9405.61 - Designed for use solely with light-emitting diode (LED) light sources:

This HTS category, 9405.61, specifically classifies illuminated signs, illuminated nameplates, and similar articles that are designed for use solely with light-emitting diode (LED) light sources. The defining characteristic is the exclusive reliance on LED technology for illumination. This ensures that articles using other forms of lighting, such as incandescent bulbs or fluorescent tubes, would be classified elsewhere.

Within the broader grouping of illuminated signs and nameplates (9405.6), this subcategory distinguishes itself from its sibling, 9405.69 ("Other"). The sibling category encompasses illuminated signs and nameplates that do not exclusively utilize LED technology. Therefore, for an item to fall under 9405.61, its light source must be definitively an LED.

Further classification within 9405.61 is achieved through the breakdown into subcategories based on material composition and specific product type. For example, the subcategory "Of base metal" indicates that items constructed primarily from metals will be further distinguished. The subsequent "Other" subcategory under this "Of base metal" designation signifies a residual classification for illuminated LED signs and nameplates made of base metal that do not fit into more specific material subdivisions.
