6907.30.10.51 - Other

This HTS category, 6907.30.10.51, specifically covers "Other" mosaic cubes and similar ceramic articles that are unglazed and not those defined as having their largest surface area capable of being enclosed in a square with a side of 30cm or less. These goods are ceramic tesserae intended for decorative or functional mosaic applications, distinct from larger tiles or those with a glazed finish. The "other" designation signifies that these are mosaic units that do not fit the precise dimensional criteria of the sibling category.

Unlike the sibling category 6907.30.10.11, which is characterized by mosaic cubes where the largest surface area is less than or equal to 30cm on its side, this classification applies to mosaic pieces that are either larger than this dimension or are of irregular shapes that do not conform to that specific measurement. The absence of a glaze is a critical distinguishing feature, indicating the ceramic material's natural porous surface.

As this is a leaf node, there are no further subcategories. Classification within this code relies on the precise determination that the goods are unglazed ceramic mosaic cubes or the like, and that they do not meet the specific size criteria outlined in the directly preceding subheading. The focus is on the unglazed nature and the exclusion from more specifically defined mosaic cube dimensions.
