3827.90.90.00 - Other

This HTS classification, 3827.90.90.00, covers mixtures containing halogenated derivatives of methane, ethane, or propane that are not specifically provided for elsewhere within heading 3827. These are products that exhibit halogenated hydrocarbon characteristics but do not fit into more narrowly defined subcategories. The key criterion for inclusion here is that the mixture's primary components are halogenated derivatives of simple hydrocarbons (methane, ethane, or propane), and it is not otherwise classified under a more specific heading or subheading.

This category serves as a residual provision for such mixtures, distinguishing itself from sibling categories that are defined by specific halogenation patterns. For instance, while 3827.90.10.00 specifically addresses mixtures chlorinated but not otherwise halogenated, 3827.90.90.00 would encompass mixtures with other combinations of halogens or containing multiple types of halogenated derivatives where the specific halogenation is not the defining characteristic for classification. It is important to note that this heading pertains to mixtures of these halogenated derivatives, not the individual compounds themselves, which may be classified elsewhere.

As this subheading represents a leaf node within the HTS structure, there are no further subcategories to detail. Therefore, classification within 3827.90.90.00 relies on a thorough analysis of the mixture's composition and the absence of a more specific classification elsewhere in the tariff. This requires careful consideration of all constituent halogenated derivatives of methane, ethane, or propane and ensuring they do not meet the criteria for inclusion in more precisely defined subheadings.
