Customers that have cargoes that doesn’t fill up a container (and such cargoes can only be moved with a container) but doesn’t want to pay for a Full Load Container (FLC) will choose the option of having other customers cargoes placed into the container and the cost will be shared accordingly amongst them all.
Note that container is processed for shipping when it is filled up.

Our C.G shipping practices allows a number of our customers store pieces of freight within a large container and is transported as a single unit. This practice offers benefits to our customers such as greater cargo protection and reduced shipping costs as the shipping costs is shared accordingly.
