The United States Court of International Trade has ruled in favor of the U.S. Department of Commerce regarding its pricing analysis of Canadian softwood lumber imports. This decision, issued on July 27, 2026, affects Canadian lumber producers and U.S. importers, as it sustains the Department's revised approach to calculating antidumping duties. The ruling is significant as it sets a precedent for how price differences in international trade are assessed.
The case, Government of Canada v. United States, Consol. Court No. 23-00187, involved multiple Canadian parties, including provincial governments and lumber companies, challenging the Department of Commerce's methodology for determining whether Canadian softwood lumber was being sold at less than fair value in the U.S. market. The outcome of this case is crucial for the lumber industry, which has faced ongoing trade disputes between Canada and the United States.
The dispute began when the U.S. Department of Commerce initiated an administrative review of antidumping duties on certain softwood lumber products from Canada. In its final determination, Commerce assigned various dumping margins to different Canadian companies, including 5.25% for Canfor Corporation and 6.96% for West Fraser Mills Ltd. The Canadian parties contested this determination, leading to a series of appeals and remands, including a significant ruling from the U.S. Court of Appeals for the Federal Circuit in 2025.
In the recent ruling, Judge Jennifer Choe-Groves upheld the Department of Commerce's Remand Redetermination, which revised its differential pricing analysis following the appellate court's directive. The court stated, "Commerce's differential pricing analysis used in these final results of redetermination examines whether there exists a pattern of prices for comparable merchandise that differ significantly among purchasers, regions, or time periods." This ruling confirms that the Department's new methodology, which replaced the previously used Cohen’s d test with a three-step analysis, is valid and legally sound.
The court's decision means that the Department of Commerce can continue using its updated pricing analysis, which includes a new "price difference test" to determine if significant price differences exist among different purchasers or regions. If such differences are found, the Department can apply an alternative method for calculating dumping margins, which may lead to higher duties on imported lumber.
This ruling is expected to have a lasting impact on the softwood lumber industry, as it reinforces the authority of the Department of Commerce to set and adjust antidumping duties based on its pricing methodologies. The decision may also influence future trade relations between Canada and the United States, particularly in how both countries approach pricing and trade disputes in the lumber sector.
Moving forward, the Canadian parties may consider appealing this ruling to a higher court, although details about any potential appeal were not available in the court filing. The outcome of this case could set important precedents for future cases involving international trade and pricing methodologies.
