99.9% Pure CFC-11 Trichlorofluoromethane
High-purity (99.9%) trichlorofluoromethane, designated CFC-11, is a separate chemically defined organic compound under Chapter 29 note (a), imported under HTS 2903.77.00.10 for its exact perhalogenated fluorochloromethane structure. This specification excludes mixtures or preparations, qualifying it strictly as the base halogenated hydrocarbon. Used in analytical chemistry and calibration gas standards.

Import Tips & Compliance
• Provide GC-MS purity certificate matching ≥99.9%; deviations reclassify to mixture headings
• Declare specific analytical end-use on commercial invoice to qualify for potential research exemptions
• Avoid retail packaging; bulk cylinders only, as consumer packages shift to Chapter 38

Trichlorofluoromethane (CFC-11)
Trichlorofluoromethane, also known as CFC-11, is a perhalogenated acyclic hydrocarbon containing only fluorine and chlorine atoms, specifically one fluorine and three chlorine atoms bonded to a methane backbone. It falls under HTS 2903.77.00.10 as a halogenated derivative of acyclic hydrocarbons with two or more different halogens, precisely matching the chemical definition of trichlorofluoromethane. This compound was historically used in refrigeration and foam blowing but is now primarily traded for destruction or recycling under international agreements.
R-11 Refrigerant Trichlorofluoromethane
R-11, the refrigerant grade designation for trichlorofluoromethane (CFC-11), is a colorless, non-flammable gas classified under HTS 2903.77.00.10 due to its precise chemical structure as a fluorochlorinated acyclic hydrocarbon. This product matches the heading's specification for perhalogenated compounds containing only fluorine and chlorine. Primarily imported today for reclamation, recycling, or controlled destruction programs.
