Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If made of ceramic other than porcelain or china
Non-porcelain ceramics for lab use shift to 'other' ceramic wares under 6909.90, as porcelain requires specific white, low-absorption body.
If not exclusively for laboratory or technical end-use
General ceramic articles of porcelain not specialized for lab/chemical uses fall under Chapter 69 household/laboratory/other provisions.
If made of laboratory glassware instead of ceramic
Glass lab equipment is excluded from Chapter 69; only fired ceramic qualifies here.

Import Tips & Compliance
• 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
