4412.33.26 - With a face ply of walnut (Juglans spp.)

This HTS classification covers plywood and similar laminated wood products where at least one of the outer plies is made from specific types of nonconiferous wood, and specifically features a face ply of walnut (Juglans spp.). The key defining characteristic here is the prominent use of walnut as the visible surface layer. These products are not surface covered, or if they are, the covering is clear or transparent and does not hide the natural grain, texture, or markings of the walnut face ply.

This category is distinct from its sibling, HTS 4412.33.06, which covers similar plywood but specifically with a face ply of birch (Betula spp.). Therefore, the primary differentiator lies in the species of wood used for the outermost visible layer. If the face ply is walnut, it falls under this heading; if it's birch, it would be classified under the sibling.

Within this classification, further subdivisions exist to refine the nature of the walnut-faced plywood. HTS 4412.33.26.25 specifically designates wood flooring made from this type of plywood. The remaining products that do not meet the criteria for wood flooring are captured under the broader "Other" subcategory (HTS 4412.33.26.30). This structure allows for precise classification based on both the face material and the intended end-use of the laminated wood product.
