Softwood Lumber Assessment Fee Increase

June 1, 2023

Recently the Softwood Lumber Board has announced the initial assessment rate of 35 cents per thousand board feet is set to increase to 41 cents per thousand board feet beginning April 1st, 2021.

In addition to the fee increase, the Board has also amended the rule to add a conversion factor for square meters to board feet. Currently the order provides for a factor used to convert cubic meters of imported softwood lumber into the equivalent volume of thousands of board feet. This change will enable the Board to assess a more accurate calculation of the assessment.

This is a courtesy notice to inform you that softwood lumber fee will be increasing to 41 cents per thousand board feet on April 1st, 2021.

Please see the Federal Register Notice: 86FR11387, for complete details.
