HS Code for R-22 refrigerant

R-22 refrigerant, or chlorodifluoromethane (HCFC-22), is classified under HS code 2903.71. This classification falls under the halogenated derivatives of acyclic hydrocarbons containing two or more different halogens. As a hydrochlorofluorocarbon (HCFC), R-22 is a separate chemically defined compound, which places it in Chapter 29 (Organic Chemicals) rather than Chapter 38 (Chemical Products). The specific heading 2903.71 is reserved for chlorodifluoromethane. This gas has been widely used in air conditioning and refrigeration systems, though its trade is heavily restricted in many jurisdictions. The classification is determined by the molecular structure of the gas, which consists of one carbon atom, one hydrogen atom, one chlorine atom, and two fluorine atoms. Accurate classification is essential for compliance with environmental regulations and quota systems governing the phase-out of HCFCs.

Common Misclassification

A common misclassification occurs with HS code 3824.74, which covers mixtures containing HCFCs. If R-22 is blended with other refrigerants (like R-407C components), it loses its identity as a pure compound and must be classified in Chapter 38. It is also occasionally confused with 2903.39 (other fluorinated derivatives), but because R-22 contains both chlorine and fluorine, it must stay within the 2903.7x series. Another error is using 2903.72, which is specifically for R-123.

FAQ
