3827.68.00.00 - Other, not included in the subheadings above, containing substances of subheadings 2903.41 to 2903.48 🖩

This HTS classification, 3827.68.00.00, covers miscellaneous chemical mixtures specifically containing halogenated derivatives of methane, ethane, or propane, but only if these mixtures are not provided for in other more specific subheadings within 3827.6. The defining characteristic of this category is that it encompasses mixtures containing substances classified under subheadings 2903.41 to 2903.48, which primarily relate to hydrofluorocarbons (HFCs) and other fluorinated acyclic hydrocarbons. These are chemical products that do not fall into any of the preceding, more precisely defined HFC subheadings within the 3827.6 group.

The distinction of 3827.68.00.00 lies in its residual nature, serving as a catch-all for HFC-containing mixtures that do not meet the specific percentage or compositional criteria of its sibling categories. For instance, siblings 3827.61.00.00 and 3827.64.00.00 are delineated by the presence of specific HFCs like 1,1,1-trifluoroethane (HFC-143a) or 1,1,1,2-tetrafluoroethane (HFC-134a) at specified minimum concentrations, while also excluding unsaturated fluorinated derivatives. Similarly, other siblings focus on particular HFC combinations or percentages, such as those involving pentafluoroethane (HFC-125) or difluoromethane (HFC-32). This category, 3827.68.00.00, applies when the mixture's composition does not align with these explicit requirements, yet it still contains HFCs falling within the broader scope of 2903.41 to 2903.48.

As this subheading is a leaf node, there are no further subdivisions. Therefore, the focus for classification under 3827.68.00.00 is on verifying that the mixture contains HFCs derived from methane, ethane, or propane, and that it is not explicitly covered by any of the preceding, more specific subheadings within 3827.6. This often involves analyzing the complete composition of the mixture to ensure it does not meet the criteria for inclusion in subheadings like 3827.61.00.00 through 3827.65.00.00.
