Abstract: A shipping harness assembly for use with collapsible containers to permit such containers, when filled with a liquid or dry powdered solid substances, to be "containerized" in cargo boxes for transoceanic movement by boat. The cargo boxes may also be positioned on truck or railway car beds for distribution on land. The shipping harness stabilizes the collapsible container, which is positioned on its side in the cargo box, through the provision of a plurality of straps encircling the collapsible container along its length and a plurality of straps positioned across said encircling straps in a direction generally parallel to the axis of the collapsible container. Each strap is anchored to the floor of the cargo box.
