OOG
Container types & equipmentOut of Gauge
Cargo that is too tall, wide, or long to fit inside a standard closed container.
In practice
Shipped on open tops, flat racks, or as break-bulk. Carriers charge extra for the lost adjacent slots, and the cargo needs a stowage plan, lashing, and often a survey. Dimensions must be exact when booking.
