HS code for HFC-43-10mee: 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).
Classification of HFC-43-10mee under HS 2903.48
HFC-43-10mee, with the chemical name 1,1,1,2,2,3,4,5,5,5-decafluoropentane, is classified under HS code 2903.48. This classification follows the rules of Chapter 29 for organic chemicals. Heading 2903 is reserved for halogenated derivatives of hydrocarbons, and the subheadings are organized by the degree of saturation and the specific halogens involved. HFC-43-10mee is a saturated acyclic hydrocarbon derivative containing only fluorine. The 2022 HS nomenclature updates grouped 1,1,1,3,3-pentafluorobutane (HFC-365mfc) and 1,1,1,2,2,3,4,5,5,5-decafluoropentane (HFC-43-10mee) together under subheading 2903.48. This specific assignment is based on the chemical's molecular complexity and its role as a high-performance cleaning agent and solvent. As a pure, chemically defined compound, it must be classified in Chapter 29. The classification ensures that this specific decafluoropentane is distinguished from other fluorinated alkanes, facilitating accurate environmental reporting and duty assessment. Its use as a carrier fluid and specialized solvent in electronics manufacturing makes its precise classification essential for global supply chain transparency.

Codes often confused with 2903.48
Common mistake. HFC-43-10mee is often misclassified under HS code 2903.49, which serves as the "other" category for saturated fluorinated derivatives. Before the 2022 update, many decafluoropentanes were placed there, but they now belong in 2903.48. It may also be confused with HS code 3814.00 if it is sold as a prepared organic composite solvent, though pure HFC-43-10mee should remain in 2903.48.
Top exporters and importers of HS 290348 (the code used for HFC-43-10mee), 2025
In 2025, the largest exporter of HS 290348 (the code used for HFC-43-10mee) in UN Comtrade data was Japan, with 77% of world exports; the largest importer in UN Comtrade data was the United States, with 65% of world imports. Mexico reports $578M of its heading 2903 imports without product detail (confidential), so it may also belong among the top importers.

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).
