HS code for Halon-1211: 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-1211 under HS 2903.76
Halon-1211, chemically known as bromochlorodifluoromethane, is classified under HS code 2903.76. Chapter 29 of the Harmonized System covers organic chemicals, and heading 2903 specifically addresses halogenated derivatives of acyclic hydrocarbons. Within this heading, the 2903.70 series covers derivatives containing two or more different halogens. Subheading 2903.76 is a specific provision for Halon-1211, Halon-1301, and Halon-2402. To be classified here, the product must be a separate chemically defined compound, whether or not containing impurities, as per Note 1 to Chapter 29. Halon-1211 is a colorless gas used primarily in portable fire extinguishers because it is effective on electrical fires and leaves no residue. The classification is determined by GRI 1, which relies on the specific text of the subheading. Because Halon-1211 is a controlled substance under the Montreal Protocol, its classification under 2903.76 is strictly enforced to ensure that trade volumes are reported accurately to environmental authorities. If the substance is mixed with other chemicals or presented as a prepared charge for a fire extinguisher, the classification would shift to Chapter 38, but the pure chemical remains in Chapter 29.

Codes often confused with 2903.76
Common mistake. Halon-1211 is frequently misclassified under 3827.20, which is reserved for mixtures containing Halons. If the product is 98% pure or higher and not blended with other active agents, it belongs in 2903.76. It is also sometimes incorrectly placed in 2903.71 (chlorodifluoromethane) due to the similarity in chemical names, but the presence of bromine requires the use of 2903.76.
Top exporters and importers of HS 290376 (the code used for halon-1211), 2025
In 2025, the largest exporter of HS 290376 (the code used for halon-1211) 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).
