Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If HCFC-only without any CFCs
Absence of CFCs shifts to other halogenated mixtures subheading.
If pre-polymerized into foam chemical
If chemically modified into polymers, it becomes Chapter 39 plastics.
If classified as organic derivative intermediate
Pure intermediates may fall under Chapter 29 if not final mixture.
