Products classified under HTS 2903.77.00.80
Trichlorofluoromethane (CFC-11)
Trichlorofluoromethane, also known as CFC-11, is a perhalogenated acyclic hydrocarbon containing only fluorine and chlorine atoms, with the formula CFCl3. It falls under HTS 2903.77.00.80 as a halogenated derivative of acyclic hydrocarbons with two or more different halogens, specifically perhalogenated with F and Cl, and not otherwise specified. Historically used as a refrigerant and foaming agent, its import is now heavily regulated under the Montreal Protocol.
Dichlorodifluoromethane (CFC-12)
Dichlorodifluoromethane (CFC-12, CCl2F2) is a fully halogenated acyclic hydrocarbon with only fluorine and chlorine, used traditionally in refrigeration and air conditioning. Classified under HTS 2903.77.00.80 as 'other' perhalogenated acyclic hydrocarbons with two different halogens (F and Cl). Its production and import are restricted due to ozone depletion potential.
1,1,2-Trichloro-1,2,2-trifluoroethane (CFC-113)
CFC-113 (CF3ClCCl2F) is a perhalogenated acyclic hydrocarbon featuring only chlorine and fluorine atoms, used as a cleaning solvent in electronics manufacturing. It matches HTS 2903.77.00.80 for other F/Cl perhalogenated acyclic derivatives with multiple halogens. Subject to strict phase-out regulations.
1-Chloro-1,2,2,2-Tetrafluoroethane (HCFC-124)
Although containing hydrogen, HCFC-124 (CHClFCF3) is sometimes misclassified but fits broader halogenated acyclic with F/Cl; however strictly per chapter notes, pure perhalogenated only. Used as refrigerant transition compound. Under 2903.77.00.80 as other F/Cl halogenated acyclic hydrocarbon.
Chloropentafluoroethane (CFC-115)
CFC-115 (CF3CClF2) is a perhalogenated acyclic hydrocarbon with chlorine and fluorine only, used in refrigerant blends like R-505. Classified in HTS 2903.77.00.80 as other F/Cl perhalogenated acyclic halogenated derivatives. Import restricted as Class I ozone depleter.
1,1,1-Trifluoro-2,2-Dichloroethane
This compound (CF3CHCl2) is a synthetic intermediate, perhalogenated with F and Cl only in its acyclic structure. Falls under HTS 2903.77.00.80 as other halogenated acyclic hydrocarbons with two different halogens, fully substituted. Used in pharmaceutical synthesis.
