6907.30 - Mosaic cubes and the like, other than those of subheading 6907.40:

This HTS category, 6907.30, specifically covers ceramic mosaic cubes and similar small pieces of ceramic material, intended for decorative or functional purposes such as creating mosaic patterns on surfaces. This can include individual cubes or small tesserae, whether or not they are pre-assembled onto a backing material for ease of installation. The key characteristic is their form as small, modular units designed to be combined to form larger designs.

Distinguishing this category from its siblings is crucial for accurate classification. Unlike the flags, paving, hearth, or wall tiles found in subheading 6907.20, which are typically larger formats for covering surfaces, 6907.30 focuses on the smaller, mosaic-style pieces. It also differs from finishing ceramics under 6907.40, which generally refers to border pieces, moldings, or other specialized decorative elements that complete an installation rather than forming the primary mosaic pattern.

The subcategories within 6907.30 further refine classification based on surface treatment. "Unglazed" (6907.30.10) applies to mosaic cubes that have not undergone a glazing process, retaining their natural ceramic finish. The alternative, "Glazed," encompasses mosaic cubes that have been coated with a vitreous glaze, offering a variety of colors, finishes, and increased durability or water resistance. This distinction is important for understanding the aesthetic and functional properties of the mosaic material.
