HCFC-123 (2,2-Dichloro-1,1,1-trifluoroethane) from Mexico

Pure HCFC-123 is a hydrochlorofluorocarbon used primarily as a refrigerant in low-pressure centrifugal chillers for commercial air conditioning systems. This halogenated acyclic hydrocarbon contains both chlorine and fluorine atoms attached to its ethane backbone, fitting precisely under HTS 2903.72.0100. It is produced as a separate chemically defined organic compound without impurities that would alter its classification.

Import Tips

Verify EPA compliance under the Montreal Protocol as HCFC-123 imports are restricted and phased out; obtain necessary allocations or exemptions

Provide detailed purity certificates (typically >99.9%) and safety data sheets confirming chemical identity to avoid misclassification

Label containers with UN 1029 hazmat markings and ensure proper documentation for transport under DOT regulations
