Physical characteristics
The physical characteristics that you specify for a container are used to determine its basic physical capabilities.
If you specify that a container can carry a weight of up to 20 kilos, and the item you are shipping weighs 50 kilos, this container cannot be used. If multiple items are being containerized, the container’s volume determines if it can hold all the items.
Note: Some of the items that are being containerized
may be in boxes or have regular shapes, such as books. This simplifies
the calculations about whether a container can successfully hold them.
