A shipper (also known as a consignor) is a person or a company responsible for organizing and transporting goods from one point to another. Generally, the shipper bears the cost of freight, except otherwise stated in the transport contract before shipment.

The presence of a shipper simplifies the task of a ship owner because the shipper is responsible for ensuring that the cargo arrives at its intended location without incident or mishap. The shipper also handles all documentation required to complete the shipping operation, ensuring that no issues develop during the cargo-delivery process. The bill of lading is one example of such required documents.

Shippers are also responsible for properly packaging and labeling goods and cargo in addition to transporting them. Just as one shipper is in charge of packaging and shipping products from one location to another, another shipper is in charge of receiving cargo at the destination.
