Dichlorodifluoromethane (R-12 Refrigerant) from China
Dichlorodifluoromethane, also known as R-12 or Freon-12, is a perhalogenated acyclic hydrocarbon containing only fluorine and chlorine halogens, classified under HTS 2903.77.0050 as a halogenated derivative of hydrocarbons. It was widely used as a refrigerant in automotive and domestic air conditioning systems before being phased out due to ozone depletion concerns. Now primarily imported for servicing legacy equipment or as a chemical intermediate.

Import Tips
• Verify compliance with Montreal Protocol and EPA regulations on ozone-depleting substances; obtain necessary exemptions or recycling certifications
• Include Safety Data Sheets (SDS) and purity certificates (typically 99.9%+) in documentation to confirm chemical identity
• Avoid misclassification as mixtures; pure dichlorodifluoromethane must meet chapter 29 notes for separate chemically defined compounds
