6907.22.90.11 - Tiles, the largest surface area of which is capable of being enclosed in a square the side of which is 30 cm or less

This HTS category, 6907.22.90.11, specifically classifies ceramic tiles where the largest surface area can be enclosed within a square with sides of 30 centimeters or less. These tiles are intended for flooring (flags and paving), hearths, or walls. Critically, they fall within the broader group of ceramic flags, paving, hearth or wall tiles that are *not* specifically classified under subheadings 6907.30 or 6907.40.

The defining characteristic of tiles within this sub-classification is their water absorption coefficient. They exhibit a water absorption by weight that exceeds 0.5 percent but does not surpass 10 percent. Furthermore, these tiles are glazed, meaning they have a vitreous coating applied to their surface. This distinguishes them from unglazed tiles that may otherwise share similar physical dimensions.

As a leaf node within the HTS, this category represents the most granular level of classification for these specific ceramic tiles. Therefore, there are no further subcategories to introduce. Classification at this level relies on the precise combination of tile size (largest surface area enclosed in a square of 30 cm or less), their water absorption rate (0.5% to 10%), and the presence of a glazed finish.
