8539.52.00.91 - Other

This HTS classification, 8539.52.00.91, covers "Other" light-emitting diode (LED) lamps that do not fall under the more specific subheadings within the 8539.52.00 category. This designation is typically applied to LED lamps that do not conform to the specific definitions provided in statistical notes 7(a) through 7(d) of Chapter 85, nor are they classified as straight linear or U-shaped tubes under 8539.52.00.51.

The critical factor for classifying an LED lamp under this residual "Other" category is the absence of specific characteristics that would place it into the preceding, more detailed sibling classifications. These preceding categories are distinguished by their adherence to defined statistical note criteria or by their specific physical form factors, such as linear or U-shaped tubes. Therefore, an LED lamp would be classified here if it does not fit the descriptions of those explicitly defined categories.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. The classification of an LED lamp under 8539.52.00.91 hinges on its exclusion from all other more precisely defined LED lamp categories at this level. When classifying, customs professionals must carefully review the specific design, intended use, and adherence to any relevant statistical note definitions to ensure correct placement, resorting to this "Other" classification only after all other options have been exhausted.
