Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If pure HCFC-123 imported separately
Unmixed HCFC-123 classifies under its specific chemical subheading rather than mixtures.
If contains other restricted halogenated compounds listed in 3824 notes
Mixtures with specific toxic halogen derivatives fall under chemical preparations in 3824.
If when sold as industrial cleaning solvent mixture
End-use as organic solvent rather than blowing agent moves to composite solvents heading.
