Small Stone Tiles, Mosaic Cubes & Colored Stone Granules or Powder

The test is whether the largest face of the tile or cube can be enclosed within a square with sides under 7 cm. If the tile's largest surface exceeds that square, it falls outside 6802.10 and into the broader worked monumental or building stone headings (6802.21–6802.99) based on stone type and surface treatment. Measuring the largest face — not the perimeter — is the operative step.

Trade remedy exposure depends on the specific stone type and country of origin. Importers of Chinese-origin stone products should verify whether active Section 301 or antidumping orders cover their specific granule or powder product, as coverage can vary by stone species and processing level. A binding classification ruling or broker review is advisable for ambiguous products.
