8539.52.00 - Light-emitting diode (LED) lamps

This HTS category, 8539.52.00, specifically covers light-emitting diode (LED) lamps. These are complete lighting units designed to produce illumination using semiconductor light-emitting diodes. Unlike LED modules (8539.51.00.00), which are typically components or subassemblies of LED lighting systems, LED lamps are finished products ready for direct use as light sources in various applications.

The distinction between LED lamps and LED modules is crucial for accurate classification. LED modules are generally considered unfinished or intermediate products that require further integration into a larger lighting fixture or system to function as a complete lamp. LED lamps, conversely, are self-contained and provide light directly when powered, often incorporating drivers, optics, and housings within the unit.

Within this category, further subdivisions exist to address specific types and forms of LED lamps. The subcategories based on statistical notes (8539.52.00.10 through 8539.52.00.40) are likely used for statistical tracking and may relate to specific performance characteristics, power ratings, or intended uses as defined by those notes. Additionally, categories for straight linear tubes or U-shaped tubes (8539.52.00.51) and other general forms (8539.52.00.91) allow for the classification of LED lamps based on their physical design and form factor, ensuring granular detail for trade reporting.
