Containers & Cargo Equipment
Roll-on/Roll-off
Also known as: Ro-Ro, RoRo
Roll-on/roll-off refers to vessels and services designed so that wheeled cargo — cars, trucks, trailers, buses, and self-propelled machinery — can be driven directly on board through ramps and driven off at destination, without cranes or containers. Ro-Ro is the efficient standard for shipping vehicles and rolling equipment in volume, minimizing handling and loading time. The cargo is secured on the vessel's decks for the voyage, and the method is prized for the speed of loading and discharge, making it central to the global automotive trade and to moving construction and agricultural machinery.
For vehicles the customs and agency work dwarfs the shipping. EPA and DOT conformity, and the export documentation on used vehicles, catch importers far more often than the loading ever does.
Where it matters for compliance
- Vehicle imports carry agency conformity requirements in addition to customs entry.
