Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If refractory with high melting point materials
Refractory bricks/tiles for extreme heat go to 6902, not finishing ceramics.
If water absorption ≤0.5%
Very low absorption ceramic tiles classify separately in 6907.40.
If sanitary fixture components
Bathroom ceramic fittings like surrounds shift to 6910 if functional purpose changes.

Import Tips & Compliance
• Specify hearth use in entry docs; distinguishes from flooring to affirm tile classification
• Ensure no metallic content > exclusions; pure ceramic composition avoids Chapter 82 tools
• Batch-test absorption if mixed production; averages must exceed 10% threshold
