HS Code for HFC-134a

HFC-134a, or 1,1,1,2-tetrafluoroethane, is classified under HS code 2903.45. This classification follows the structure of the Harmonized System where pure organic chemicals are categorized in Chapter 29. Heading 2903 is dedicated to halogenated derivatives of hydrocarbons. Because HFC-134a is a saturated acyclic hydrocarbon derivative containing only fluorine halogens, it falls under the specific sub-group for fluorinated derivatives. The 2022 HS update created subheading 2903.45 specifically for tetrafluoroethanes. This includes both the common HFC-134a and its isomer HFC-134 (1,1,2,2-tetrafluoroethane). The classification is based on the molecular formula C2H2F4. Accurate classification is vital for customs authorities to monitor the import and export of this substance, which is widely used as a refrigerant and propellant but is subject to phase-down schedules due to its global warming potential.

Products Included

• 1,1,1,2-Tetrafluoroethane (HFC-134a)
• 1,1,2,2-Tetrafluoroethane (HFC-134)

Common Misclassification

A common misclassification for HFC-134a is HS code 3827.62. This code is intended for mixtures containing tetrafluoroethanes and pentafluoroethane. Importers often confuse the pure gas with refrigerant blends that contain HFC-134a. Additionally, it is sometimes incorrectly placed under 2903.44, which is the code for pentafluoroethane (HFC-125).

FAQ

What is the HS code for HFC-134a?
