Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing >10% alumina or silica
High-alumina tiles excluded to 6907.30 regardless of absorption or glaze.
If lab/decorative porcelain quality
Lower absorption (<0.5%) porcelain wall tiles go to Chapter 69 tableware/labs section.
If agglomerated or cut from natural stone
Not clay-fired ceramics; worked natural stone tiles classify under Chapter 68.

Import Tips & Compliance
• Provide absorption test results upfront; exceeding 10% keeps it from porcelain/stoneware reclassification
• Document as 'other' unglazed tiles—not mosaic cubes—to stay in .51 subheading
• Check for backing; if on mesh backing as mosaics, may shift despite high absorption
