HS code for HFC-245fa: 2903.47
Saturated fluorinated derivatives of acyclic hydrocarbons, 1,1,1,3,3-pentafluoropropane (HFC-245fa) and 1,1,2,2,3-pentafluoropropane (HFC-245ca).
Classification of HFC-245fa under HS 2903.47
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.

Codes often confused with 2903.47
Common mistake. 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.
Top exporters and importers of HS 290347 (the code used for HFC-245fa), 2025
In 2025, the largest exporter of HS 290347 (the code used for HFC-245fa) in UN Comtrade data was China, with 85% of world exports; the largest importer in UN Comtrade data was South Korea, with 66% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).

Questions about HFC-245fa
What is the HS code for HFC-245fa?
The HS code for HFC-245fa is 290347 (Saturated fluorinated derivatives of acyclic hydrocarbons; 1,1,1,3,3-pentafluoropropane (HFC-245fa) and 1,1,2,2,3-pentafluoropropane (HFC-245ca)). The HS code for pure HFC-245fa is 2903.47.
How do I classify HFC-245fa for customs?
HFC-245fa is classified under HS code 290347 — Saturated fluorinated derivatives of acyclic hydrocarbons; 1,1,1,3,3-pentafluoropropane (HFC-245fa) and 1,1,2,2,3-pentafluoropropane (HFC-245ca). This is a 6-digit subheading level code.
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.
Which countries are the top exporters of HFC-245fa (HS 290347)?
In 2025, the top exporters of HS 290347 (the code used for HFC-245fa) in UN Comtrade data were China ($45M, 85% of world exports), the United States ($6.2M) and the Netherlands ($824K). World exports came to about $53M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
