Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If pure perfluorocarbons
Unmixed PFCs like pure CF4 classify as other fluorine compounds in Chapter 28
If packaged with HCFCs for specific applications
Addition of HCFCs changes classification to the HCFC-containing subheading
If other halogenated industrial gases
Alternative classification for non-HFC/PFC halogen gases used in industry
