Dichlorodifluoromethane (R-12 Refrigerant)
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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If blended with lubricants or other refrigerants for retail sale
Blends or mixtures of halogenated hydrocarbons fall under chapter 38 as chemical preparations, not pure compounds of chapter 29.
If chlorodifluoromethane (HCFC-22) instead of dichlorodifluoromethane
Different halogen composition changes the specific subheading within halogenated acyclic hydrocarbons.
If for bulk import in liquefied form without chemical purity documentation
Could be treated as petroleum gases if not documented as meeting chapter 29 chemically defined compound criteria.

Import Tips & Compliance
• 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
