8701.21.00.15 - G.V.W. not exceeding 36,287 kg

This HTS category encompasses new road tractors specifically designed for use with semi-trailers, which are powered solely by a compression-ignition internal combustion piston engine (commonly known as diesel or semi-diesel engines). These vehicles are characterized by their Gross Vehicle Weight (G.V.W.) not exceeding 36,287 kilograms. The primary function of these tractors is to haul semi-trailers on roadways, forming the backbone of many long-haul transportation operations.

The defining criterion that distinguishes this category from its sibling, HTS 8701.21.00.45, is the Gross Vehicle Weight. While both cover new road tractors with diesel engines for semi-trailers, this classification applies only to those with a G.V.W. of 36,287 kg or less. This distinction is critical for customs purposes and often relates to regulatory requirements, licensing, and road usage classifications.

As this is a leaf node within the HTS structure, there are no further subcategories. Classification within this specific code relies entirely on meeting the criteria of being a new road tractor for semi-trailers, powered by a compression-ignition engine, and having a G.V.W. within the specified limit. Practical classification would involve verifying the vehicle's specifications, including its engine type and its declared or actual Gross Vehicle Weight.
