Dumping probe: oil country tubular goods

Summary#

The Canada Border Services Agency (CBSA) made a preliminary finding of dumping of certain oil country tubular goods on December 22, 2025. As a result, provisional duties can be charged while the Canadian International Trade Tribunal (CITT) holds a full inquiry to decide if Canadian industry has been injured.

What it does#

• The CBSA found preliminary evidence of dumping under the Special Import Measures Act for oil country tubular goods (casing, tubing and green tubes) from several countries and specific producers, including Borusan Mannesmann Boru Sanayi ve Ticaret A.Ş., Hyundai Steel Company, and Tenaris S.A..
• Provisional duties are payable on affected goods released from CBSA custody starting December 22, 2025, and continue until the investigation ends, the CITT issues an order, or an undertaking is accepted.
• The provisional duty charged will not be greater than the estimated margin of dumping. The Customs Act rules apply for accounting and interest if duties are not paid on time.
• The CITT will conduct a full inquiry to determine whether dumping has caused, is threatening to cause, or has retarded injury to Canadian producers. The tribunal must make an order or finding within 120 days after receiving the CBSA’s notice.
• The CBSA will publish a Statement of Reasons within 15 days of the decision and lists of product definitions and possible tariff classifications on its website.
• The CITT has set procedural dates for the inquiry: participant and counsel forms are due by January 6, 2026, a list of participants will be issued on February 10, 2026, and a hearing will begin on March 23, 2026.
• The investigation covers goods with a nominal outside diameter from 2.375 inches to 13.375 inches (60.3 mm to 339.7 mm), meeting API specification 5CT or equivalent. Certain items are excluded (for example: drill pipe, pup joints, unattached couplings, some stainless-steel tubes, and specific Tenaris seamless products).

Who's affected#

• Importers and distributors of oil country tubular goods into Canada.
• Companies that produced or exported the specific goods named, including Borusan Mannesmann Boru Sanayi ve Ticaret A.Ş., Hyundai Steel Company, and Tenaris S.A..
• Canadian manufacturers of similar tubing and casing who are claiming injury.
• Buyers in the oil and gas sector (operators, service companies) who may face higher import costs or supply changes.
• Customs brokers and logistics firms that handle release and duty payments.
• If unclear: the exact financial impact and which importers will pay duties depends on the final margins and the CITT’s findings.

Why it matters#

• Importers may suddenly face extra costs while the case runs. Those costs can flow to oil-and-gas customers and contractors.
• The full inquiry could lead to final anti-dumping duties if the CITT finds injury. That can protect domestic producers but also raise prices for users of the goods.
• The timeline is relatively short: provisional duties started December 22, 2025, and the tribunal aims to decide within 120 days, so affected parties should act quickly if they want to participate.
