HS Code for HCFC-123

HCFC-123, chemically known as dichlorotrifluoroethane, is classified under HS code 2903.72. As a pure chemical substance, it falls under Chapter 29 (Organic Chemicals). Heading 2903 covers halogenated derivatives of acyclic hydrocarbons. Subheading 2903.72 is the specific international designation for dichlorotrifluoroethanes. This classification is strictly for the pure chemical or commercially pure substance. If HCFC-123 is mixed with other refrigerants or chemicals, the classification shifts to Chapter 38. The precision of this code allows for the monitoring of this specific ozone-depleting substance as it is phased out under international environmental agreements. HCFC-123 is primarily used as a refrigerant in centrifugal chillers and as a specialized fire extinguishing agent. Its classification is determined by its molecular structure, specifically being an ethane derivative where hydrogen atoms have been replaced by both chlorine and fluorine atoms.

Common Misclassification

HCFC-123 is often misclassified under HS code 2903.71, which is specifically for chlorodifluoromethane (HCFC-22). It is also sometimes incorrectly placed in 3827.32 if the importer does not realize the product is a pure substance rather than a mixture. Pure substances must stay in Chapter 29.
