Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If pure HCFC-22 without HFC additives
Single halogenated derivative without mixture classification goes to specific 2903.71 subheading.
If contaminated with any CFC compounds
Any CFC presence, even trace, requires classification under CFC-containing mixtures in 3827.31.
If primarily fluorinated hydrocarbon without chlorine
HFC-only blends lacking chlorine shift to other fluorocarbon derivatives under 2903.39.
