Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If also contains CFCs or HCFCs
Mixtures containing both HBFCs AND CFCs/HCFCs classify under the broader 3827.20 CFC subheading.
If imported as chemical waste
Reclaimed/recycled HBFC refrigerants for destruction classify as hazardous chemical wastes.
If pure HBFC refrigerant gas
Unmixed, liquefied HBFC refrigerants without additives fall under pure chlorofluorocarbon headings.
