U.S. officials warned Canada in February that its tariffs on Canadian softwood lumber would increase, but a final decision on Tuesday that nearly doubled them was a body blow to an already challenged industry. The U.S. Department of Commerce announced its decision, which will start being applied to American imports of Canadian lumber almost immediately, to increase the total tariffs to an average rate of 14.54% from 8.05% a year ago. “It’s not welcome at all, particularly for B.C. (which is) faced with a number of challenges,” said Kurt Niquidet, of the B.C. Lumber Trade Council. “We’re a high-cost producer, so this just adds to the cost of shipping to our major market.” …“You might see curtailments as a result, all depending on how markets, more broadly, move over the next little while,” Niquidet said. …The new tariffs add US$58 to the price paid by U.S. buyers compared with $32 under the previous rate.
