4412.31.26.20 - With a face ply of walnut (Juglans spp.)

This HTS category specifically classifies plywood and similar laminated wood products where the primary outer layer, or face ply, is composed of walnut (Juglans spp.). These products must meet the general criteria of being made solely from sheets of wood (excluding bamboo), with each ply not exceeding 6 millimeters in thickness. Furthermore, they are not surface covered, or if they are, the covering is clear or transparent, allowing the grain, texture, and markings of the walnut face ply to be visible.

This category is distinguished from its sibling category, 4412.31.26.10, by the specific species of wood used for the face ply. While both fall under "With a face ply of Spanish cedar (Cedrela spp.) or walnut (Juglans spp)", this particular subcategory exclusively covers products where the visible outer layer is walnut, whereas the sibling category covers those with Spanish cedar.

As a leaf node in the HTS classification system, this category represents the most specific level of detail for this type of product. Therefore, there are no further subcategories to introduce. Classification under this code hinges entirely on the presence of a walnut face ply meeting the described characteristics, differentiating it from other forms of plywood and laminated wood.
