Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If pre-mixed in polyol premix formulations
Foam blowing agent blends with polyols and catalysts classify as Chapter 38 chemical preparations for specific foam manufacturing.
If when foam is already manufactured
Finished polyurethane foam products containing residual HCFC-124 are classified in Chapter 39 plastics, not the blowing agent itself.
If other specified HCFCs in foam applications
Different HCFC isomers used in foam blowing have separate statistical suffixes within the 2903.79 series.
