Chlorodifluoromethane (HCFC-22) Refrigerant Gas
Pure chlorodifluoromethane (HCFC-22) is a hydrochlorofluorocarbon used primarily as a refrigerant in air conditioning and refrigeration systems. It falls under HTS 2903.71.01.00 as a halogenated derivative of acyclic hydrocarbons containing two or more different halogens (chlorine and fluorine). This chemically defined compound is supplied in pressurized cylinders for industrial and commercial applications.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If blended with lubricants or oils for direct system charging
Blends with additives for specific refrigeration use fall under prepared chemical preparations rather than pure compounds.
If liquefied and imported primarily as a propellant without refrigeration labeling
Liquefied gases under Chapter 27 if not specifically identified as halogenated derivatives for chemical use.

Import Tips & Compliance
• Verify compliance with Montreal Protocol and EPA phaseout schedules; HCFC-22 imports are restricted post-2020 for non-refill uses
• Include Safety Data Sheets (SDS) and cylinder certifications; ensure DOT-compliant packaging for hazardous material transport
• Avoid misclassification as mixtures; pure HCFC-22 must meet 99%+ purity without additives exceeding chapter note limits
