An explanation of the American hardwood lumber grades by NHLA
This video workshop provides a simplified but informative explanation of the grading rules for American hardwood lumber. Presented by Dana Spessert, Chief Inspector of the NHLA, the rules were established over 125 years ago by the, then newly formed, National Lumber Association (NHLA). Today the NHLA has over 650 members worldwide and the NHLA rules are still the national standard for the U.S. hardwood industry and form the basis for grading of export lumber.
More information on grading and species can be found in AHEC’s Guide to sustainable American hardwoods.
