Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing hydrogen and classified as saturated acyclic hydrocarbon
Different halogenation level moves to earlier headings in chapter 29 per classification note.
If sold as refrigerant blend (e.g., R-12/134a mix)
Mixtures of isomers or compounds fall outside pure compound classification in chapter 29.
If imported as component in complete refrigeration unit
Assembled equipment classified by function rather than chemical contents.
