HS code for HFC-227ea: 2903.46
Saturated fluorinated derivatives of acyclic hydrocarbons, 1,1,1,2,3,3,3-heptafluoropropane (HFC-227ea), 1,1,1,2,2,3-hexafluoropropane (HFC-236cb), 1,1,1,2,3,3-hexafluoropropane (HFC-236ea) and 1,1,1,3,3,3-hexafluoropropane (HFC-236fa).
Classification of HFC-227ea under HS 2903.46
HFC-227ea, chemically identified as 1,1,1,2,3,3,3-heptafluoropropane, is classified under HS code 2903.46. As a separate chemically defined organic compound, it is situated in Chapter 29. Heading 2903 encompasses halogenated derivatives of hydrocarbons. The specific subheading 2903.46 was established in the 2022 HS nomenclature to group heptafluoropropanes and hexafluoropropanes. HFC-227ea is a saturated fluorinated derivative of propane (an acyclic hydrocarbon). The classification is determined by the propane backbone (three carbon atoms) and the presence of seven fluorine atoms replacing hydrogen. This substance is commonly used in fire suppression systems and as a medical propellant. For the pure chemical, 2903.46 is the mandatory code, ensuring compliance with international trade regulations and environmental monitoring requirements for high global warming potential gases.

Codes often confused with 2903.46
Common mistake. HFC-227ea is often misclassified under HS code 3813.00, which covers preparations and charges for fire-extinguishers. While HFC-227ea is a fire extinguishing agent, the pure chemical remains in Chapter 29. Only when it is part of a mixture or a charged extinguisher does it move to Chapter 38. It is also sometimes confused with 2903.47 (pentafluoropropanes).
Top exporters and importers of HS 290346 (the code used for HFC-227ea), 2025
In 2025, the largest exporter of HS 290346 (the code used for HFC-227ea) in UN Comtrade data was Germany, with 36% of world exports; the largest importer in UN Comtrade data was France, with 29% 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).
