The U.S. has slapped final anti-dumping and countervailing duties on Canadian lumber, the latest step in another lengthy legal battle over softwood. …Commerce Secretary Wilbur Ross said the U.S. is confident the World Trade Organization, which may end up having to rule on the dispute, will eventually side with the U.S. “The Trump administration will continue to stand up against unfair trade practices that harm American workers and businesses,” Ross said in a statement. “Even our closest allies must follow the rules.” …“It’s pretty much a rubber stamp on what we were expecting,” said Kevin Mason, managing director Vancouver-based ERA Forest Products Research. It means Canadian producers will resume paying the countervailing duty, the preliminary version of which had expired, but have the benefit of a relatively predictable environment for the year ahead, he said.
