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
