Canfor received the highest total rate at 47.65%, with a countervailing duty rate of 12.12% and an antidumping duty rate of 35.53%. West Fraser’s total was the lowest at 26.47%, with a 16.82% countervailing duty rate and a 9.65% antidumping duty rate.

U.S. Customs and Border Protection will collect duties at these levels. The decision follows the department’s April 2025 preliminary findings and represents an increase over previous review results under case numbers A-122-857 and C-122-858. Final rates will become effective once they are published in the U.S. Federal Register, usually within 5-7 days.
Canfor faces highest total rate, West Fraser lowest among reviewed companies.
