8539.22.80.10 - 3-way

This HTS classification covers filament lamps that are not ultraviolet or infrared lamps, specifically those with a power rating not exceeding 150 Watts and designed for use with voltages exceeding 100 Volts. Within this broader category of "Other" filament lamps, this subcategory "3-way" distinguishes itself by referring to lamps designed to operate at multiple illumination levels, typically achieved through different filament configurations or internal switching mechanisms. These lamps are commonly found in applications where variable lighting intensity is desired, such as in certain household lamps or specialized fixtures.

This classification is distinguished from its sibling, "Decorative," which would encompass filament lamps primarily valued for their aesthetic appeal, often featuring intricate designs or specialized glass envelopes, regardless of their power or voltage. The "3-way" designation focuses on a functional aspect of the lamp's operation rather than its ornamental characteristics or a general "standard household" use.

As this node represents a leaf category within the HTS, there are no further subcategories. Classification at this level relies on the precise determination of the lamp's multi-level illumination capability and its adherence to the specified power (not exceeding 150 W) and voltage (exceeding 100 V) parameters.
