4418.75.40.00 - Having a face ply more than 6 mm in thickness

This HTS category, 4418.75.40.00, specifically classifies multilayer assembled flooring panels where the visible top layer, known as the face ply, possesses a thickness exceeding 6 millimeters. These are finished wood flooring products designed for installation and typically comprise multiple layers bonded together to enhance stability and performance. The defining characteristic for classification here is the substantial thickness of the face ply, indicating a product with a significant wear layer.

It is important to distinguish this category from its sibling, 4418.75.70.00, which covers "Other" multilayer assembled flooring panels. The sibling category would encompass products that do not meet the specified face ply thickness of more than 6 mm. Therefore, the critical differentiator is the precise measurement of the top decorative wood layer.

As a leaf node in the HTS classification system, 4418.75.40.00 does not have further subdivisions. Classification under this code is determined solely by the presence of an assembled flooring panel with a multilayer construction and a face ply measuring greater than 6 mm in thickness. Examples would include engineered wood flooring planks or parquet panels where the top hardwood veneer or solid wood layer meets this specific dimensional requirement.
