HS code for Halon-1301: 2903.76
Halogenated derivatives of acyclic hydrocarbons containing two or more different halogens, bromochlorodifluoromethane (Halon-1211), bromotrifluoromethane (Halon-1301), and dibromotetrafluoroethanes (Halon-2402).
Classification of halon-1301 under HS 2903.76
Halon-1301, chemically known as bromotrifluoromethane, is classified under HS code 2903.76. This classification falls under Chapter 29, which covers organic chemicals. Heading 2903 is dedicated to halogenated derivatives of hydrocarbons. Subheading 2903.76 specifically lists bromochlorodifluoromethane (Halon-1211), bromotrifluoromethane (Halon-1301), and dibromotetrafluoroethanes (Halon-2402). The classification is strictly based on the chemical identity of the substance as a pure halogenated derivative of an acyclic hydrocarbon. As an ozone-depleting substance regulated by the Montreal Protocol, its classification is highly specific to facilitate international monitoring and control of trade. The substance is primarily used as a fire suppressant in specialized environments like data centers and aircraft. For the product to remain in this code, it must be a chemically defined compound. If it is mixed with other chemicals or prepared as a specific fire-extinguishing charge, the classification may shift to a different chapter.

Codes often confused with 2903.76
Common mistake. Halon-1301 is often confused with HS code 3813.00, which covers preparations and charges for fire-extinguishers. If the Halon-1301 is mixed with other agents or is packaged specifically as a ready-to-use fire-extinguishing charge, it moves from Chapter 29 to Chapter 38. Furthermore, if the Halon is contained within a mechanical fire extinguisher, the entire apparatus is classified under 8424.10. Another potential error is 2903.79, which is a residual category for other halogenated derivatives, but since Halon-1301 is explicitly named in 2903.76, that code must be used.
Top exporters and importers of HS 290376 (the code used for halon-1301), 2025
In 2025, the largest exporter of HS 290376 (the code used for halon-1301) 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).
