4412.52.51.00 - Other

This HTS classification covers "other" types of blockboard, laminboard, and battenboard that do not fall into more specific subcategories. These are composite wood panels characterized by a core constructed from blocks, strips, or battens of wood, which are then sandwiched between outer layers (veneers). The defining feature of this particular category is that at least one of the outer plies is made from nonconiferous wood, such as tropical hardwoods or domestic hardwoods like oak or maple. The construction method involves gluing these layers together under pressure, resulting in a stable and strong panel.

To distinguish this category from its sibling, "Plywood," it's important to note the core construction. While plywood typically consists of multiple thin veneers of wood (often from coniferous or nonconiferous species) cross-laminated with their grain oriented at angles to each other, the products under 4412.52.51.00 utilize a core made of larger wood pieces (blocks, strips, or battens). This fundamental difference in core material and construction is the primary differentiator from general plywood.

As this HTS code represents a leaf node, there are no further subcategories. Therefore, the focus for classification within this entry is on the precise definition of blockboard, laminboard, and battenboard, with the critical condition that at least one outer ply is of nonconiferous wood, and that it does not meet the criteria for any more specific classification within its parent chapter. Examples of products fitting this description could include panels used in furniture manufacturing, cabinetry, or decorative applications where the aesthetic or structural properties of hardwoods are desired for the visible surfaces.
