Pacific Lumber Inspection Bureau - PLIB

PLIB staff attended the Portland Wholesale Lumber Association sawmill tour last Thursday and had a great time touring Superior Wood Treating (Manke Lumber Co Inc - Sumner) and Manke Lumber Company Inc to learn all about how the manufacturing side of our industry works. It was a fantastic opportunity to see behind the scenes and get a picture of where it all begins with lumber. We are very grateful to PWLA and Manke Lumber for the opportunity!!

The recent meeting of the PLIB Grade and Technical Committee highlighted the important role that member engagement plays in the continuous development of lumber grading standards.
The Committee provides a forum for PLIB members to actively contribute to the rules and standards that underpin the North American lumber industry. Many of the recent changes to the National Grading Rules originated as proposals from PLIB members and were developed through the collaborative work of this committee.

At the May meeting, discussions focused on several grading clarifications, including knot size definitions for knots occurring in finger-jointed lumber. These types of technical reviews help ensure that grading requirements remain clear, consistent, and practical for producers, customers, and inspectors alike.

Standards and grading rules are living documents that must evolve alongside industry practices, manufacturing technologies, and market needs. PLIB is grateful for the dedication and expertise of the committee members who generously contribute their time and knowledge to this process.

Thank you to all participants for helping strengthen the standards that support confidence, consistency, and quality throughout the lumber industry.
