HS code for Halon-2402: 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-2402 under HS 2903.76
Halon-2402, chemically known as 1,2-dibromotetrafluoroethane (C2Br2F4), is classified under HS code 2903.76. This classification is governed by the General Interpretative Rules (GIR) of the Harmonized System, specifically GIR 1, which dictates that classification is determined by the terms of the headings and any relative section or chapter notes. Chapter 29 is dedicated to organic chemicals, and heading 2903 specifically addresses halogenated derivatives of acyclic hydrocarbons. Within this heading, the 2903.7x series focuses on derivatives containing two or more different halogens. Halon-2402 is explicitly named in the description for 2903.76, alongside other ozone-depleting substances like Halon-1211 and Halon-1301. This classification applies to the substance when it is a separate chemically defined compound. If the Halon-2402 is part of a mixture or a prepared charge for a fire extinguisher, it may be classified elsewhere, but in its pure chemical form, 2903.76 is the definitive code. The international community monitors this code closely due to the Montreal Protocol, which restricts the production and trade of such halons to protect the ozone layer.

Codes often confused with 2903.76
Common mistake. A common error is classifying Halon-2402 under HS code 3813.00, which covers "Preparations and charges for fire-extinguishers." While Halon-2402 is used in fire extinguishers, 3813.00 is only for mixtures or products put up in the form of charges. If the substance is pure, it must stay in Chapter 29. Another confusion arises with 2903.71 through 2903.75, which cover other halons like chlorodifluoromethane. Each specific chemical structure has its own designated subheading.
Top exporters and importers of HS 290376 (the code used for halon-2402), 2025
In 2025, the largest exporter of HS 290376 (the code used for halon-2402) 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).

Questions about halon-2402
What is the HS code for Halon-2402?
The HS code for Halon-2402 is 290376 (Halogenated derivatives of acyclic hydrocarbons containing two or more different halogens; bromochlorodifluoromethane (Halon-1211), bromotrifluoromethane (Halon-1301), and dibromotetrafluoroethanes (Halon-2402)). The HS code for Halon-2402 is 2903.76.
How do I classify Halon-2402 for customs?
Halon-2402 is classified under HS code 290376 — Halogenated derivatives of acyclic hydrocarbons containing two or more different halogens; bromochlorodifluoromethane (Halon-1211), bromotrifluoromethane (Halon-1301), and dibromotetrafluoroethanes (Halon-2402). This is a 6-digit subheading level code.
Is Halon-2402 still legal to trade?
Trade is strictly regulated under the Montreal Protocol; it is generally banned for most uses except for "essential uses" like aviation or military applications, and requires specific import/export permits from environmental agencies.
Which countries are the top exporters of halon-2402 (HS 290376)?
In 2025, the top exporters of HS 290376 (the code used for halon-2402) 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).
