Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If refractory clay composition for high-temperature applications
Refractory bricks designed for furnaces or kilns classify under heading 6902, not general building bricks.
If used as roof tiles rather than wall bricks
Ceramic roof tiles have distinct functional shaping and firing, falling under heading 6905 for roofing elements.
If not fired after shaping or contains cement binders
Articles of plasters or cement, even clay-based, exclude from Chapter 69 per note (b).

Import Tips & Compliance
• Verify firing temperature exceeds 800°C with manufacturer certificates to confirm classification in Chapter 69, avoiding exclusion for unfired products
• Provide documentation on brick dimensions and solidity (no internal voids >20% volume) to distinguish from hollow bricks in 6904.10.00.10
• Test water absorption per ASTM C373; rates over 3% may shift to earthenware categories outside building bricks
