HS code · 6-digit subheading
HS Code 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)
HS code 2903.46 is the 6-digit subheading for 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). It is used for HFC-227ea fire suppressant, clean agent extinguishing systems, specialized refrigerants, medical device propellants and industrial solvents.
What HS 2903.46 covers
This category includes several saturated fluorinated derivatives, most notably 1,1,1,2,3,3,3-heptafluoropropane (HFC-227ea), which is widely recognized as a clean agent fire suppressant. Other compounds like HFC-236fa also find use in fire protection. These specialized HFCs are crucial for protecting sensitive equipment in data centers, telecommunications facilities, military applications, and other critical infrastructure where water or other extinguishing agents would cause damage. International trade is driven by the demand from fire protection system manufacturers and service providers globally. Exporters are typically specialized chemical manufacturers, while importers are countries with significant investments in critical infrastructure. Like other HFCs, these are subject to environmental regulations due to their high GWP, influencing their long-term trade viability and encouraging the development of sustainable alternatives.

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).
