The document summarizes key aspects of free on board (FOB) contracts under international law. It discusses three main types of FOB contracts: (1) the classic FOB where the buyer nominates the ship and seller puts goods on board; (2) the extended FOB where the seller also makes shipping arrangements as principal; and (3) the strict FOB where the buyer is responsible for shipping arrangements. The duties of the FOB buyer include nominating the port and ship, securing shipping space, and contracting for carriage. The duties of the FOB seller include shipping goods of the contract description at the named port.
