9405.42 - Other, designed for use solely with light-emitting diode (LED) light sources:

This HTS category, 9405.42, encompasses electrical luminaires and lighting fittings that are not elsewhere specified or included, and are specifically designed for use *solely* with light-emitting diode (LED) light sources. This exclusion means that fixtures incorporating or intended for use with other types of light sources, such as incandescent, halogen, or fluorescent bulbs, would not fall under this subheading. The "Other" designation indicates that these are general-purpose LED lighting fixtures not fitting into more specific subcategories.

Distinction from sibling categories is crucial. HTS 9405.41 covers photovoltaic LED lighting, meaning fixtures that integrate solar panels to power the LEDs. Therefore, 9405.42 specifically applies to LED lighting that relies on an external power source and does not have integrated solar technology. The sibling category 9405.49.00.00, "Other," would apply to electric luminaires and lighting fittings where the light source is not exclusively LED, or where the specific design does not meet the criteria of 9405.41 or 9405.42.

This category further divides into subcategories based on material. The subcategories ": Of base metal:" and ": Other:" indicate that the subsequent classification will depend on whether the primary construction material of the luminaire is base metal or a different material. This distinction is important for trade statistics and potential duty rate differences.
