6907.21.20.00 - Having not over 3229 tiles per square meter, most of which have faces bounded entirely by straight lines 🖩

This HTS classification covers ceramic flags, paving, hearth, and wall tiles that are glazed and have a water absorption coefficient by weight not exceeding 0.5%. Specifically, it applies to tiles where the largest surface area is capable of being enclosed in a square with a side length less than 7 centimeters. These tiles are characterized by having not over 3,229 tiles per square meter, with most of their faces bounded entirely by straight lines. They are intended for decorative and functional applications, such as flooring, wall coverings, and hearth surrounds, and are a subcategory of glazed ceramic tiles with specific dimensional limitations.

This category is distinguished from its sibling, "Other," which would encompass glazed ceramic tiles meeting the water absorption criteria but *not* having their largest surface area capable of being enclosed in a square with a side less than 7 cm. In essence, this heading zeroes in on smaller-format glazed ceramic tiles, often referred to as mosaics or smaller decorative tiles, that meet stringent technical requirements for water absorption.

As this is a leaf node, there are no further subcategories. The classification is definitive for glazed ceramic tiles of this specific size and water absorption characteristic. Practical classification relies on measuring the dimensions of the largest surface of the tile to determine if it fits within the specified square constraint and verifying the glazed finish and water absorption coefficient through testing or supplier documentation.
