8701.22.00.45 - G.V.W. exceeding 36,287 kg

This HTS category, 8701.22.00.45, specifically classifies road tractors designed for semi-trailers that have a Gross Vehicle Weight (G.V.W.) exceeding 36,287 kilograms. These are heavy-duty vehicles built primarily for towing and are distinguished by their powerful internal combustion engines, specifically compression-ignition (diesel or semi-diesel), and the additional presence of an electric motor for propulsion. This hybrid powertrain configuration is a key identifying feature.

The distinction between this category and its sibling, 8701.22.00.15, hinges on the declared Gross Vehicle Weight. While both are road tractors for semi-trailers with hybrid diesel-electric propulsion systems, 8701.22.00.45 is reserved for those with a G.V.W. *above* 36,287 kg, signifying their designation for exceptionally heavy hauling applications. The parent categories indicate these are tractors intended for road use and are not railway or tramway rolling stock.

As this classification represents a leaf node within the HTS, there are no further subcategories. Therefore, classification into this code is dependent on meeting all preceding criteria: being a road tractor for semi-trailers, possessing both a compression-ignition internal combustion engine and an electric motor for propulsion, being new, and crucially, having a G.V.W. that exceeds the specified threshold of 36,287 kg.
