8539 1000
Overview
This HTS category, 8539, encompasses a wide array of electrical lamps and light sources, specifically focusing on filament lamps, discharge lamps, and the increasingly prevalent light-emitting diode (LED) light sources. It also includes specialized units like sealed beam lamp units and ultraviolet or infrared lamps, along with arc lamps. Crucially, this heading extends to cover the essential parts for all these lighting devices. The scope is defined by the fundamental function of generating light through electrical means, distinguishing it from categories covering other electrical equipment or non-electrical lighting solutions.
When classifying items within this heading, it's important to differentiate from sibling categories that fall under Chapter 85 but pertain to different types of electrical apparatus. For instance, while this heading covers the light-generating components, other headings within Section XVI and Chapter 85 would address items such as electrical lighting fixtures (luminaires) or parts of general electrical machinery not specifically related to lamp production. The defining characteristic here is the lamp unit itself or its direct components.
The subcategories within 8539 allow for a more granular classification based on the specific technology and design of the light source. Items are typically divided into sealed beam lamp units, various types of filament lamps (distinguishing between those emitting visible light and those for ultraviolet or infrared purposes), discharge lamps, and LED light sources. This breakdown facilitates precise tariff application by recognizing the distinct technical attributes and applications of each lighting technology. Finally, a dedicated subcategory exists for parts, ensuring that components integral to the function of any lamp within this heading are correctly accounted for.
