Lumber tariffs are still pushing up costs
The lumber dispute is easing in tone but not in effect: recent reporting says the U.S. appears to be lowering Canadian softwood lumber tariffs after a preliminary Commerce Department step, yet industry groups call the process dysfunctional and uncertain for buyers and mills ( ). For anyone planning a build or major remodel, the practical takeaway is that price pressure hasn’t disappeared — decisions still face a fragile supply and cost backdrop that could shift as talks or rulings continue (cbc.ca).
The United States looks like it may trim one piece of its Canadian lumber duties, but the bill at the lumberyard is still being shaped by a trade fight that has been running since 2017. A British Columbia report this week said the new preliminary step points to lower softwood lumber tariffs, yet mills and buyers are still stuck waiting for a final ruling expected in August. (cbc.ca) (treefrogcreative.ca) This fight is about Canadian softwood lumber, which is the framing wood used in houses, apartments, roofs, floors, and remodels across the United States. The U.S. government has kept two separate duties on that lumber since early 2017 after trade cases launched in November 2016. (canada.ca) (natural-resources.canada.ca) Those two duties are anti-dumping and countervailing duties. Anti-dumping is the penalty the United States uses when it says a foreign seller charged too little, and countervailing is the penalty it uses when it says a foreign industry was helped by government support. (trade.gov) (ustr.gov) The reason this keeps hitting U.S. construction is simple: Canada is not a side supplier. The National Association of Home Builders says Canada accounts for roughly 85% of all U.S. softwood lumber imports and almost one-quarter of total U.S. supply. (nahb.org) So even when one duty line moves down on paper, builders still have to price jobs against the full stack of costs. The same home builders group said in August 2025 that combined Canadian lumber duties had reached 35%, and by early 2026 it was describing combined duties and tariffs near 45% on some imports. (nahb.org 1) (nahb.org 2) The newest U.S. review does not end the dispute. The Independent Wood Processors Association said the preliminary ruling under Administrative Review 7 still leaves companies waiting for an August final decision, which means mills cannot plan production cleanly and buyers cannot know their real landed cost with confidence. (treefrogcreative.ca) That uncertainty matters as much as the tariff rate itself. A builder signing a fixed-price contract in April can get squeezed if duty rates, freight, or mill output shift before the lumber is actually delivered. (nahb.org) (treefrogcreative.ca) There is also a supply problem underneath the trade fight. The National Association of Home Builders said mills across North America were producing at a loss for much of 2025, and closures and curtailments cut into the supply heading into 2026. (nahb.org) That is why lower demand does not automatically mean lower risk for someone planning a house addition or a full build. Prices in late 2025 were relatively low by recent standards, but the same builders’ group said 2026 could still bring volatility because supply had already been weakened. (nahb.org) The trade case is also still moving through legal channels instead of toward a clean settlement. Canada says it continues to challenge the U.S. measures under the Canada-United States-Mexico Agreement, the World Trade Organization, and U.S. courts, while the U.S. trade office still lists the World Trade Organization softwood case as pending. (natural-resources.canada.ca) (ustr.gov) For anyone pricing a deck, a roof rebuild, or a new house, the practical reality is not “tariffs are over.” It is “one rate may be easing while the system around it is still unstable,” and that is the kind of market where quotes expire fast and contingency lines start to matter.
