9902.16.18 - Power adapters designed for use with standard car cigarette lighter sockets having dual USB output ports with 12 W output per port (provided for in subheading 8504.40.95)

This classification pertains to specialized power adapters designed for automotive use, specifically for connection to a vehicle's cigarette lighter socket. These adapters are characterized by their dual USB output ports, each capable of delivering a 12-watt power output. The intended function is to provide charging capabilities for various electronic devices within a vehicle environment.

Within the Harmonized Tariff Schedule, this specific category is located under Chapter 99, which encompasses temporary legislation and modifications. It is important to distinguish this item from other power adapters that might fall under different HTS chapters based on their primary application or circuitry. For instance, general-purpose power adapters not intended for automotive cigarette lighter sockets would be classified elsewhere. The parenthetical reference to subheading 8504.40.95 indicates that these items are, by default, classified as static converters under heading 8504, but are subject to the provisions of Chapter 99 for temporary or special treatment.

As this is a leaf node within the HTS, there are no further subdivisions. Classification at this level is definitive for power adapters matching the description of having dual USB outputs with 12W per port, specifically intended for use with car cigarette lighter sockets. Any variations in port configuration, power output, or intended use would necessitate re-evaluation of the classification.
