3827.69.00.00 - Other

This category, HTS 3827.69.00.00, covers mixtures containing halogenated derivatives of methane, ethane, or propane, specifically focusing on those that contain other hydrofluorocarbons (HFCs) but are free of chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs). These are essentially specialized chemical mixtures whose primary distinguishing characteristic is the presence of HFCs, without the inclusion of older, more environmentally harmful refrigerants or blowing agents. The "Other" designation signifies that these mixtures do not meet the specific compositional criteria outlined in the preceding subheadings within the 3827.6x series.

The key differentiator for this subheading lies in what it *excludes*. Unlike its siblings, which are defined by the presence of specific HFCs in particular percentages (e.g., 1,1,1-trifluoroethane in 3827.61, pentafluoroethane in 3827.62 and 3827.63, 1,1,1,2-tetrafluoroethane in 3827.64, or specific combinations like difluoromethane and pentafluoroethane in 3827.65), this category encompasses any HFC-containing mixture that does not fall under those precise definitions. This implies that the composition, while still featuring HFCs and excluding CFCs/HCFCs, does not meet the specified minimum mass percentages or combinations of other HFCs that would qualify it for a more specific subheading.

As a leaf node, HTS 3827.69.00.00 represents the final classification for eligible mixtures. Therefore, the focus for classification within this subheading is on confirming that the mixture contains HFCs, does not contain CFCs or HCFCs, and importantly, does not satisfy the specific compositional criteria of any of the preceding, more detailed HTS subheadings under 3827.6x. Examples might include certain specialized industrial solvents, fire suppression agents, or refrigerant blends that utilize HFCs but do not conform to the precise specifications of more commonly defined or regulated HFC blends.
