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
