HS code · 6-digit subheading
HS Code 2903.76 – Halogenated derivatives of acyclic hydrocarbons containing two or more different halogens; bromochlorodifluoromethane (Halon-1211), bromotrifluoromethane (Halon-1301), and dibromotetrafluoroethanes (Halon-2402)
HS code 2903.76 is the 6-digit subheading for halogenated derivatives of acyclic hydrocarbons containing two or more different halogens, bromochlorodifluoromethane (Halon-1211), bromotrifluoromethane (Halon-1301), and dibromotetrafluoroethanes (Halon-2402). It is used for bromochlorodifluoromethane, halon-1211, bromotrifluoromethane, halon-1301 and dibromotetrafluoroethane.
What HS 2903.76 covers
This HS code encompasses specific Halon compounds: bromochlorodifluoromethane (Halon-1211), bromotrifluoromethane (Halon-1301), and dibromotetrafluoroethanes (Halon-2402). These substances are potent ozone-depleting substances (ODS) and powerful greenhouse gases, historically renowned for their exceptional fire suppression capabilities in critical applications such as aircraft, military vehicles, and data centers. Due to their severe environmental impact, their production and consumption have been almost entirely phased out globally under the Montreal Protocol, with only very limited, essential uses (e.g., military, aviation safety) permitted, often relying on recycled or existing stocks. International trade is extremely restricted and heavily regulated. Importers and exporters are specialized fire safety companies, defense contractors, and aviation maintenance organizations operating under strict exemptions.

Codes often confused with 2903.76
Common mistake. Could be confused with other fire suppression agents (e.g., HFCs like FM-200 under 2903.39 or inert gas systems) if not specifically identified as brominated fluorocarbons.
Top exporters and importers of HS code 290376, 2025
In 2025, the largest exporter of HS code 290376 in UN Comtrade data was Singapore, with 23% of world exports; the largest importer in UN Comtrade data was Belgium, with 32% 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 290376?
Could be confused with other fire suppression agents (e.g., HFCs like FM-200 under 2903.39 or inert gas systems) if not specifically identified as brominated fluorocarbons.
Which countries are the top exporters of goods under HS code 290376?
In 2025, the top exporters of HS code 290376 in UN Comtrade data were Singapore ($4.8M, 23% of world exports), Brazil ($3.6M) and Italy ($3.5M). World exports came to about $20M, 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.
