6904.10.00.10/Heat Insulating Ceramic Solid Building Brick/China

Heat Insulating Ceramic Solid Building Brick from China

A solid ceramic building brick fired after shaping from inorganic nonmetallic materials like clays and lightweight aggregates, designed specifically for heat insulation in construction. It falls under HTS 6904.10.0010 as a solid building brick with thermal insulating properties, meeting Chapter 69 requirements for fired ceramic products not classifiable in headings 6901-6903. Thickness exceeds US note limits for tiles, confirming building brick classification.

Import Tips

• 1

• Provide firing temperature certification (>800°C) to prove Chapter 69 eligibility and exclude unfired articles. 2

• Include thermal conductivity test results (e.g

• ASTM C518) to substantiate 'heat insulating' claim. 3

• Confirm solid construction (no internal voids >3.2cm thick) to avoid reclassification as tiles under 6904 other provisions
