6907.23.90.11 - 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 classification pertains to ceramic tiles specifically designed for flooring, hearths, or walls, excluding those classified under subheadings 6907.30 and 6907.40. The key defining characteristic for this category is a water absorption coefficient by weight exceeding 10 percent, indicating a porous ceramic body. Furthermore, these tiles are glazed, meaning they have a vitreous coating applied for decorative and protective purposes. The "Other" designation signifies that these tiles do not fit into any more specific, pre-defined subcategories within the glazed, porous ceramic tile group, based on their dimensions or other distinguishing features.

Within the same hierarchical level, the sibling category 6907.23.90.51, also designated as "Other," likely represents tiles that meet the porous and glazed criteria but might differ in subtle ways not captured by the current node's specific definition. For instance, it could encompass tiles of different sizes or with unique glaze applications not covered by more granular, unlisted sub-classifications. However, without further detail on the distinctions at this level, the primary differentiator remains the specific wording of the official HTS description and any interpretive notes associated with the tariff.

As this is a leaf node within the HTS database, there are no further subcategories to introduce. Therefore, classification within 6907.23.90.11 is determined by meeting all preceding criteria: being a ceramic flag, paving, hearth, or wall tile, having a water absorption coefficient exceeding 10 percent by weight, and being glazed. The final distinguishing feature for inclusion here is the absence of a more specific classification based on dimensions or other characteristics not detailed at this node.
