Grading lumber products establishes quality control standards among mills manufacturing the same or similar woods. These grades provide a dependable measure for determining the quality of lumber.


The Western Wood Products Association (WWPA) sets official grade rules, conforming to American Lumber Standards, for mills in 12 western states. The WWPA grade stamp, visible on White Pine, Spruce-Pine-Fir and other western species sold at Requarth Lumber, is assurance of its assigned grade.


The Southern Pine Inspection Bureau (SPIB) publishes grading rules under which more than 95% of the production of Southern Pine lumber is sold. To qualify for a SPIB grade-making license, a mill must have well-established credentials in manufacturing, seasoning and grading.
