8539.52.00.51 - Straight linear tubes or U-shaped tubes

This HTS category, 8539.52.00.51, specifically encompasses light-emitting diode (LED) light sources that are designed in a straight linear or U-shaped configuration. These are distinct from other forms of LED light sources and are often intended for applications where specific lighting geometries are required, such as in linear fixtures, cove lighting, or specialized industrial equipment. The classification hinges on the physical form factor of the LED light source itself.

While the broader heading 8539.52 covers all LED light sources, this subcategory differentiates itself by the distinct physical shape of the light-emitting element. Its sibling categories, such as 8539.52.00.10 through 8539.52.00.40, are defined by reference to statistical notes that likely pertain to specific technical characteristics, applications, or perhaps internal construction details not immediately apparent from the physical form. Category 8539.52.00.91 represents any other LED light sources that do not fit the straight linear or U-shaped description or the criteria outlined in the preceding statistical notes.

As this is a leaf node within the HTS structure, there are no further subcategories that subdivide this specific classification. Therefore, the classification of an item under 8539.52.00.51 will depend on whether it meets the criteria of being an LED light source with a straight linear or U-shaped design, and is not otherwise classified under a more specific sibling category based on statistical notes. Examples could include LED tubes designed to replace traditional fluorescent tubes, or specific U-shaped LED modules used in lighting systems.
