Import Tips & Compliance
• Verify porcelain composition via ASTM C373 water absorption test (≤0.5%) and provide firing certificates to confirm Chapter 69 eligibility
• Ensure country-of-origin marking on packaging; common pitfall is misclassifying glazed earthenware as porcelain
• Include installation specs in documentation to avoid reclassification as building materials under Chapter 68
