9405.31.00 - Designed for use solely with light-emitting diode (LED) light sources

This HTS category, 9405.31.00, specifically covers lighting strings designed for use with Light-Emitting Diode (LED) light sources, intended for applications such as Christmas tree decorations. The defining characteristic is the integrated LED technology, which differentiates these strings from other types of decorative lighting.

This category is distinguished from its sibling, 9405.39.00, by its explicit limitation to LED technology. The "Other" category at the same level would encompass lighting strings that do not exclusively use LED technology, potentially including incandescent or other older lighting methods.

Within this category, further subclassification exists to refine the classification based on specific product configurations. 9405.31.00.10 covers "Miniature series wired sets," which typically implies smaller gauge wiring and a series connection arrangement. The remaining products fall under 9405.31.00.40, providing a broader classification for other LED lighting strings not meeting the criteria for miniature wired sets.
