HS Code for HFC-23

HFC-23, chemically known as trifluoromethane, is classified under HS code 2903.41. This classification is part of Chapter 29, which deals with organic chemicals, specifically the halogenated derivatives of hydrocarbons. Within heading 2903, the subheadings are organized by the type of halogen and the degree of saturation. Subheading 2903.41 is a specific provision for trifluoromethane. This classification is strictly for the chemically defined pure compound. If the HFC-23 is part of a mixture, such as a blended refrigerant used in ultra-low temperature cooling, the classification would shift to Chapter 38. The precision of this code is essential for monitoring environmental regulations and quotas associated with high global warming potential (GWP) gases. Customs authorities use this specific code to track the movement of HFC-23, which is often a byproduct of HCFC-22 production and is subject to strict controls under the Kigali Amendment to the Montreal Protocol.

Products Included

• Pure Trifluoromethane (HFC-23)
• Fluoroform gas
• R-23 refrigerant (pure form)
• Methyl trifluoride
• HFC-23 used as a fire suppressant

Common Misclassification

HFC-23 is often misclassified under 2903.42 (difluoromethane) or 2903.49 (other fluorinated derivatives). It is also frequently confused with HS code 3824.78, which covers mixtures containing perfluorocarbons (PFCs) or hydrofluorocarbons (HFCs). If the product is a blend like R-404A or R-410A, it cannot be classified in Chapter 29 and must be placed in Chapter 38.

FAQ

What is the HS code for HFC-23?

The HS code for pure HFC-23 (trifluoromethane) is 2903.41.

Is HFC-23 regulated for import/export?

Yes, because it is a potent greenhouse gas, HFC-23 classified under 2903.41 often requires specific environmental permits and is subject to phase-down schedules in many countries.
