Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If generic liners not branded for specific GC instruments
Moves to laboratory glassware heading when not dedicated to Chapter 90 apparatus.
If considered parts of laboratory distillation apparatus
GC components sometimes overlap with distillation equipment in 8419 if not analytical-specific.
If parts specifically for 9027.20 chromatographs
Subheading specificity within 9027.90 depends on exact instrument category.
