2903.76.01.00 - Bromochlorodifluoromethane (Halon-1211), bromotrifluoromethane (Halon-1301) and dibromotetrafluoroethanes (Halon-2402)

This HTS category encompasses specific halogenated hydrocarbons that contain at least two different halogen elements, and are derived from acyclic hydrocarbons. The primary items classified here are bromochlorodifluoromethane, also known as Halon-1211, bromotrifluoromethane, identified as Halon-1301, and dibromotetrafluoroethanes, referred to as Halon-2402. These substances are characterized by their unique combinations of bromine, chlorine, and fluorine atoms bonded to a carbon backbone, distinguishing them from other halogenated hydrocarbons.

The key differentiating factor for this group of compounds lies in their specific elemental composition and the presence of both bromine and chlorine, alongside fluorine. Unlike sibling categories such as chlorodifluoromethane (HCFC-22) or dichlorotrifluoroethanes (HCFC-123), which primarily feature chlorine and fluorine, the Halon compounds classified under 2903.76.01.00 inherently include bromine as a significant halogen component. This distinction is crucial for accurate tariff application and regulatory compliance, as these specific brominated compounds often have unique properties and applications.

As this is a leaf node within the HTS structure, there are no further subdivisions under this code. Therefore, the classification under 2903.76.01.00 is definitive for the listed substances. Import and export activities involving bromochlorodifluoromethane, bromotrifluoromethane, and dibromotetrafluoroethanes will be subject to the specific duties and regulations associated with this precise tariff line, emphasizing the importance of accurate identification of these Halon agents.
