Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If when pre-filled in complete pharmaceutical inhalers
Finished medicinal inhalers containing HCFC-124 propellant are classified in Chapter 30 as medicaments, not bulk chemical compounds.
If fluorinated without chlorine (HFC propellants)
Hydrofluorocarbons (HFCs) lacking chlorine like HFC-134a fall under different subheadings in 2903.39, while HCFCs with Cl remain in 2903.79.
If pharmaceutical-grade with USP stabilizers
Medical propellants with added stabilizers beyond Chapter 29 allowances may classify as chemical preparations in 3824 rather than pure compounds.
