8539.90.00.00 - Parts 🖩

This HTS category, 8539.90.00.00, encompasses "Parts" for electrical filament or discharge lamps, including sealed beam lamp units, ultraviolet or infrared lamps, arc lamps, and light-emitting diode (LED) light sources. It serves as a residual category for components and accessories specifically designed for the items classified under heading 8539 that do not fit into the more specific subheadings. This includes items such as lamp bases, holders, internal filaments, electrodes, drivers, and housings, provided they are identifiable as parts of the lamps described in the parent heading.

It is crucial to distinguish this category from its sibling entries, which cover complete lamp units and specific types of light sources. Unlike 8539.10.00 (Sealed beam lamp units) or the subheadings for filament lamps, discharge lamps, ultraviolet or infrared lamps, and LED light sources, this category is exclusively for individual components and not finished, functional lighting apparatus. If a part can be clearly identified as belonging to a specific type of lamp enumerated elsewhere in 8539, it should be classified accordingly. However, if a part is general in nature or its specific application to a particular lamp type is not readily apparent, it falls here.

As this node represents a "leaf node," meaning it has no further subcategories, the classification focus is on ensuring that items are indeed "parts" of the lamps described in heading 8539 and not, for example, general electrical components or finished goods. Examples of items classified here include lamp bases made of ceramic or metal, internal filament supports, glass envelopes not yet assembled into a complete lamp, or electronic drivers solely intended for LED light sources. The key criterion is whether the item contributes to the function or construction of a lamp classified under 8539.
