Import Tips
• Verify firing temperature exceeds 800°C and provide lab test results for water absorption under 0.5% to confirm porcelain classification
• Include certificates of chemical resistance and thermal shock testing to avoid reclassification as common wares
• Label clearly as 'laboratory use only' to prevent misclassification into Chapter 69 exclusions like tableware
