Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If non-heated, mechanical liner only
Unheated liners without electrical elements classify as mechanical parts under 9027.90.5230 for gas chromatographs.
If imported solely as quartz lab tubes
Standalone quartz liners without GC-specific heating or fittings are laboratory glassware of 7017, not instrument accessories.
If principally for laboratory heating ovens
Heating elements suitable mainly for general lab ovens (not GC-specific) shift to parts of laboratory machinery in 8419.

Import Tips & Compliance
• Include material safety data sheets for glass and heating components; confirm voltage compatibility (e.g
• 110V vs 220V); avoid bulk packaging that suggests non-lab use to prevent reclassification
