The U.S. Department of Commerce has finalized its latest review of countervailing duties on Canadian softwood lumber, more than doubling the rate for most producers in a decision that drew criticism from Canadian officials and industry groups.
The department then set the final tariff rate for most Canadian producers—those not individually examined—at 14.63 percent, up from 6.74 percent in the previous review.
The hike comes on top of anti-dumping duties recently raised to 20.56 percent, pushing the combined tariff rate on most Canadian softwood to 35.19 percent. The Commerce Department said U.S. Customs and Border Protection will begin collecting at the new rates immediately.
The move drew praise from the U.S. Lumber Coalition, which said that the measures offset the subsidies that Canadian producers receive from their government.
“Canada has once again demonstrated that it feels entitled to its access to the U.S. market for its massive excess lumber capacity and has gone as far as stating that Canada does not think that the U.S. trade laws should apply to their unfair trade.”
Andrew Miller, Owner of Stimson Lumber Company, accused Canada of escalating its dumping practices “significantly” over the past four years in a bid to maintain its market share in the United States at the expense of American lumber producers, workers, and communities.
The U.S. lumber industry has long said that Canadian producers enjoy an unfair advantage due to government subsidies.
By contrast, the tariff announcement drew swift pushback from Canadian officials and industry leaders, who said the higher duties will worsen housing affordability and strain communities on both sides of the border.
“Two words describe [U.S. President] Donald Trump’s latest move to increase countervailing duties on Canadian softwood lumber: absurd and reckless,” he wrote.
“These duties do nothing but drive up the cost of building materials, stalling home construction in the United States at a time when American families are already struggling with a housing crisis.”
In early August, shortly after the U.S. Commerce Department announced the higher anti-dumping duties against Canadian lumber imports, lumber futures soared to a three-year high, as traders priced in the higher tariffs.
In response to Carney’s move, the U.S. Lumber Coalition called on Trump to “respond forcefully” with new tariffs.
“Canada’s latest $1.2 billion subsidy announcement for its softwood lumber industry will result in job losses in the U.S. forestry sector, plain and simple,” Miller said in a statement.
“We urge President Trump to respond forcefully to this latest Canadian defiance of our trade laws by imposing substantial new tariffs under Section 232. In order to realize continued growth of the U.S. lumber industry, Canada’s flagrant trade law violations must be stopped now.”
The order instructed Commerce Secretary Howard Lutnick to carry out the probe and deliver his findings by the end of 2025.
