2827.39.90 - Other

This HTS category, 2827.39.90, "Other," encompasses a broad range of inorganic chloride compounds that are not specifically enumerated in preceding subheadings within the "Other chlorides" group. These substances are characterized by their chemical structure, primarily containing the chloride ion (Cl⁻) bonded to various metallic or non-metallic elements, and do not fall under more specific classifications for chlorides of particular elements like vanadium, tin, titanium, tungsten, or barium, which are listed as sibling categories.

The critical distinction for classifying goods under 2827.39.90 lies in the absence of a more precise classification elsewhere in the 2827.39 series. While sibling categories address chlorides of specific metals, this heading serves as a residual category for all other unassigned chloride compounds. For example, chlorides of elements such as calcium, magnesium, or sodium, if not falling under more granular headings within the chlorides chapter, would be considered within the scope of "Other chlorides" and potentially this specific subheading if not otherwise specified.

The subcategories under 2827.39.90 provide further refinement for specific types of "other" chlorides. The subheading 2827.39.90.10 is dedicated to chlorides of lithium, a common alkali metal, which often has distinct industrial applications. The remaining "Other" subheading, 2827.39.90.50, acts as a further residual category for any remaining chloride compounds that do not fit the more specific sub-subheadings within this chapter, ensuring a comprehensive classification system.
