When the goods are loaded on board the ship, the "received for shipment" may be exchanged for bills of lading or converted into a shipped bill of lading or a on board bill of lading, provided that the name of the ship and the date embarkation be noted, together with the necessary clauses about the apparent condition of the cargo. Usually this is done by the agent by means of a stamp: "Shipped on board .... Date ...." followed by his signature or initials. (See "Shipped B/L" .)
This is in accordance with Article 3, paragraph 7, last sentence, of the Hague-Visby Rules:
"....the carrier, master or agent with the name or names of the ship or ships upon which the goods have been shipped and the date or dates of shipment, and when so noted, if it shows the particulars mentioned in paragraph 3 of Article III shall for the purpose of this article be deemed to constitute a "shipped" bill of lading".
The received for shipment bill of lading is often used in the liner trade for the shipment of small lots, which, for reason of stowage, must wait until they can be loaded.
