Halon production and import for new uses is restricted under the Montreal Protocol and US EPA regulations implementing it. Halon charges may only be imported for certain exempted critical uses (aviation, military) and must comply with EPA's halon management requirements. Importers of any halogenated extinguishing agent should confirm current EPA exemption status before shipment.
