Trichlorofluoromethane (CFC-11)
Trichlorofluoromethane, also known as CFC-11, is a perhalogenated acyclic hydrocarbon containing only fluorine and chlorine atoms, fully substituted on its carbon chain. This chemical falls under HTS 2903.77.00 as a halogenated derivative of acyclic hydrocarbons with two or more different halogens, specifically perhalogenated with F and Cl. It was historically used as a refrigerant and foaming agent but is now largely phased out due to ozone depletion.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as a formulated refrigerant blend
Mixtures containing CFCs with other substances are classified as chemical preparations in Chapter 38 rather than pure compounds.
If chlorinated only, without fluorine
Compounds perhalogenated solely with chlorine fall under the chlorofluoride-excluded provision earlier in 2903.

Import Tips & Compliance
• Verify compliance with Montreal Protocol and EPA regulations on ozone-depleting substances before import
• Include Safety Data Sheets (SDS) and proper UN hazardous material documentation for transport
• Avoid misclassification as a refrigerant mixture which may fall under Chapter 38
