Import Tips
• Verify firing certification and water absorption test results per ASTM C373 to confirm laboratory-grade porcelain classification
• Include material composition documentation showing high kaolin content for non-porous body to avoid earthenware reclassification
• Ensure lab end-use declaration; mislabeling as tableware risks Chapter 69 exclusions or higher duties
