#

• Importers, distributors and customs brokers who bring OCTG into Canada.
• Canadian companies that buy OCTG for oil and gas drilling or related services.
• The named foreign producers and exporters: Borusan Mannesmann Boru Sanayi ve Ticaret A.Ş., Hyundai Steel Company, and Tenaris S.A.
• Domestic OCTG manufacturers and other Canadian industry players who may have complained or will participate in the Tribunal inquiry.
• If you’re unsure whether a specific product or shipment is covered, the CBSA’s investigation pages list the detailed product descriptions and tariff classifications.

Why it matters#

• Provisional duties can raise the cost or delay the release of OCTG imported into Canada. That can affect drilling projects, equipment costs and supply chains in the oil and gas sector.
• If the Tribunal later finds injury, definitive duties could be imposed, changing long-term import prices and market competition.
• The inquiry is a formal step; this notice is not a final decision on whether dumping caused harm.
