8701.29.00 - Other

This HTS category, 8701.29.00, encompasses "other" road tractors designed for semi-trailers. These are distinct from the more specific subcategories within 8701.20, which detail tractors based on their propulsion systems. Specifically, this classification applies to road tractors for semi-trailers that do not solely rely on a compression-ignition internal combustion piston engine (diesel or semi-diesel) as in 8701.21.00, nor are they hybrid diesel-electric (8701.22.00), hybrid spark-ignition-electric (8701.23.00), or purely electric (8701.24.00).

The primary function of these tractors is to provide the motive power to pull a semi-trailer, forming a tractor-trailer unit. Classification here hinges on the absence of the specific engine configurations outlined in the preceding sibling categories. For example, a road tractor powered by a gasoline engine without any electric motor for propulsion would fall under this residual category.

Within this classification, a further distinction is made between new and used vehicles. The subcategory 8701.29.00.80 specifically addresses used road tractors for semi-trailers, allowing for separate statistical tracking and potentially different tariff treatments based on their condition. This ensures that the trade data accurately reflects the age and operational status of the imported vehicles.
