U.S. imports of halogenated derivatives of acyclic hydrocarbons containing two or more different halogens (SITC 51138) totaled $7.8M in April 2026, traded with 11 countries.
Importers of Halogenated Derivatives of Acyclic Hydrocarbons Containing Two or More Different Halogens paid $680K in duties in April 2026 — an effective duty rate of 9.3% on $7.3M in dutiable value, based on actual customs collections rather than the published tariff schedule. Halogenated Derivatives of Acyclic Hydrocarbons Containing Two or More Different Halogens imports of $7.8M in April 2026 ran 11% below the year-to-date monthly average of $8.7M.
Last updated: April 2026 dataMixed-halogen acyclic derivatives — compounds bearing two or more distinct halogen elements such as chlorine and fluorine on the same carbon chain — include the commercially significant hydrochlorofluorocarbon (HCFC) and hydrofluorocarbon (HFC) refrigerant families, as well as halons used in fire suppression. The presence of multiple halogens typically places these substances under both EPA ozone-depleting substance controls and, for HFCs, the AIM Act phasedown framework, creating a layered compliance environment. Importers must carefully distinguish the specific halogen combination and chain length to determine which regulatory regime and allowance system applies.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Compounds with a single halogen type (e.g., only chlorine or only fluorine) are classified under separate SITC headings, while those bearing two or more different halogens fall here. The distinction is commercially significant because HCFCs (chlorine + fluorine) and HFCs (fluorine only) carry different phasedown schedules and allowance requirements under EPA regulations.
Yes. Halons are Class I ozone-depleting substances under the Clean Air Act. New production is banned, and imports of virgin halons are generally prohibited except under narrow exemptions. Recovered and recycled halons may be imported with EPA authorization. Importers should consult EPA's Stratospheric Protection Division and a licensed customs broker before attempting to import any halon.
