A shipper is a person or company that handles the shipping of goods from one place to another.
Shippers must be familiar with the regulations regarding imports, exports and transportation. They must be able to load and unload their cargo safely, and avoid any damage to goods in transit.
Besides transportation, the shipper also has to tag and pack the goods.
Typically, one shipper is responsible for packing and loading the goods, while another is responsible for receiving the goods.
