4418.75 - Other, multilayer:

This HTS category, 4418.75, encompasses "Other, multilayer" assembled flooring panels that do not fit into the more specific classifications for bamboo flooring (4418.73) or flooring designed for mosaic patterns (4418.74). These panels are characterized by their construction, featuring multiple layers of wood or wood-based materials adhered together to form a finished flooring product. The defining feature is their multilayer construction, which contributes to stability, durability, and aesthetic appeal.

The key differentiator for 4418.75 lies in its exclusion of specific material or design features that would place it under sibling categories. Unlike 4418.73, these panels are not primarily made of bamboo. Furthermore, they are not specifically designed for mosaic flooring applications as defined under 4418.74. This category acts as a broader classification for multilayered wood flooring panels that do not meet the criteria for more specialized entries.

The subdivisions within 4418.75 further refine the classification based on a critical physical characteristic: the thickness of the top layer, also known as the wear layer. Subcategory 4418.75.40.00 is for panels where this face ply exceeds 6 millimeters in thickness, indicating a potentially more robust or premium construction. The remaining panels, where the face ply is 6 millimeters or less, are classified under 4418.75.70.00. This distinction is important for assessing material value and potential end-use applications.
