Cube Out

Cube Out describes a situation where a shipment reaches the maximum available volume capacity of a container, trailer, or aircraft before reaching its weight limit. In this case, no additional cargo can be loaded due to space constraints, even though weight capacity remains. This commonly occurs with lightweight but bulky goods. Cube out impacts freight efficiency and cost, as shippers may pay for unused weight capacity. Proper cargo planning, packaging optimization, and load configuration help reduce the risk of cubing out and improve transport utilization.
