6907.21.10.51 - Other 🖩

This HTS classification, 6907.21.10.51, pertains to "Other" ceramic flags, paving, hearth, or wall tiles that are unglazed and have a water absorption coefficient by weight not exceeding 0.5%. These are essentially ceramic tiles that are not glazed and are designed for flooring, covering walls, or as hearth components, with a very low porosity. The key defining characteristic is their inherent material property of minimal water absorption, indicating a dense and vitreous ceramic body.

This category is distinguished from its sibling, 6907.21.10.11, by the size of the tile. While 6907.21.10.11 specifically covers tiles where the largest surface area can be enclosed by a square with sides of 30 cm or less, this category, 6907.21.10.51, encompasses all other unglazed, low-porosity tiles that *exceed* this size limitation. Therefore, larger format tiles falling under these other physical and material characteristics would be classified here.

As this is a leaf node within the HTS structure, there are no further subcategories. The classification is finalized at this level, meaning that any ceramic flag, paving, hearth, or wall tile meeting the criteria of being unglazed, having a water absorption coefficient not exceeding 0.5%, and not falling under the specific size exclusion of its sibling, is classified under 6907.21.10.51.
