8539.10.00.50 - For vehicles of subheading 8701.21, 8701.22, 8701.23, 8701.24 or 8701.29 or heading 8702, 8703, 8704, 8705 or 8711

This HTS category, 8539.10.00.50, specifically classifies sealed beam lamp units designed for use in vehicles. These are integrated lighting units, typically comprising a bulb and reflector enclosed within a sealed glass or plastic housing. The critical defining feature for this classification is the intended application in motor vehicles falling under specific HTS subheadings and headings, including motorcycles (8711) and various categories of cars, trucks, and buses (8701.21-8701.29, 8702, 8703, 8704, 8705). The dimensions specified in the parent category (15.24 cm or over) further refine the scope of these vehicle-specific sealed beam lamp units.

This category is distinguished from its sibling, 8539.10.00.60 ("Other"), by its explicit designation and market for automotive applications. While both fall under sealed beam lamp units with dimensions of 15.24 cm or over, the ".50" code is reserved for those specifically manufactured or marketed for installation in vehicles. The ".60" code would encompass other sealed beam lamp units of the same size that are not intended for this particular vehicular use, such as those for industrial or specialized equipment.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. The classification is complete at this level, meaning that any sealed beam lamp unit measuring 15.24 cm or over and intended for use in the specified vehicle categories will be classified under 8539.10.00.50. Classification decisions should rely on clear documentation regarding the intended end-use, marketing, and design of the lamp unit.
