Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If purity below technical grade or contains isomers
Less pure or mixed unsaturated fluorinated hydrocarbons go to the 'Other' category rather than specific statistical suffix.
If formulated as organic refrigerant mixture with additives
Refrigerant gas mixtures with propellants or stabilizers classify under Chapter 38 as formulated products.
If classified as fluorinated butadiene derivative
Certain unsaturated fluorocarbons with diene structures may fall under chlorofluorinated unsaturated hydrocarbons.
