Supply or cargo chains are complex ecosystems involving multiple organizations, infrastructure modes, carriers and workers that comprise the movement of commodities from their point of origin (factory, farm, mine, etc.) to the retailer and consumer. They include beneficial cargo owners (BCOs), ocean carriers, port authorities, regulatory agencies, marine terminal operators, port labor, rail and motor carriers, warehouse, distribution, fulfillment and e-commerce centers and retail businesses. A problem at any link in this chain can cause the entire system to back up.
