4412.59.90.00 - Other

This category encompasses "other" plywood not specifically described in preceding HTS subheadings. It is crucial to understand that within the broader context of plywood, this classification serves as a residual for products that do not fit more specific descriptions. The key defining characteristic of items falling under 4412.59.90.00 is their categorization as plywood based on construction (multiple layers of wood veneers glued together with adhesives) but lacking the specific outer ply material or surface treatment that would place them in more narrowly defined subcategories.

To distinguish this category from its siblings, consider the preceding classifications. If plywood has outer plies of coniferous wood, it would be classified elsewhere. Similarly, if the plywood's surface is covered with materials that obscure the grain, texture, or markings of the face ply, it would also be directed to a different classification. Therefore, this "other" category is for plywood that does not meet those precise specifications, often implying outer plies of non-coniferous wood or other distinguishing features not covered by the more specific headings.

As this is a leaf node in the HTS structure, there are no further subcategories to introduce. Classification within 4412.59.90.00 is therefore dependent on a comprehensive review of the plywood's construction and surface treatment, ensuring it does not qualify for any more specific HTS code within Chapter 44, particularly under the broader headings for plywood and similar laminated wood.
