Trichlorofluoromethane (CFC-11) from China
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 Tips
• 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
