4412.52.31.75 - Other

This HTS category, 4412.52.31.75, encompasses plywood that is not surface covered, or is surface covered with a clear or transparent material that does not obscure the grain, texture, or markings of the face ply. Specifically, it falls under plywood with at least one outer ply of nonconiferous wood, and further specified as blockboard, laminboard, and battenboard that are classified as "Other" within this sub-level. This implies that the material has met all prior hierarchical criteria but does not fit into more specific sub-classifications based on surface treatment or construction if such existed at this precise level of detail.

This specific classification differentiates itself from its sibling, 4412.52.31.61, by exclusion. While the sibling covers plywood that is *not* surface covered, this category, 4412.52.31.75, implies a more nuanced "Other" designation that may include items not explicitly defined by the lack of surface covering or by treatments that do obscure the grain. The "Other" designation here signifies a residual category for plywood meeting all preceding criteria that does not fall into a more narrowly defined group at this level.

As a leaf node, this category does not have further subcategories. Therefore, the classification concludes here. For practical purposes, importers and exporters should ensure their product strictly adheres to the criteria of being plywood, with at least one nonconiferous outer ply, of the blockboard, laminboard, or battenboard construction, and having a surface treatment (or lack thereof) that is not explicitly excluded by any prior or sibling classifications at this stage of the tariff schedule.
