4412.91.10 - With a face ply of birch (Betula spp.)

This classification, HTS Code 4412.91.10, specifically designates plywood where at least one of the outer plies is composed of birch (Betula spp.). This category falls under a broader group of "Other" plywood, excluding those with a tropical wood face ply at this specific juncture. The defining characteristic is the use of birch as a face ply, distinguishing it from other plywood types that might utilize different wood species for their outer layers.

Within the context of "Plywood, veneered panels and similar laminated wood," this HTS code focuses on plywood that is either not surface-covered or is covered with a clear or transparent material that allows the grain, texture, or markings of the face ply to remain visible. This distinction is crucial for accurate classification, ensuring that finished or treated plywoods with obscured face plies are directed to other appropriate headings.

The subcategories under this HTS code further refine the classification based on the physical dimensions of the plywood panels. Specifically, 4412.91.10.20 addresses panels meeting precise thickness and width/length limitations, while an "Other" subcategory exists to capture plywood panels that do not fit these specific dimensional criteria. This granular approach to classification allows for more precise import/export management based on product specifications.
