4412.31.06 - With a face ply of birch (Betula spp.)

This HTS classification pertains to plywood and similar laminated wood panels where the outer layer, or face ply, is specifically made of birch wood (Betula spp.). These products are characterized by consisting solely of wooden sheets, excluding bamboo, with each individual ply not exceeding 6 millimeters in thickness. They must also feature at least one outer ply of tropical wood, and their surface must be either uncovered or covered with a transparent material that does not hide the natural grain, texture, or markings of the birch face ply.

This category is distinguished from its sibling category, 4412.31.26, which specifically covers plywood with a face ply of Spanish cedar (Cedrela spp.) or walnut (Juglans spp). The key differentiator here is the species of wood used for the face ply; this subcategory is exclusively for birch.

The subcategories for 4412.31.06 further refine the classification based on the physical dimensions of the panels. Specifically, there is a category for panels not exceeding 3.6 mm in thickness, 1.2 m in width, and 2.2 m in length. The "Other" subcategory then encompasses all birch-faced plywood that does not meet these specific dimensional criteria, ensuring comprehensive coverage of birch-faced plywood within this classification level.
