Import Tips
• Verify clay content exceeds 50% and test thermal resistance to confirm classification under 3816.00.20.10
• Include material safety data sheets (MSDS) and firing temperature specs in documentation to avoid reclassification
• Watch for mislabeling as plain clay (3801), which has different duties; ensure 'refractory composition' labeling
