6907.22.90 - Other

This category encompasses ceramic flags, paving, hearth, and wall tiles that are not specifically classified under subheadings 6907.30 or 6907.40. It further refines the classification by focusing on tiles with a water absorption coefficient by weight exceeding 0.5 percent but not exceeding 10 percent. These are specifically glazed ceramic tiles, indicating they have an outer coating of glass-like material applied to their surface for aesthetic appeal and increased durability.

Distinguishing this category from its sibling, "The largest surface area of which is capable of being enclosed in a square the side of which is less than 7 cm," is crucial. While the sibling category focuses on the *size* of the tile (specifically smaller tiles), this category is defined by its *water absorption properties* and the presence of a glaze, regardless of its overall dimensions. Therefore, a glazed tile with a water absorption rate within the specified range will fall here, even if it is larger than the size limitation of the sibling category.

Within this "Glazed" subcategory, further distinctions are made to account for variations in tile dimensions. The subcategory 6907.22.90.11 covers tiles where the largest surface area can be enclosed within a square with a side length of 30 cm or less, indicating smaller format glazed tiles. Conversely, the subcategory 6907.22.90.51, "Other," is reserved for glazed ceramic tiles with the defined water absorption characteristics that *do not* meet the size criteria of the preceding subcategory, thus encompassing larger format glazed tiles.
