6907.22.20.00 - Having not over 3229 tiles per square meter, most of which have faces bounded entirely by straight lines

This classification pertains to glazed ceramic tiles where the largest surface area is capable of being enclosed within a square with sides measuring less than 7 centimeters. These are typically smaller decorative or functional tiles, often referred to as mosaic tiles or accent pieces, designed for use in various tiling applications. The defining characteristic for inclusion here is the geometric constraint on the tile's largest dimension.

While this category focuses on smaller glazed ceramic tiles, it is distinguished from its sibling, "Other," which would encompass glazed ceramic tiles of similar water absorption but with a largest surface area requiring a square with sides of 7 cm or greater. This distinction is crucial for accurate tariff application and allows for the segregation of smaller, often more intricate, ceramic pieces.

As this is a leaf node, there are no further subcategories. Classification at this level is determined by the combination of glazed finish, water absorption coefficient, and the specific dimensional limitation of the tile's largest surface area. Examples might include small decorative mosaic tiles used for intricate patterns, borders, or accents in kitchens, bathrooms, or artistic installations where precise sizing is a key feature.
