HS code for Halon mixtures: 3827.20
Mixtures containing halogenated derivatives of methane, ethane or propane, not elsewhere specified or included, containing bromochlorodifluoromethane (Halon-1211), bromotrifluoromethane (Halon-1301) or dibromotetrafluoroethanes (Halon-2402).
Classification of halon mixtures under HS 3827.20
Halon mixtures are classified under HS code 3827.20. This code was introduced in recent HS nomenclature updates to better track substances controlled under the Montreal Protocol on Substances that Deplete the Ozone Layer. Heading 3827 covers mixtures containing halogenated derivatives of methane, ethane, or propane. Subheading 3827.20 specifically identifies mixtures containing bromochlorodifluoromethane (Halon-1211), bromotrifluoromethane (Halon-1301), or dibromotetrafluoroethanes (Halon-2402). These substances are primarily used as fire extinguishing agents due to their ability to interrupt the chemical reaction of fire. The classification depends on the product being a mixture; if the substance were a chemically pure compound, it would be classified in Chapter 29. However, most commercial Halon products are blended with stabilizers, propellants, or other agents, placing them in Chapter 38. According to GRI 1 and 6, the specific mention of these Halon types in the subheading text for 3827.20 takes precedence over more general categories. This classification is essential for regulatory bodies to monitor the phase-out and controlled use of these high-ozone-depleting substances in international trade.

Codes often confused with 3827.20
Common mistake. Halon mixtures are often misclassified under 2903.76, which is the code for pure Halon compounds. If the product contains any additives or is a blend of different Halons, it must move to 3827.20. Additionally, they are sometimes confused with heading 3813, which covers prepared fire-extinguisher charges; however, 3827.20 is more specific for the chemical composition of the mixture itself.
Top exporters and importers of HS 382720 (the code used for halon mixtures), 2025
In 2025, the largest exporter of HS 382720 (the code used for halon mixtures) in UN Comtrade data was the United States, with 39% of world exports; the largest importer in UN Comtrade data was Israel, with 45% 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).
