The document issued to a port authority when goods are deposited is called a dock warrant. A dock warrant is a legal document that certifies that the goods described in it are in the possession of the holder of the warrant, and that the holder has the right to take possession of the goods upon presentation of the warrant. It is often used in international trade as a proof of ownership and as collateral for loans. The port authority uses dock warrants to keep track of the goods that are stored in their facilities, and to ensure that the goods are released only to the rightful owner or holder of the warrant.
