Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If HFC-125 content falls below 40% but contains other specified HFCs
Lower HFC-125 concentration moves to general 'other HFC mixtures' subheading.
If for unblended HFC-134a component if separated before import
Individual fluorinated hydrocarbons classify under chemical compound headings in Chapter 29.
