4412.51.10 - With a face ply of birch (Betula spp.)

This classification, HTS Code 4412.51.10, specifically covers plywood that has a face ply composed of birch (Betula spp.). This designation is crucial for distinguishing it within the broader category of plywood, veneered panels, and similar laminated wood products, particularly those that are not surface covered or are covered with transparent materials. The defining characteristic here is the specific wood species forming the visible outer layer.

Within the context of "Plywood: Not surface covered, or surface covered with a clear or transparent material which does not obscure the grain, texture or markings of the face ply," this HTS code carves out a specific niche based on the birch face veneer. It is differentiated from sibling categories by the explicit requirement of birch as the primary face material. Other similar products at this level, not explicitly listed with a birch face, would fall under different subheadings.

The subcategories under 4412.51.10 further refine the classification based on the surface treatment. HTS 4412.51.10.30 applies to plywood with a birch face ply that is entirely uncoated or treated with a transparent material that allows the natural grain and texture of the birch to be clearly visible. Conversely, HTS 4412.51.10.50 encompasses other birch-faced plywood within this broader group that may have different surface treatments or characteristics not meeting the criteria for the "Not surface covered" designation.
