2903.79 - Other:

This HTS category, 2903.79, encompasses halogenated derivatives of acyclic hydrocarbons that contain two or more different halogens. These compounds are distinct from their sibling categories, which specifically enumerate certain chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) such as chlorodifluoromethane, dichlorotrifluoroethanes, and others. Instead, 2903.79 includes a broader range of compounds where the specific combinations of halogens or their placement on the acyclic hydrocarbon chain do not align with the more narrowly defined sibling codes.

The primary distinguishing feature of goods classified under 2903.79 lies in the presence of multiple, different halogen atoms (e.g., chlorine and bromine, or fluorine and bromine) attached to an acyclic hydrocarbon structure, and a lack of specific enumeration under preceding subheadings. This category serves as a residual for such compounds when they are not otherwise specifically listed, ensuring comprehensive coverage within the broader group of halogenated hydrocarbons.

Within 2903.79, there are two primary subcategories. The first, 2903.79.10.00, specifically identifies bromochloromethane, a compound that fits the general description but warrants individual classification due to its specific nature. The second subcategory, 2903.79.90, is a catch-all for all other compounds meeting the criteria of containing two or more different halogens on an acyclic hydrocarbon backbone, but which are not bromochloromethane or any of the HCFCs enumerated in preceding sibling codes.
