3824.99.39 - Other

This category, HTS 3824.99.39, encompasses "Other" chemical products and preparations within the broader classification of miscellaneous chemical products not elsewhere specified or included. It serves as a residual category for mixtures of two or more inorganic compounds that do not fit into more specific subheadings within the 3824.99.30 range. This includes inorganic mixtures that are not explicitly covered by sibling categories, such as those of bismuth, hydrosulfite compounds, mercury, molybdenum, or tungsten.

The scope of 3824.99.39 is for those inorganic compound mixtures that lack a more precise tariff designation. Classification here relies on the specific composition and intended use of the mixture, ensuring that it is genuinely not elsewhere specified. If a particular inorganic mixture has a defined application or composition that is recognized in another HTS subheading, it would be classified there rather than under this general "other" designation.

Within this category, two subcategories exist to further refine the classification. HTS 3824.99.39.10 specifically addresses mixtures of lithium nickel cobalt manganese oxides, which are relevant in advanced material applications such as battery technology. The remaining mixtures of inorganic compounds are then directed to HTS 3824.99.39.90, labeled as "Other," providing a final catch-all for unclassified inorganic mixtures.
