3827 - Mixtures containing halogenated derivatives of methane, ethane or propane, not elsewhere specified or included:

HTS Code 3827 encompasses a broad range of chemical mixtures specifically formulated with halogenated derivatives of methane, ethane, or propane. These products are not classified under any other more specific chapter or heading within the Harmonized Tariff Schedule. The defining characteristic is the presence of at least one halogenated hydrocarbon derived from these basic alkane structures. This category serves as a residual for such mixtures when they don't fit into more specialized classifications, often related to refrigerants, solvents, or propellants.

Unlike the sibling categories in Chapter 01, which deal with live animals, HTS 3827 falls within Section VI, pertaining to chemical products. Its context is further refined by Chapter 38, which addresses miscellaneous chemical products. Therefore, the primary distinction from siblings lies in its fundamental nature as a chemical mixture rather than a live organism.

Within HTS 3827, subcategories exist to further delineate the specific types of halogenated derivatives present. These subdivisions are crucial for accurate tariff assessment, particularly given the environmental regulations that often apply to halogenated hydrocarbons. For instance, there are distinct classifications for mixtures containing chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs), as well as those containing hydrobromofluorocarbons (HBFCs), carbon tetrachloride, or 1,1,1-trichloroethane. Further breakdowns address mixtures containing specific halons like bromochlorodifluoromethane (Halon-1211) or bromotrifluoromethane (Halon-1301). The subsequent categories distinguish between mixtures containing HCFCs without CFCs, and those containing methyl bromide or bromochloromethane. Finally, separate provisions are made for mixtures containing specific hydrofluorocarbons (HFCs) or perfluorocarbons (PFCs) in the absence of CFCs or HCFCs, as well as an "Other" category for remaining mixtures that fit the general description but not the more specific subdivisions.
