This is an ocean shipper or freight forwarder who carries out all carrier services but does not own their vessels.
A Non-Vessel Operating Common Carrier (NVOCC) performs its operations or activities by buying or leasing container space under its House Bill of Lading. The carrier provides transport and logistical services without its vessels by arranging and consolidating shipping for smaller shipments from different customers. The consolidated cargo from multiple shippers forms a larger load that fills a container. The capacity to fill a container helps this carrier type achieve economies of scale and the ability to negotiate better freight rates with the shipping vessel.
