2903.79.90.70 - Other

This HTS subheading, 2903.79.90.70, encompasses halogenated derivatives of acyclic hydrocarbons that contain at least two different halogens, excluding those specifically enumerated in preceding subheadings. The classification here is for "Other" compounds, meaning it serves as a residual category for such chemicals that do not fit into more specific classifications within the 2903.79 group. These substances are characterized by their acyclic (open-chain) structure and the presence of multiple types of halogen atoms (e.g., chlorine and fluorine, or bromine and chlorine) attached to the hydrocarbon backbone.

This category is distinct from its sibling, 2903.79.90.30, which specifically covers Monochlorotetrafluoroethane (HCFC-124). While both fall under halogenated derivatives of acyclic hydrocarbons containing two or more different halogens, 2903.79.90.70 is intended for all other compounds meeting these criteria that are not HCFC-124. Therefore, its scope is broader and less defined, capturing a variety of complex halogenated organic compounds.

As a leaf node, 2903.79.90.70 has no further subdivisions. Classification within this heading relies on the specific chemical composition and the presence of at least two distinct halogen elements within an acyclic hydrocarbon structure, provided the compound is not otherwise specifically classified. Customs officers will examine the chemical identity and purity to ensure it does not meet the criteria for a more specific HTS code, particularly within Chapter 29 which details organic chemicals.
