Import Tips

Verify porcelain composition via ASTM C373 water absorption test (<0.5%) to confirm classification and avoid reclassification as earthenware

Provide lab certification or end-use statements to support technical use exemption from general tableware headings

Watch for misclassification as lab glassware (7017); porcelain must be fired ceramic per Chapter 69 notes
