The above-listed tariff classifications cover both subject and non-subject goods and are for convenience of reference only. Refer to the product definition, for authoritative details regarding the subject goods.

The Canadian International Trade Tribunal (CITT) will continue its inquiry into the question of injury to the Canadian industry and will issue its decision by April 21, 2026. Provisional duties will continue to be imposed on the subject goods from the subject countries and exporters/producers until the CITT renders its decision.

Additional information about this investigation is contained in a Statement of Reasons, which will be available within 15 days.

For assistance in properly completing accounting documents and the payment of provisional duties, please consult the Guide for self-assessing SIMA duties.

Margins of dumping

Country of origin/export	Exporter	Margin of dumping (% of export price)
Mexico	Tubos de Acero de Mexico S.A.	30.7%
Philippines	HLD Clark Steel Pipe Co. Ltd.	16.7%
	All other exporters	57.5%
South Korea	Hyundai Steel Pipe Co., Ltd.	13.6%
Türkiye	Borusan Birleşik Boru Fabrikalari Sanayi Ve Ticaret A.Ş.	11.0%
United States	Maverick Tube Corporation	13.9%
Note The margins of dumping reported in the table above are the margins determined by the Canada Border Services Agency (CBSA) for purposes of the final determination of dumping. These margins do not reflect the anti-dumping duty to be levied on future importations of dumped goods. In the event of an injury finding by the Canadian International Trade Tribunal, normal values have been provided to the exporters which provided sufficient information for future shipments to Canada and these normal values would come into effect the day after the injury finding. Information regarding normal values of the subject goods should be obtained from the exporter. Imports of subject goods from exporters/producers that did not provide sufficient information to the CBSA during the dumping investigation and who are not listed in the table above will be subject to the All-Other Exporters anti-dumping duty rate pursuant to a ministerial specification. Specifically, normal values for these exporters will be determined by advancing the export price by 167.0% for Mexico, 57.5% for the Philippines, 57.4% for South Korea, 67.9% for Türkiye, and 33.5% for the United States of America, of the export price, pursuant to Ministerial Specification. The export price is generally the lesser of the exporter’s selling price or the importer’s purchase price as provided for in section 24 of SIMA. Normally, normal values will not be applied retroactively. However, normal values may be applied retroactively in cases where the exporter does not adjust export prices to account for increases in domestic prices and/or costs that affect values for SIMA purposes. Therefore, where substantial changes occur in prices, market conditions, costs associated with production and sales of the goods, the onus is on the concerned parties to increase the export price accordingly to ensure that any sale made to Canada is not only above the normal value but at or above selling prices and full costs and profit of the goods in the exporter’s domestic market.
