HS Code for R-123 refrigerant

R-123 refrigerant, chemically known as dichlorotrifluoroethane (HCFC-123), is classified under HS code 2903.72. This classification is part of the halogenated derivatives of acyclic hydrocarbons. Under the Harmonized System, Chapter 29 covers organic chemicals, and heading 2903 specifically addresses halogenated derivatives. The subcategory 2903.72 is designated for dichlorotrifluoroethanes. This classification is precise because R-123 is a single, chemically defined compound. It is used primarily as a refrigerant in centrifugal chillers and as a blowing agent. Because it contains chlorine, fluorine, and hydrogen, it is categorized as a hydrochlorofluorocarbon (HCFC). The classification is strictly regulated due to environmental protocols, and the HS code ensures that customs authorities can monitor the trade of ozone-depleting substances as required by the Montreal Protocol.

Products Included

• Pure R-123 (Dichlorotrifluoroethane)

• R-123 pressurized in cylinders for industrial cooling

Common Misclassification

R-123 is often misclassified under 3824.74, which is the code for mixtures containing hydrochlorofluorocarbons (HCFCs). If the refrigerant is a blend of different gases rather than pure R-123, it must be moved to Chapter 38. It is also sometimes confused with 2903.71 (R-22), but 2903.72 is specific to the chemical structure of dichlorotrifluoroethane. Importers must ensure the chemical purity exceeds 95% to remain in Chapter 29; otherwise, it may be viewed as a chemical preparation.

FAQ

What is the HS code for R-123 refrigerant?

The HS code for pure R-123 refrigerant (dichlorotrifluoroethane) is 2903.72.

Can R-123 be classified in Chapter 38?

Only if it is part of a mixture or blend; pure R-123 is a chemically defined compound in Chapter 29.
