3827.39.00.00 - Other

HTS code 3827.39.00.00 encompasses miscellaneous chemical products that are mixtures containing halogenated derivatives of methane, ethane, or propane. Specifically, this category applies to mixtures that contain hydrochlorofluorocarbons (HCFCs), which may also include perfluorocarbons (PFCs) or hydrofluorocarbons (HFCs), but crucially, they must not contain chlorofluorocarbons (CFCs). This "Other" designation signifies that these mixtures do not fall under more specific subheadings within the broader category of mixtures containing HCFCs.

This subheading distinguishes itself from its siblings by its residual nature. HTS 3827.31.00.00 specifically covers mixtures containing HCFCs that also include substances falling under HTS subheadings 2903.41 to 2903.48. Similarly, HTS 3827.32.00.00 is designated for other mixtures containing HCFCs, provided they include substances from HTS subheadings 2903.71 to 2903.75. Therefore, 3827.39.00.00 serves as a catch-all for HCFC-containing mixtures that do not meet the specific criteria of these other subheadings but still adhere to the general rule of not containing CFCs.

As a leaf node, this classification does not have further subcategories. Classification under this subheading is determined by the absence of CFCs and the presence of HCFCs, along with the absence of specific halogenated hydrocarbons detailed in its sibling categories. Examples could include certain refrigerant blends or industrial cleaning agents where the precise composition, excluding CFCs, places them outside the more narrowly defined categories.
