HS code for HFC-245ca: 2903.47
Saturated fluorinated derivatives of acyclic hydrocarbons, 1,1,1,3,3-pentafluoropropane (HFC-245fa) and 1,1,2,2,3-pentafluoropropane (HFC-245ca).
Classification of HFC-245ca under HS 2903.47
HFC-245ca, chemically identified as 1,1,2,2,3-pentafluoropropane, is classified under HS code 2903.47. This classification is determined by the Harmonized System's systematic approach to organic chemicals in Chapter 29. Specifically, heading 2903 covers halogenated derivatives of hydrocarbons. Within this heading, the nomenclature distinguishes between saturated and unsaturated derivatives, as well as the specific type of halogen present. HFC-245ca is a saturated acyclic hydrocarbon where five hydrogen atoms have been replaced by fluorine. Following the 2022 updates to the Harmonized System, subheading 2903.47 was specifically designated to encompass two isomers of pentafluoropropane: HFC-245fa and HFC-245ca. The classification logic relies on the fact that the substance is a separate chemically defined compound, not a mixture, and meets the structural criteria of being a saturated fluorinated derivative of an acyclic hydrocarbon. This specific code allows customs authorities to monitor the trade of these substances, which are often used as blowing agents or refrigerants, in accordance with international environmental agreements like the Montreal Protocol.

Codes often confused with 2903.47
Common mistake. HFC-245ca is frequently misclassified under HS code 2903.49, which is a residual category for "other" saturated fluorinated derivatives. This occurs when the specific listing for pentafluoropropanes in 2903.47 is overlooked. Additionally, it may be confused with HS code 3824.78 if the product is part of a refrigerant blend; however, pure HFC-245ca must remain in Chapter 29. Another common error involves HS code 2903.41, which is strictly for trifluoromethane.
Top exporters and importers of HS 290347 (the code used for HFC-245ca), 2025
In 2025, the largest exporter of HS 290347 (the code used for HFC-245ca) in UN Comtrade data was China, with 85% of world exports; the largest importer in UN Comtrade data was South Korea, with 66% 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).
