3827.20.00.00 - Containing bromochlorodifluoromethane (Halon-1211), bromotrifluoromethane (Halon-1301) or dibromotetrafluoroethanes (Halon-2402)

This HTS classification, 3827.20.00.00, specifically covers miscellaneous chemical products that are mixtures containing bromochlorodifluoromethane (commonly known as Halon-1211), bromotrifluoromethane (Halon-1301), or dibromotetrafluoroethanes (Halon-2402). These substances are primarily recognized for their historical use as fire extinguishing agents, particularly in specialized applications where their effectiveness and non-conductive properties were critical. The key characteristic for classification under this heading is the presence of one or more of these specific halon compounds as a component within the mixture.

It is important to distinguish this category from other mixtures of halogenated derivatives of methane, ethane, or propane. For instance, sibling categories cover mixtures containing chlorofluorocarbons (CFCs) or hydrochlorofluorocarbons (HCFCs), which have different chemical compositions and regulatory statuses. This heading is distinct from those that contain methyl bromide or bromochloromethane (3827.40.00.00), or those solely comprising trifluoromethane, perfluorocarbons, or other hydrofluorocarbons without the specified halons. The presence of Halon-1211, Halon-1301, or Halon-2402 is the definitive criterion for inclusion here.

As this classification represents a leaf node, there are no further subcategories. Therefore, classification at this level is final. When encountering a mixture, customs professionals should verify the presence of any of the enumerated halon compounds. Mixtures solely containing other halogenated hydrocarbons, or those where the specified halons are present in trace amounts below a de minimis threshold that does not contribute to the primary function of the mixture, would be classified elsewhere.
