Another chapter in the ongoing softwood lumber dispute between the United States and Canada was opened on September 1. Canada’s Trade Minister Mary Ng announced that Canada was launching a Chapter 10 United States-Mexico-Canada Agreement (USMCA) challenge to the latest countervailing duties (CVD) in place on importations of softwood lumber into the U.S. Additionally, a suit is being filed by Canada in the U.S. Court of International Trade to challenge the antidumping duties (ADD) on softwood lumber from Canada also now in effect.

The dispute goes back to 1981 when the U.S. lumber industry first requested the Department of Commerce to investigate Canadian stumpage programs and impose countervaling duties. The issue is rooted in the fact that most Canadian land where softwood lumber is harvested from is owned by provincial governments, and the fees charged to harvest timber on the land, or the stumpage rates, are set by government regulation. In the United States, most softwood timber land is privately owned and the stumpage rates are determined by market forces. U.S. lumber companies have long claimed that the stumpage rates charged to harvesters by the provinces in Canada are well below market rates and are, therefore, countervailable subsidies. An agreement to suspend the application of any ADD or CVD that had been in effect expired in 2015, and the battle has raged on ever since. The World Trade Organization (WTO) ruled in favor of Canada in 2020 and stated that the United States CVD measures were not in conformity with its WTO obligations. However, the U.S. has ignored that determination for the most part. Talks between the leaders of Canada and the U.S. in Ottawa earlier this year did not break the impasse.
