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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If when imported in bulk quantities exceeding statistical breakpoints
Different statistical suffixes apply based on purity grade or container size within same chemical heading.
If recovered/reclaimed and containing impurities from recycling processes
Reclaimed CFCs with solvents or contaminants classify as chemical preparations rather than pure compounds.

Import Tips & Compliance
• Require Montreal Protocol Essential Use Nomination or destruction certification; imports without pre-approval face seizure
• Ship as UN 1029 hazardous material with proper DOT placarding; temperature-controlled containers mandatory for liquefied gas
• Maintain chain-of-custody documentation proving legitimate recycling/destruction end-use to prevent illegal stockpiling penalties

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.
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.
