Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If pre-mixed with lubricants for medical compressor systems
Refrigerant oils and additives create a mixture classifiable in Chapter 38 rather than pure HFC-143.
If when charged into medical freezer evaporators
Parts of refrigeration machinery containing refrigerant are classified under Chapter 84 evaporators/condensers.
If falsely declared as immunological product diluent
Chapter 29 note explicitly excludes immunological products of heading 3002 from chemical compound classification.
