8701.22.00.80 - Used

This HTS category specifically classifies used road tractors designed for semi-trailers, which are equipped with a dual propulsion system. This system comprises both a compression-ignition internal combustion piston engine (commonly known as a diesel or semi-diesel engine) and an electric motor for their primary motive power. The "used" designation signifies that these vehicles have been previously operated and are now being imported or exported after a period of service.

The key differentiator for this classification lies in the hybrid propulsion. It is distinct from new tractors of the same configuration, which would fall under a separate sibling category. Furthermore, this category is reserved for tractors intended to pull semi-trailers, excluding other types of road tractors or specialized vehicles like those used in industrial settings (which would fall under heading 8709).

As this is a leaf node within the HTS structure, there are no further subcategories for this specific classification. Therefore, classification at this level is determined by the presence of a used road tractor for semi-trailers that simultaneously utilizes both a diesel/semi-diesel engine and an electric motor for propulsion. The condition of the vehicle (used) is a critical factor in its placement here, distinguishing it from new vehicles.
