Last updated: April 2026 dataBromochlorodifluoromethane (Halon-1211), bromotrifluoromethane (Halon-1301), and dibromotetrafluoroethane (Halon-2402) are among the most potent ozone-depleting substances regulated under the Montreal Protocol, and their production has been banned in developed countries since 1994; US imports are therefore restricted almost entirely to recovered or recycled material for critical-use exemptions. All three substances classify under tariff line 2903760100. South Korea and Saudi Arabia are the leading US source countries under this heading, with Colombia, Bahrain, and Taiwan also appearing as suppliers — a geographic spread that reflects the global trade in reclaimed halon stocks.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
No. The US phased out production and import of new halon under the Clean Air Act consistent with the Montreal Protocol. Only recovered, recycled, or reclaimed halon may be imported, and only for approved critical uses such as aviation and military fire suppression systems. EPA allowances and documentation of the material's reclaimed status are required.
Importers typically need to provide a certificate of reclamation or recycling from the foreign supplier, EPA allowance documentation, and in some cases laboratory analysis confirming the product meets reclaimed-halon purity standards. Customs brokers experienced in ozone-depleting substance entries can advise on the specific filing requirements at the port of entry.
