HS Code 2903.41 – Saturated fluorinated derivatives of acyclic hydrocarbons; trifluoromethane (HFC-23)
HS code 2903.41 is the 6-digit subheading for saturated fluorinated derivatives of acyclic hydrocarbons, trifluoromethane (HFC-23). It is used for trifluoromethane, HFC-23, fluoroform, R-23 and methane trifluoride.
What HS 2903.41 covers
Trifluoromethane, also known as HFC-23, is a saturated fluorinated derivative of acyclic hydrocarbons primarily traded for its use in specialized refrigeration, as a fire suppressant, and as a chemical intermediate. While it is a hydrofluorocarbon (HFC), it is also a potent greenhouse gas with a very high global warming potential (GWP), leading to significant international efforts to control and reduce its emissions under agreements like the Kigali Amendment to the Montreal Protocol. Trade involves chemical manufacturers, refrigeration and fire suppression system producers, and specialized industrial users. Key things to know include the stringent regulations surrounding its production, use, and destruction, particularly concerning its environmental impact. Importers and exporters must comply with international environmental treaties and national regulations aimed at phasing down HFCs. The market is increasingly focused on responsible management and the development of lower-GWP alternatives.

Codes often confused with 2903.41
Common mistake. This code might be confused with other HFCs like 290342 (difluoromethane) or other fluorinated derivatives, but 290341 specifically covers trifluoromethane (HFC-23).
Top exporters and importers of HS code 290341, 2025
In 2025, the largest exporter of HS code 290341 in UN Comtrade data was China, with 48% of world exports; the largest importer in UN Comtrade data was South Korea, with 39% 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. UN Comtrade records Taiwan as "Other Asia, not elsewhere specified". Saudi Arabia's exports under that code are left out: they are far too large to be trade with Taiwan, so mostly undisclosed partners. 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 290341?
This code might be confused with other HFCs like 290342 (difluoromethane) or other fluorinated derivatives, but 290341 specifically covers trifluoromethane (HFC-23).
Which countries are the top exporters of goods under HS code 290341?
In 2025, the top exporters of HS code 290341 in UN Comtrade data were China ($10M, 48% of world exports), Japan ($4.7M) and the United States ($2.6M). World exports came to about $22M, 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.
