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.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If when imported as a component in non-hazardous chemical preparations or mixtures
Mixtures containing trichlorofluoromethane exceeding certain concentrations may classify under prepared binders or chemical products rather than pure compounds.
If specifically prepared as a reaction initiator for high polymers (e.g., PVC production)
Chapter notes prioritize end-use classification; catalysts and reaction initiators take precedence over base chemical classification.
If for other perhalogenated fluorochlorocarbons not specifically enumerated as trichlorofluoromethane
Statistical breakout applies only to exact trichlorofluoromethane; isomers or close analogs fall in residual 'other' category.

Import Tips & Compliance
• Obtain EPA import certification under the Montreal Protocol Clean Air Act regulations prior to shipment, as this ozone-depleting substance requires specific approvals
• Include detailed chemical purity analysis and quantity declarations; ensure compliance with Basel Convention if classified as hazardous waste for destruction
• Verify end-use declarations to avoid diversion; common pitfall is insufficient quarantine facility documentation for temporary storage

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.
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.
