Grade "B": Selected one-piece face generally light and even in color. Occasional small pin knots and some brown streaks may be allowed. Intended for natural finish. No patches allowed. The majority of Grade B veneers are the equivalent of American one-piece select white birch faces.

Grade "BB": One-piece face generally light and even in color. Occasional sound tight knots are permitted  but open knots and defects in BB have been cut out and replaced with small ovular or round veneer patches before gluing. The veneer selected for the patches is of the same general color as the basic face veneer. Generally there are very few patches per face and many users purchase this grade for cut up for natural finish.

Grade "CP": One-piece face and very close to Grade BB in quality. Occasional hairline splits are allowed in Grade CP. The ovular or round patches may or may not be matched for color with the base face veneer. There  may be more patches per face than in Grade BB.

Grade "C": One-piece utility grade veneer available both sanded and unsanded . Open defects and open splits are allowed. Recommended for container, crating, dust panels and usages where construction and strength are important factors and appearance is not important.
