9405.21 - Designed for use solely with light-emitting diode (LED) light sources:

This HTS category, 9405.21, specifically enumerates electric table, desk, bedside, or floor-standing luminaires that are designed for exclusive use with light-emitting diode (LED) light sources. This designation focuses on the integrated lighting technology, ensuring that the luminaire's design and functionality are optimized for LED bulb compatibility. Examples within this category would include LED desk lamps with adjustable arms, LED bedside reading lamps, and LED floor lamps, provided they are intended to house only LED light sources.

This subcategory distinguishes itself from its sibling, 9405.29 (Other), by its specific requirement for LED light source compatibility. While 9405.29 would encompass electric table, desk, bedside, or floor-standing luminaires that can accommodate other types of light sources (e.g., incandescent, halogen, fluorescent) or lack a specific LED-only design mandate, 9405.21 is strictly limited to LED-centric designs. The key differentiator is the manufacturer's intent and the luminaire's inherent design for LED illumination.

Underneath this classification, the subcategory 9405.21.80, "Other," further refines the classification. This suggests that within the realm of LED-compatible electric table, desk, bedside, or floor-standing luminaires, there are further distinctions made, likely based on material composition or other specific functional attributes that are not explicitly detailed at this parent level but are addressed in the more granular sub-classifications.
