Products classified under HTS 2903.72.01.00
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.
Dichlorotrifluoroethane USP Grade (HCFC-123)
Pharmaceutical-grade HCFC-123 meeting USP standards for use as a propellant in metered dose inhalers. This pure, chemically defined compound is a halogenated derivative of acyclic ethane with both chlorine and fluorine, squarely within HTS 2903.72.0100 scope. Supplied in small cylinders with stabilizer for medical applications.
2,2-Dichloro-1,1,1-trifluoroethane Lab Grade
High-purity laboratory reagent HCFC-123 used for organic synthesis and analytical standards. This chemically defined compound with formula C2HCl2F3 is a halogenated acyclic hydrocarbon under HTS 2903.72.0100. Supplied in 1L lecture bottles with anti-dusting agent for safety.
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.
HCFC-123 Chiller Refrigerant Cylinder
50 lb disposable cylinder containing pure HCFC-123 for centrifugal chiller retrofits. As a separate chemically defined dichlorotrifluoroethane, it matches HTS 2903.72.0100 for halogenated acyclic hydrocarbons with mixed halogens. Includes minimal stabilizer per chapter note (f).
