The American softwood industry is urging the U.S. International Trade Commission to stand firm against Canada, accusing Canadian producers of flooding the market with subsidized lumber. As the Washington-based ITC gets closer to issuing its final determination in December in the trade battle, the U.S. lumber lobby is taking the opportunity to hammer Canada. “The softwood lumber dispute is indeed long-running, but that is because the fundamental problem driving this dispute has not changed: Canadian producers operate in a system that incentivizes production through the government’s provision of low-cost raw materials and other assistance,” the American group said in a recent 376-page filing to the ITC. Barring a trade truce between United States and Canada, the ITC is expected to make its final ruling by Dec. 21. …Canada has steadfastly argued that its industry isn’t subsidized while maintaining Canadian lumber shipments help and don’t hurt the U.S. sector.
