HS Code for HFC-245fa

HFC-245fa, or 1,1,1,3,3-pentafluoropropane, is classified under HS code 2903.47. As a pure, saturated fluorinated derivative of an acyclic hydrocarbon, it is categorized within Chapter 29 (Organic Chemicals). Heading 2903 covers halogenated derivatives of hydrocarbons. The specific subheading 2903.47 was created in the 2022 HS nomenclature to group pentafluoropropanes, including HFC-245fa and its isomer HFC-245ca. The classification is determined by the molecular structure, which consists of a three-carbon propane chain with five fluorine atoms replacing hydrogen atoms. HFC-245fa is widely used as a blowing agent in the production of polyurethane foam and as a specialty solvent. Accurate classification under 2903.47 is essential for tracking the trade of this substance under the Kigali Amendment, as it has a significant global warming potential despite having zero ozone depletion potential.

Products Included

• 1,1,1,3,3-Pentafluoropropane (HFC-245fa)
• 1,1,2,2,3-Pentafluoropropane (HFC-245ca)
• Pure HFC-245fa blowing agent

Common Misclassification

HFC-245fa is often misclassified under HS code 3824.99 or 3827.69. This typically happens when the chemical is imported as part of a pre-blended polyol system for foam production. If the HFC-245fa is mixed with polyols or other additives, it must be classified in Chapter 38. Another error is using 2903.46, which is reserved for hepta- and hexafluoropropanes.

FAQ

What is the HS code for HFC-245fa?

The HS code for pure HFC-245fa is 2903.47.

Is HFC-245fa classified differently if used as a blowing agent?

If it is the pure chemical, it remains 2903.47. However, if it is pre-mixed into a foam-blowing 'system' with other chemicals, it is classified under Chapter 38.
