6907.30.90 - Other

This HTS subcategory, 6907.30.90, encompasses mosaic cubes and similar ceramic articles that are glazed and do not fall under the more specific criteria of subheading 6907.40. These are decorative ceramic pieces designed for use in mosaics or as finishing elements on walls and floors. The key characteristic is their small size and their application in creating intricate patterns.

Unlike sibling categories that might differentiate based on specific dimensions or backing, this classification broadly covers "other" glazed mosaic cubes. This implies that once a ceramic article is identified as a mosaic cube or similar, is glazed, and does not meet the detailed specifications of other subheadings, it is directed here. The emphasis remains on the material (ceramic), form (mosaic cube or similar), and surface treatment (glazed).

Within this category, further distinctions are made based on size. Subheading 6907.30.90.11 specifically captures cubes and similar pieces where the largest surface area can be enclosed within a square of 30 cm or less, offering a more granular classification for smaller mosaic units. The remaining items, classified under 6907.30.90.51, represent those glazed mosaic cubes and the like that do not meet the size criteria of the preceding subheading, thus providing a residual classification for other appropriately sized mosaic components.
