Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If marketed as decorative rather than functional ferrule
Porcelain articles for ornamental use shift to tableware/decorative headings based on principal use.
If functioning primarily as insulating fittings
Chapter 69 excludes electrical insulators classified under 8546/8547.
If made from polymer ceramics not fired above 800°C
Unfired resin-cured articles fall under plastics Chapter 39 per Chapter 69 note (b).

Import Tips & Compliance
• 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
