HS code · 6-digit subheading
HS Code 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)
HS code 2903.47 is the 6-digit subheading for saturated fluorinated derivatives of acyclic hydrocarbons, 1,1,1,3,3-pentafluoropropane (HFC-245fa) and 1,1,2,2,3-pentafluoropropane (HFC-245ca). It is used for HFC-245fa foam blowing agent, polyurethane insulation component, organic Rankine cycle fluid, specialty solvent and refrigeration insulation.
What HS 2903.47 covers
This HS code covers specific saturated fluorinated derivatives, primarily 1,1,1,3,3-pentafluoropropane (HFC-245fa) and 1,1,2,2,3-pentafluoropropane (HFC-245ca). HFC-245fa is predominantly used as a blowing agent for rigid polyurethane foams, which are vital for insulation in refrigerators, freezers, and building panels. It also finds applications in organic Rankine cycle systems for waste heat recovery and as a specialty solvent. The international trade involves chemical producers supplying to foam manufacturers and insulation industries worldwide. Importers are typically countries with robust construction sectors and appliance manufacturing capabilities. While HFC-245fa has a lower GWP than some older blowing agents, it is still an HFC and falls under the scope of the Kigali Amendment's phase-down, driving a transition towards even lower-GWP alternatives like hydrofluoroolefins (HFOs) in many regions.

Codes often confused with 2903.47
Common mistake. Often confused with other HFC blowing agents or even older HCFC blowing agents (e.g., HCFC-141b, under 2903.49 or similar), due to their shared function in foam production, requiring precise chemical identification.
Top exporters and importers of HS code 290347, 2025
In 2025, the largest exporter of HS code 290347 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).

What are common misclassifications for HS code 290347?
Often confused with other HFC blowing agents or even older HCFC blowing agents (e.g., HCFC-141b, under 2903.49 or similar), due to their shared function in foam production, requiring precise chemical identification.
Which countries are the top exporters of goods under HS code 290347?
In 2025, the top exporters of HS code 290347 in UN Comtrade data were China ($45M, 85% of world exports), the United States ($6.2M) and the Netherlands ($824K). World exports came to about $53M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
