HS Code for HFC-125

HFC-125, chemically known as pentafluoroethane, is classified under HS code 2903.44. This classification is determined by the General Rules for the Interpretation (GRI) of the Harmonized System, specifically GRI 1 and GRI 6. As a separate chemically defined organic compound, HFC-125 falls within Chapter 29 (Organic Chemicals). Heading 2903 covers halogenated derivatives of hydrocarbons. Within this heading, the 2022 HS nomenclature updates specifically partitioned fluorinated derivatives into subheadings based on their chemical structure and saturation. Subheading 2903.44 is designated for saturated fluorinated derivatives of acyclic hydrocarbons, specifically naming pentafluoroethane (HFC-125) alongside 1,1,1-trifluoroethane (HFC-143a) and 1,1,2-trifluoroethane (HFC-143). The classification relies on the fact that the molecule consists of an ethane backbone where five hydrogen atoms have been replaced by fluorine atoms, and it contains no other halogens such as chlorine or bromine. This code is essential for tracking substances regulated under the Kigali Amendment to the Montreal Protocol.

Products Included

• Pentafluoroethane (HFC-125)
• 1,1,1-Trifluoroethane (HFC-143a)
• 1,1,2-Trifluoroethane (HFC-143)
• Pure HFC-125 refrigerant gas

Common Misclassification

HFC-125 is frequently misclassified under HS code 3827.61. This occurs because HFC-125 is a primary component of the popular refrigerant blend R-410A. However, while the blend R-410A belongs in Chapter 38 as a mixture, the pure chemical HFC-125 must be classified in Chapter 29. Another common error is using 2903.45, which is reserved for tetrafluoroethanes like HFC-134a.

FAQ

What is the HS code for HFC-125?

The HS code for pure HFC-125 (pentafluoroethane) is 2903.44.

Is HFC-125 classified differently if it is in a mixture?

Yes, if HFC-125 is mixed with other hydrofluorocarbons, such as in R-404A or R-410A, it is classified under heading 3827 rather than 2903.
