4412.59 - Other, with both outer plies of coniferous wood:

This HTS category, 4412.59, specifically addresses plywood and similar laminated wood where both of the outer plies are constructed from coniferous wood. This designation is critical for distinguishing it within the broader classification of plywood and laminated wood products.

It differentiates from its siblings by its exclusive reliance on coniferous wood for the outer layers. For instance, 4412.51 covers products with at least one outer ply of tropical wood, and 4412.52 pertains to those with at least one outer ply of nonconiferous wood. The defining characteristic here is the absence of tropical or other nonconiferous woods on the exterior surfaces.

Underneath this heading, further subdivisions refine the classification. The subcategory "Other" (4412.59.95.00) is provided to capture specific types of plywood that meet the coniferous outer ply criteria but are not otherwise specified or detailed in preceding subheadings. This allows for a granular categorization of various coniferous plywood products based on additional distinguishing features not detailed in the parent descriptions.
