HS Code for HFC-152a

HFC-152a, chemically known as 1,1-difluoroethane, is classified under HS code 2903.43. This classification is governed by the 2022 updates to the Harmonized System, which created specific subheadings for hydrofluorocarbons (HFCs) to support the implementation of the Kigali Amendment. Heading 2903 covers halogenated derivatives of acyclic hydrocarbons, and subheading 2903.43 is the designated category for fluoromethane (HFC-41), 1,2-difluoroethane (HFC-152), and 1,1-difluoroethane (HFC-152a). The classification is based on the chemical's identity as a saturated derivative, meaning it contains only single carbon-carbon bonds. HFC-152a is widely used as an aerosol propellant in consumer products like hairsprays and duster sprays, as well as a foam-blowing agent and a component in refrigerant blends. As a pure, single chemically defined compound, it is classified in Chapter 29 according to Note 1 to that chapter. Proper classification under 2903.43 is essential for international trade, as it allows customs authorities to monitor the volume of this substance and ensure compliance with environmental quotas and licensing requirements. The code ensures that the specific global warming potential (GWP) of HFC-152a is accounted for in national environmental registries.

Products Included

• 1,1-difluoroethane (HFC-152a)
• Fluoromethane (HFC-41)
• 1,2-difluoroethane (HFC-152)
• Pure HFC-152a used as an aerosol propellant
• Pure HFC-152a used as a foam-blowing agent

Common Misclassification

HFC-152a is frequently misclassified under HS code 2903.49, which serves as the residual category for other saturated fluorinated derivatives. Since HFC-152a is specifically named in the subheading for 2903.43, the use of 2903.49 is incorrect. Another common error occurs when HFC-152a is imported in aerosol cans; if the product is a finished consumer good (like a hairspray), it may be classified under Chapter 33, but the bulk chemical itself remains 2903.43. It is also often confused with 3824.78 when it is part of a refrigerant mixture.

FAQ

What is the HS code for HFC-152a?
