Do you believe recent changes to lumber import assessments will increase costs for your future home projects?
The USDA will implement a revised calculation method for softwood lumber import assessments beginning October 22, 2026. This change aims to reconcile measurement discrepancies between European net-size reporting and standard nominal dimensions.
Why it matters
Current regulations lacked the specificity to account for volume differences in imported European lumber. This update ensures uniform assessment rates and will expand the Softwood Lumber Board to better represent domestic production regions.
The new rule sets an assessment of $0.62 per thousand net board feet to align with the existing $0.41 nominal rate. These changes are expected to increase the Softwood Lumber Board's annual budget by over $367 thousand.
The players
U.S. Department of Agriculture
The federal executive department responsible for developing and executing laws related to farming, forestry, and food.
Softwood Lumber Board
An industry-funded organization that promotes the benefits of softwood lumber and oversees research and development projects.
The details
The USDA will require all manufacturers and importers to use nominal volume for assessment thresholds, maintaining an exemption for the first 15 million board feet annually. Additionally, the Softwood Lumber Board will grow from 15 to 16 members to include a dedicated seat for the U.S. South, where production averaged 22.1 billion board feet from 2022 to 2024.
Timeline
The Softwood Lumber Board first identified the reporting discrepancy in 2021.
U.S. regions recorded production data from 2022 through 2024.
The new assessment rule is scheduled to take effect on October 22, 2026.
Market Landscape
The adjustment to the Softwood Lumber Board assessment program reflects a broader effort to standardize international trade reporting requirements. By aligning European net-size metrics with U.S. nominal standards, the USDA is standardizing the competitive landscape for domestic and international lumber suppliers.
The standardized assessment calculation aims to ensure a level playing field among lumber importers, potentially stabilizing pricing structures for construction materials. While the change primarily affects institutional reporting, it ensures the Softwood Lumber Board receives the appropriate funding to support ongoing industry research and promotion.
The takeaway
This adjustment ensures that assessment fees remain consistent regardless of whether lumber is measured by net or nominal dimensions. Industry participants should prepare for the October 2026 effective date to ensure compliance with the updated reporting framework.
