Yes. The maintenance and service vehicle heading explicitly covers self-propelled units, and the decisive factor is the vehicle's function (infrastructure maintenance or service) rather than its propulsion. A self-propelled workshop, crane, or tamper is classified here regardless of propulsion, while a self-propelled passenger or freight vehicle falls under the appropriate revenue-service heading.

Standard import documentation applies: commercial invoice, packing list, bill of lading, and a detailed technical description identifying the vehicle as a maintenance or service unit. For high-value capital equipment, importers may also need a CBP ruling or broker opinion confirming the heading, particularly if the vehicle has dual-use characteristics that could place it in an adjacent classification.
