8539.22.80 - Other

This HTS category, 8539.22.80, encompasses "Other" filament lamps that are not specifically classified elsewhere within the 8539.22 subheadings. These lamps are characterized by their power output not exceeding 200 watts and a voltage requirement exceeding 100 volts. This classification serves as a residual category for filament lamps meeting these general specifications but lacking the specific attributes of other more narrowly defined subcategories.

Crucially, this category distinguishes itself from the sibling category 8539.22.40.00, which is exclusively reserved for "Christmas-tree lamps." Therefore, any filament lamp meeting the wattage and voltage criteria but not intended for decorative Christmas lighting would fall under this 8539.22.80 classification. The scope here is broad, covering general-purpose filament lighting applications where specific product types are not otherwise designated.

Further refinement within this category is achieved through its subcategories, which differentiate based on power output. Subcategories distinguish between lamps "Of a power not exceeding 150 W" and "Of a power exceeding 150 W" (specifically 8539.22.80.70). This bifurcation allows for a more precise classification based on the wattage specification, which is a key technical characteristic for electrical components like lamps.
