4412.33.06 - With a face ply of birch (Betula spp.)

This HTS category, 4412.33.06, specifically classifies plywood and similar laminated wood panels where at least one outer ply is composed of birch (Betula spp.). These panels must consist solely of wood sheets (excluding bamboo), with each ply not exceeding 6 mm in thickness. Furthermore, the classification applies to products that are either not surface-covered or are covered with a transparent material that allows the grain, texture, and markings of the face ply to be clearly visible.

This classification is distinguished from its siblings by the specific species of wood designated for the face ply. For instance, HTS code 4412.33.26 applies to panels with a face ply of walnut (Juglans spp.), while 4412.33.32 covers other similar panels not otherwise specified. Therefore, the presence of birch as the face ply is the defining characteristic for this particular code.

The subcategories under 4412.33.06 further refine the classification based on the physical dimensions of the panels. The code 4412.33.06.20 specifically applies to panels not exceeding 3.6 mm in thickness, 1.2 m in width, and 2.2 m in length. All other birch-faced plywood panels fitting the broader description but not meeting these specific dimensional criteria fall under the "Other" subcategory.
