Vitreous glass mosaic tiles are classified as glass articles under this heading, while ceramic mosaic tiles fall under a separate ceramic products heading. The material composition — glass versus fired ceramic — is the determining factor, not the tile's size, shape, or decorative application. Importers sourcing mixed-material mosaic assortments should ensure each material type is separately identified on the commercial invoice.

The primary buyers are architectural and interior design firms specifying decorative wall and floor surfaces, swimming pool tile contractors, and artists or craftspeople working in mosaic media. Demand is closely tied to residential and commercial construction activity, making import volumes sensitive to building-sector cycles. Custom color and finish specifications from designers often drive sourcing decisions as much as price.
