Import Tips
• Include technical drawings showing fiber channel opening and exact measurements for Customs verification
• Test and certify water absorption <0.5% per ASTM C373 to confirm porcelain/china status under U.S. notes
• Avoid bulk packaging that suggests parts for assembly abroad, which could trigger anti-dumping scrutiny
