Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If pure HFC-32 component imported separately
Individual fluorocarbons like difluoromethane classify under specific Chapter 29 subheadings.
If packaged as consumer-ready refrigerant kit with additives
Prepared chemical kits with accessories may shift to 'other chemical preparations'.
If pre-charged in refrigeration equipment
Halogenated mixtures incorporated into finished appliances classify with the equipment.
