Import Tips
• Verify firing temperature certification to confirm Chapter 69 eligibility and avoid exclusion under note (b)
• Provide lab end-use documentation to support technical classification over general tableware
• Test water absorption per ASTM C373 to distinguish porcelain from earthenware if challenged
