HS code · 6-digit subheading
HS Code 2903.48 – Saturated fluorinated derivatives of acyclic hydrocarbons; 1,1,1,3,3-pentafluorobutane (HFC-365mfc) and 1,1,1,2,2,3,4,5,5,5-decafluoropentane (HFC-43-10mee)
HS code 2903.48 is the 6-digit subheading for saturated fluorinated derivatives of acyclic hydrocarbons, 1,1,1,3,3-pentafluorobutane (HFC-365mfc) and 1,1,1,2,2,3,4,5,5,5-decafluoropentane (HFC-43-10mee). It is used for HFC-365mfc blowing agent, HFC-43-10mee precision solvent, electronics cleaning fluid, heat transfer fluid and specialty foam agent.
What HS 2903.48 covers
This category includes specialized saturated fluorinated derivatives such as 1,1,1,3,3-pentafluorobutane (HFC-365mfc) and 1,1,1,2,2,3,4,5,5,5-decafluoropentane (HFC-43-10mee). These HFCs are primarily employed as precision cleaning solvents, blowing agents for specialized foams, and heat transfer fluids in niche industrial applications. HFC-43-10mee, in particular, is valued for its low surface tension and non-flammability, making it ideal for cleaning sensitive electronics and as a carrier fluid in various processes. International trade is driven by high-tech manufacturing, electronics industries, and specialized chemical sectors. Exporters are typically chemical companies with advanced synthesis capabilities, while importers are countries with significant electronics production, aerospace industries, or specialized industrial processes. These HFCs, while offering specific performance advantages, are also subject to environmental scrutiny due to their GWP, leading to a continuous push for 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).
