HS code · 6-digit subheading
HS Code 2903.44 – Saturated fluorinated derivatives of acyclic hydrocarbons; pentafluoroethane (HFC-125), 1,1,1-trifluoroethane (HFC-143a) and 1,1,2-trifluoroethane (HFC-143)
HS code 2903.44 is the 6-digit subheading for saturated fluorinated derivatives of acyclic hydrocarbons, pentafluoroethane (HFC-125), 1,1,1-trifluoroethane (HFC-143a) and 1,1,2-trifluoroethane (HFC-143). It is used for HFC-125 refrigerant, HFC-143a refrigerant, R-410A blend component, R-404A blend component and fire suppression agents.
What HS 2903.44 covers
This category encompasses specific saturated fluorinated derivatives, notably pentafluoroethane (HFC-125) and 1,1,1-trifluoroethane (HFC-143a). These HFCs are critical components in many refrigerant blends, such as R-410A and R-404A, which are extensively used in residential and commercial air conditioning, as well as refrigeration systems. Beyond refrigeration, they also serve as fire suppressants in specialized applications. The global trade is dominated by large chemical manufacturers supplying to HVAC-R equipment producers and service providers worldwide. Importers are typically nations with high demand for cooling technologies and industrial safety systems. Due to their high Global Warming Potential (GWP), these HFCs are subject to stringent international regulations, including phase-down schedules under the Kigali Amendment, which significantly impacts trade patterns and accelerates the shift towards lower-GWP alternatives.

Codes often confused with 2903.44
Common mistake. Often confused with other HFCs in 2903.4x, particularly 2903.45 (HFC-134a) or 2903.46 (HFC-227ea), due to their common use in refrigeration and fire suppression, necessitating precise chemical identification.
Top exporters and importers of HS code 290344, 2025
In 2025, the largest exporter of HS code 290344 in UN Comtrade data was China, with 40% of world exports; the largest importer in UN Comtrade data was the United States, with 31% 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 marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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).
