Trichlorofluoromethane (CFC-11)
Trichlorofluoromethane, also known as CFC-11, is a perhalogenated acyclic hydrocarbon containing only fluorine and chlorine atoms, fully substituted on its carbon chain. This chemical falls under HTS 2903.77.00 as a halogenated derivative of acyclic hydrocarbons with two or more different halogens, specifically perhalogenated with F and Cl. It was historically used as a refrigerant and foaming agent but is now largely phased out due to ozone depletion.
Dichlorodifluoromethane (CFC-12)
Dichlorodifluoromethane (CFC-12) is a fully halogenated methane derivative containing two chlorine and two fluorine atoms, meeting the perhalogenated criteria of HTS 2903.77.00. As an acyclic hydrocarbon derivative with exactly two different halogens (F and Cl), it qualifies precisely under this heading. Commonly known as R-12, it was widely used in refrigeration and air conditioning systems.
1,1,2-Trichloro-1,2,2-trifluoroethane (CFC-113)
CFC-113 is a perhalogenated ethane derivative with three chlorine and three fluorine atoms, fully substituted without hydrogen, fitting HTS 2903.77.00 criteria. This acyclic hydrocarbon halogenated with only F and Cl represents classic ozone-depleting substances from the chlorofluorocarbon family. It was used as a solvent in electronics cleaning and precision degreasing.
Chloropentafluoroethane (CFC-115)
CFC-115 (1-chloro-1,1,2,2,2-pentafluoroethane) is perhalogenated with one Cl and five F atoms, qualifying under HTS 2903.77.00 for acyclic F/Cl-only compounds. This fully substituted ethane derivative was used as a component in refrigerant blends. Its classification follows Chapter 29 rules prioritizing latest numerical heading for multi-halogen compounds.
1,1,1-Trichloro-2,2,2-trifluoroethane (CFC-113a)
CFC-113a is the isomer of CFC-113, featuring three Cl on carbon 1 and three F on carbon 2, fully perhalogenated per HTS 2903.77.00. This acyclic ethane derivative with exclusively F and Cl atoms was used in solvent applications. Chapter notes confirm classification of isomer mixtures under the same heading.
Pentachlorofluoroethane
Pentachlorofluoroethane (C2Cl5F) represents the extreme chlorine-rich end of perhalogenated ethanes under HTS 2903.77.00. This acyclic hydrocarbon is fully substituted with five Cl and one F atoms only. Used in specialized chemical synthesis and formerly as intermediates.
