R-123 Refrigerant (HCFC-123)
Industrial-grade R-123 refrigerant, chemically identical to dichlorotrifluoroethane, supplied in 100 lb cylinders for chiller systems. Classified under HTS 2903.72.0100 as a separate chemically defined halogenated acyclic hydrocarbon with two different halogens (chlorine and fluorine). Meets ARI purity standards for HVAC applications.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If fluorinated but without chlorine substitution
Pure hydrofluoroethane isomers without halogen diversity beyond fluorine classify under other fluorinated hydrocarbons.
If sold as fire-extinguishing composition
HCFC-123 mixtures specifically prepared for fire suppression fall under chemical preparations for firefighting.
If heavily diluted in hydrocarbon solvent base
Petroleum-based mixtures with minor HCFC content may classify as synthetic saturated acyclic hydrocarbons.

Import Tips & Compliance
• Include EPA allocation certificates since HCFC imports require quotas; non-compliance leads to seizure
• Specify exact chemical composition and CAS number (306-83-2) on commercial invoice to confirm HTS classification
