HCFC-123 (2,2-Dichloro-1,1,1-trifluoroethane)
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 Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If formulated as a refrigerant blend with additives like lubricants
Mixtures containing HCFC-123 with other substances for specific refrigeration use fall under prepared chemical preparations rather than pure compounds.
If imported as an organic composite solvent mixture
Blends of HCFC-123 with other solvents for cleaning applications are classified as organic composite solvents, not individual halogenated hydrocarbons.
If containing only chlorofluorine but different isomer ratio
Other chlorodifluoroethanes or isomers with different halogen positioning fall under the preceding subheading for similar but distinct compounds.

Import Tips & Compliance
• 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
