New Western Lumber Grading Rules Is Available

The new edition of Western Lumber Grading Rules is available from the WWPA Online Store. The book includes new rules changes and added material, the most significant being the addition of the Grading Interpretations of the National Grading Rule for Dimension Lumber. It provides additional clarification and guidance to lumber graders and inspectors in the application of the National Grading Rule.

The NGR booklet was traditionally offered from WWPA by request only. Now this valuable information will be accessible with all purchases of the Western Lumber Grading Rules. The 2025 edition is the most comprehensive and up-to-date version yet. The book is available in perfect bound and coil bound binding. Visit wwpastore.org to order your copy.
