8701.29.00.45 - G.V.W. exceeding 36,287 kg

This HTS category, 8701.29.00.45, specifically classifies road tractors designed for use with semi-trailers, where the Gross Vehicle Weight (G.V.W.) of the tractor itself *exceeds* 36,287 kilograms. These are heavy-duty prime movers intended for hauling large, specialized cargo over significant distances, and their substantial weight is a primary defining characteristic for this classification.

The key distinction for this category lies in its weight threshold. It is differentiated from its sibling category, 8701.29.00.15, which covers similar road tractors but with a G.V.W. *not exceeding* 36,287 kilograms. Therefore, any road tractor for semi-trailers with a G.V.W. of 36,288 kg or more would fall under this specific classification.

As this is a leaf node within the HTS, there are no further subcategories. Classification at this level is solely determined by the gross vehicle weight of the road tractor, assuming it meets the criteria for a road tractor for semi-trailers and is new. Importers and exporters should ensure accurate G.V.W. documentation is available to support classification under this code.
