8703.70.00.90 - Used

This HTS category, 8703.70.00.90, specifically covers **used vehicles that are primarily designed for the transport of persons, excluding those of heading 8702.** The defining technical characteristic is that these vehicles must be equipped with **both a compression-ignition internal combustion piston engine (diesel or semi-diesel) and an electric motor for propulsion.** Furthermore, they must be capable of being charged by plugging into an external source of electric power, indicating they are plug-in hybrid vehicles. This code applies to such vehicles that have a cylinder capacity exceeding 2,500 cubic centimeters, and are not otherwise specifically classified under a more granular subheading.

The distinction from its sibling category, 8703.70.00.70 (New), is solely based on the **condition of the vehicle.** While both subheadings fall under the broader category of plug-in hybrid electric vehicles with diesel engines exceeding 2,500 cc, this specific subheading applies to units that have been previously owned or operated, and are therefore not considered "new" for customs purposes. Classification hinges on the vehicle's status at the time of import.

As this is a leaf node within the HTS, there are no further subcategories to introduce. Therefore, the classification concludes at this level based on the vehicle's propulsion system, engine capacity, operational status (used), and primary purpose of transporting persons. Examples would include used plug-in hybrid SUVs or sedans featuring diesel engines over 2,500 cc.
