Softwood Lumber Trade Dispute

British Columbia and the forest industry have been engaged for decades with the United States in ongoing Softwood Lumber trade litigation. The 2006 Softwood Lumber Agreement provided stability and predictability until its expiry on October 12, 2015, triggering the latest round in the lumber dispute.

Current state of Softwood Lumber trade with the U.S.

On November 25, 2016, the Committee Overseeing Action for Lumber International Trade Investigations or Negotiations ( “COALITION”) filed a petition with the U.S. Department of Commerce, alleging Canadian lumber is unfairly subsidized and dumped into the U.S. market, launching the “Lumber V” proceedings. B.C. is well prepared to respond to this litigation and will continue to defend B.C.'s interests against these unfounded allegations. B.C. is working alongside the federal government, other Provinces and the forest industry to respond to the ongoing litigation that imposes countervailing duties and anti-dumping duties on Canadian lumber. We also seek recourse through appeals to the US Court of International Trade, the World Trade Organization, and under the Canada/US/Mexico Agreement (formerly NAFTA).

​November 30, 2023: ITC Sunset Review Decision

The U.S. International Trade Commission (ITC) has issued their sunset review decision. The ITC voted in favour of keeping the orders in place, which means that exports of softwood lumber from Canada will continue to be subject to antidumping and countervailing duties. Results of the sunset review will become official once the final determination is published in the U.S. Federal Register, expected late December 2023 or early January 2024.

The sunset review is a requirement under U.S. law for the ITC and U.S. Department of Commerce to review existing antidumping and countervailing duty orders every five years to determine if they are still needed.
