8539.21.40.80 - Of a power 500 W or more

This HTS category, 8539.21.40.80, specifically covers tungsten halogen filament lamps that have a power output of 500 watts or more. These are specialized lighting elements designed for high-intensity illumination applications where significant power consumption is required. The classification is rooted within the broader scope of electrical filament and discharge lamps, encompassing a wide range of lighting technologies.

The crucial differentiator for this category lies in its power rating. It is distinguished from its sibling category, 8539.21.40.40, which covers tungsten halogen lamps of a power less than 500 watts. Therefore, when classifying a tungsten halogen lamp, the determining factor at this level is whether its specified power output meets or exceeds the 500-watt threshold.

As this category is a leaf node in the HTS structure, there are no further subcategories. Classification at this level is definitive based on the product's type (tungsten halogen filament lamp) and its power output (500 W or more). Examples within this classification might include high-power projection lamps, industrial lighting components, or specialized automotive headlamps designed for intense illumination and operating at or above this power level.
