The softwood lumber trade dispute between the US and Canada, which has led to ever-higher US import duties on Canadian lumber, has lasted for decades. …Canadian lumber has the backing NAHB, which sees lumber tariffs as exacerbating high costs for builders and worsening the US housing affordability crisis. There is currently a “Wall of Wood” in the US, after Canadian producers increased shipments to the US in anticipation of the hike to existing ADD and CVD duties in August. Expectations that a large increase in duties would force the closure of Canadian sawmills, lead to shortages, and a boost in lumber prices, overlooked the current weak US demand for lumber, according to Matt Layman. …As US homebuilders now face additional tariff-driven costs, including a 50% tariff on cabinets and vanities, it’s hard to see the lumber demand situation improving, even if more Canadian suppliers have to curtail production or close sawmills.
