Steps
Identify the grade needed for the application (e.g., FAS for fine exposed work, No. 1 Common for cabinetry with some allowable imperfections, No. 2 Common for utility/paint-grade use).
Confirm minimum board size and clear-cutting requirements for the specified grade (FAS requires clear cuttings at least 4 in x 5 ft or 3 in x 7 ft).
Inspect incoming shipments against NHLA rule criteria for defects, wane, and cutting yield before accepting delivery.
Reference the current NHLA Rule Book directly, not a secondhand summary, when a grading dispute arises with a supplier.
Document grade discrepancies in writing and pursue resolution with the supplier per standard trade practice before use in production.
Known gotchas
Grading is based on the yield of clear cuttings a board produces, not overall appearance — a board can look rough but still meet grade if the cutting-yield requirement is met.
Species-specific grading nuances exist; don't apply one species' grading examples universally across all hardwoods without checking the current rule book section for that species.
