6907.30.10 - Unglazed

This HTS category encompasses ceramic mosaic cubes and similar articles used for decorative or functional surfacing purposes. These items are distinguished from ceramic flags, paving, hearth, or wall tiles by their smaller, modular construction, specifically designed to create mosaic patterns. They are further differentiated from other mosaic materials by their ceramic composition.

Crucially, this subheading specifically pertains to *unglazed* mosaic cubes and the like. This distinguishes it from its sibling category, which covers glazed versions of similar articles. The absence of a glaze is a key determinant for classification under this heading, implying a natural ceramic finish or one that has undergone a firing process without the application of a vitreous coating.

The subcategories within this heading further refine classification based on the dimensions and presentation of the mosaic pieces. Subheading 6907.30.10.05 specifically addresses cubes and similar items where the largest surface area can be enclosed within a square with a side of less than 7 cm. The "Other" subcategory would then encompass larger mosaic pieces or those not meeting the specific dimensional criteria of the preceding subheading.
