8701.23.00.45 - G.V.W. exceeding 36,287 kg

This HTS classification, 8701.23.00.45, specifically designates road tractors intended for semi-trailers that are equipped with both a spark-ignition internal combustion piston engine and an electric motor for propulsion. A defining characteristic of this subcategory is that these vehicles have a Gross Vehicle Weight (G.V.W.) exceeding 36,287 kilograms. These tractors are designed for heavy-duty hauling operations on public roads, combining the power and range of traditional internal combustion engines with the efficiency and torque of electric motors, often in hybrid configurations.

The key differentiator for this specific code is the Gross Vehicle Weight. It is distinct from its sibling category, 8701.23.00.15, which covers road tractors of the same hybrid propulsion type but with a G.V.W. not exceeding 36,287 kilograms. Therefore, when classifying a vehicle under heading 8701.23.00, the precise G.V.W. is crucial for determining the correct tariff treatment. Both categories fall under the broader umbrella of road tractors that utilize a combination of internal combustion and electric propulsion.

As this HTS code represents a leaf node, there are no further subcategories for this specific classification. The classification is complete at this level, indicating that goods meeting the described criteria of being a road tractor for semi-trailers, employing both spark-ignition internal combustion and electric propulsion, and exceeding a G.V.W. of 36,287 kg, are fully accounted for. Examples would include heavy-duty hybrid prime movers used in long-haul trucking where significant towing capacity and advanced emission controls or fuel efficiency are required.
