4418.73.40.00 - Having a face ply more than 6 mm in thickness

This HTS classification, 4418.73.40.00, specifically covers multilayer assembled flooring panels where the top ply, also known as the wear layer, is more than 6 millimeters in thickness. These flooring panels are constructed with multiple layers of wood or wood-based materials, engineered for stability and durability. The defining characteristic for this category is the substantial thickness of the uppermost layer, which provides a robust surface for wear and tear.

This category is distinguished from its sibling category, "Other," under 4418.73.40, by the specific requirement for the face ply to exceed 6 mm in thickness. While both might be multilayer assembled flooring panels of bamboo or with a bamboo top layer, this subcategory narrows the focus to those with a significantly thicker wear layer, implying potentially greater longevity or a specific aesthetic or structural quality. The "Other" sibling would encompass multilayer panels with a wear layer of 6 mm or less.

As this is a leaf node in the HTS classification, there are no further subdivisions. Classification within 4418.73.40.00 is determined solely by the multilayer construction of the assembled flooring panel and the face ply thickness exceeding 6 mm, in conjunction with the requirement for bamboo to be present in the construction, typically as the wear layer. Importers should ensure their product meets this specific dimension to accurately classify their goods.
