8539.51.00.00 - Light-emitting diode (LED) modules

This HTS category, 8539.51.00.00, specifically covers light-emitting diode (LED) modules. These are self-contained units designed to produce light using semiconductor technology. An LED module typically comprises one or more LED chips integrated with necessary electronic components such as resistors, capacitors, and sometimes driver circuitry, mounted on a substrate or printed circuit board. The primary purpose of these modules is to serve as a light source, but they are not usually intended for direct end-user application as a complete lighting fixture without further integration into a larger assembly.

This classification is distinct from its sibling category, 8539.52.00, which covers complete LED lamps. While both utilize LED technology, the key distinction lies in the degree of completion. LED modules are component parts or subassemblies, whereas LED lamps are finished products ready for installation and use in lighting applications (e.g., bulbs, integrated downlights). Therefore, if an LED product is designed to be directly screwed into a socket or otherwise installed as a standalone light source for illumination, it would likely fall under 8539.52.00.

As this is a leaf node within the HTS structure, there are no further subcategories. This means that any product meeting the description of a light-emitting diode (LED) module, irrespective of its specific form factor, size, or intended application within a larger lighting system, will be classified under 8539.51.00.00. Classification decisions within this code will therefore hinge on determining whether the item is an integrated LED light source module rather than a finished LED lamp.
