The papers that come into play when the cargo reaches its destination show that delivery has been completed in legal terms. The delivery order and the port delivery order allow the carrier or agent to release the cargo to the consignee; the cargo release instruction determines to whom and on what terms delivery is made.
When the cargo is released, its count and condition are checked; the delivery receipt or report is signed after this check. If the cargo is short or damaged, this should be written on the receipt as a remark. If the signature is given without reservation, it becomes harder to claim damage later.
The vessel cargo manifest and the cargo manifest are the lists of cargo the carrier declares to customs; each transport document number corresponds to a line there. If the information in the manifest differs from the paperwork, customs formalities may stall. That is why the document number, the container number and the cargo description should be written identically on all papers.
Expert note: Before signing the delivery receipt, check the number of cartons and their outer condition. Having damage written on the receipt at that moment is far more effective than any correspondence afterwards.
