Products classified under HTS 2903.77.00.30
Dichlorotetrafluoroethane (CFC-114) Refrigerant Gas
Dichlorotetrafluoroethane (CFC-114), a perhalogenated acyclic hydrocarbon with only fluorine and chlorine, is classified under HTS 2903.77.00.30 as a halogenated derivative containing two different halogens. This chemical compound was historically used as a refrigerant in industrial cooling systems and as a blowing agent in foam production. Its classification is based on chapter 29 notes for separate chemically defined organic compounds.
CFC-114 Blowing Agent for Polyurethane Foam
CFC-114 serves as a blowing agent in rigid polyurethane foam production, fitting HTS 2903.77.00.30 due to its status as a separate chemically defined perhalogenated acyclic hydrocarbon with fluorine and chlorine only. This classification adheres to Chapter 29's scope for halogenated derivatives. It was commonly used in insulation foams before phase-out.
Medical Grade CFC-114 Aerosol Propellant
High-purity dichlorotetrafluoroethane (CFC-114) used as a propellant in pharmaceutical aerosols is classified under HTS 2903.77.00.30 as a chemically defined halogenated acyclic hydrocarbon. Chapter 29 notes confirm its inclusion as a separate organic compound, excluding immunological products. It was used in metered-dose inhalers before HFA replacements.
CFC-114 Calibration Gas Standard
Dichlorotetrafluoroethane in precise concentrations for gas chromatography calibration falls under HTS 2903.77.00.30 as a chemically defined compound per Chapter 29 note (a). Dissolved or mixed only as allowed in notes (d)-(g) for safety/transport. Used in environmental labs to calibrate ozone-depleting gas detectors.
Recycled CFC-114 Refrigerant Blend Base
Reclaimed dichlorotetrafluoroethane (CFC-114) from recycled refrigerants, purified to chemical specification, is classified in HTS 2903.77.00.30 as a separate organic compound. Meets Chapter 29 criteria despite recycling origin, provided impurities are minimal.
CFC-114 Dielectric Fluid
CFC-114 used as an electrical insulating fluid in high-voltage equipment is a perhalogenated acyclic hydrocarbon under HTS 2903.77.00.30. Classified per Chapter 29 for chemically defined halogenated derivatives, not as finished electrical apparatus.
Research Grade CFC-114 for Atmospheric Studies
High-purity CFC-114 for scientific research on stratospheric ozone is classified under HTS 2903.77.00.30 as a halogenated derivative of acyclic hydrocarbons. Chapter 29 notes support classification of pure organic compounds for lab use.
