9405.99 - Other:

This HTS category, 9405.99, encompasses parts for luminaires and lighting fittings, as well as illuminated signs and nameplates, that are not elsewhere specified or included, and are not made of glass or plastic. This broad classification serves as a residual category for components whose primary material composition does not align with the more specific sibling categories. Examples of items that might fall under this heading include metal mounting brackets, wiring components not integrated into a plastic insulation, or decorative elements made from materials like wood, ceramic, or metal, provided they are intended for use with lighting fixtures or illuminated displays.

Unlike its sibling categories, 9405.91 (Of glass) and 9405.92.00.00 (Of plastics), this heading specifically excludes parts predominantly manufactured from glass or plastic. The key differentiator lies in the material composition of the part. Therefore, a metal lamp shade frame would be classified here, while a glass diffuser would fall under 9405.91, and a plastic lamp base would be classified under 9405.92.00.00. The intent and function as a component for lighting or illuminated signs remain consistent across these related categories.

This category further subdivides to provide more granular classification based on material. The subcategory 9405.99.20.00 specifically addresses parts made of brass, recognizing its common use in lighting fixture components. All other parts not made of glass, plastic, or brass, but still intended for luminaires, lighting fittings, or illuminated signs, are directed to the residual subcategory 9405.99.40 ("Other"). This hierarchical structure ensures precise classification based on both material and intended use.
