Trichlorotrifluoroethane Calibration Standard
Certified reference material of CFC-113 in solvent matrix for gas chromatography calibration. The pure trichlorotrifluoroethane component classifies under HTS 2903.77.00.20 as a chemically defined perhalogenated compound. Diluted forms remain classified to the active compound per Chapter 29 note (d).

Import Tips & Compliance
• Specify concentration and matrix solvent on invoice; remains classified to CFC if meeting chapter note (d)
• Include NIST traceability certificate for laboratory standards
• Declare as 'chemical reference standard' not 'refrigerant' to avoid regulatory confusion
Related Products under HTS 2903.77.00.20
1,1,1-Trichloro-2,2,2-trifluoroethane (CFC-113a)
This is a perhalogenated acyclic hydrocarbon containing only fluorine and chlorine atoms, specifically a trichlorotrifluoroethane isomer. It falls under HTS 2903.77.00.20 as a halogenated derivative of hydrocarbons with two or more different halogens, perhalogenated only with F and Cl. Historically used as a refrigerant and solvent, its import is now heavily regulated due to ozone depletion.
1,1,2-Trichloro-1,2,2-trifluoroethane (CFC-113)
CFC-113 is a specific trichlorotrifluoroethane isomer, fully halogenated with three chlorine and three fluorine atoms on an ethane backbone. Classified under HTS 2903.77.00.20 as it matches the description of perhalogenated acyclic hydrocarbons with only F and Cl. Primarily used in precision cleaning of electronics before phase-out.
