The U.S. Court of International Trade ruled on July 21, 2026, to uphold the U.S. Department of Commerce’s fourth remand results regarding countervailing duties on softwood lumber products imported from Canada. This decision impacts companies involved in the lumber trade between the U.S. and Canada, particularly those affected by subsidy rates and trade regulations.

The case, titled Committee Overseeing Action for Lumber International Trade Investigations or Negotiations v. United States, Consol. Court No. 19-00122, centers on the calculation of subsidy rates for certain Canadian lumber products. The ruling is significant as it shapes the future of trade practices and duties applied to imported lumber, which has been a contentious issue in U.S.-Canada trade relations.

The parties involved in this case include the Committee Overseeing Action for Lumber International Trade Investigations or Negotiations (the Coalition), which represents U.S. lumber producers, and Les Produits Forestiers D&G Ltée and Les Produits Forestiers Portbec Ltée (D&G/Portbec), which are Canadian lumber producers. The Coalition argues that D&G/Portbec received unfair subsidies that distort competition in the U.S. lumber market. The dispute reached the Court of International Trade after multiple reviews and remands by the Department of Commerce regarding the subsidy calculations.

The case stems from a countervailing duty order issued by the Department of Commerce, which found that certain softwood lumber products from Canada were subsidized by the Canadian government. The Coalition challenged the subsidy rates determined by Commerce, leading to a series of remands and recalculations of the subsidy rates. The court had previously ruled that Commerce needed to reconsider its calculations and methodologies.

In its latest ruling, the court sustained the Department of Commerce's fourth remand results, which involved a recalculation of the subsidy rate for D&G/Portbec. The court noted that Commerce had appropriately reopened the record to allow D&G/Portbec to submit additional information regarding their purchases of lumber. The judge, Mark A. Barnett, stated, "Commerce concluded that the Respondents provided information that was 'sufficiently representative of Portbec’s purchases' of lumber imported into the United States." This led to a revised subsidy rate of 1.05 percent for D&G/Portbec, down from a previous rate of 1.75 percent.

The court's decision emphasized that D&G/Portbec's overall subsidy rate remains above the de minimis threshold, meaning they are still subject to the countervailing duty order. The ruling also addressed D&G/Portbec's arguments regarding upstream subsidies and the treatment of lumber as an input product, ultimately siding with Commerce's interpretation of the regulations.

This ruling has significant implications for the lumber industry, particularly for U.S. producers who argue that subsidized Canadian lumber creates an unfair competitive advantage. The decision reinforces the current regulatory framework governing countervailing duties and the treatment of subsidies in international trade.

Looking ahead, the ruling may influence future cases involving trade practices and subsidy calculations in the lumber industry. D&G/Portbec may seek to appeal the court's decision, but details on any potential appeal were not available in the court filing. The ongoing scrutiny of trade practices between the U.S. and Canada suggests that this issue will remain a focal point in international trade discussions.
