FOB stands for Free On Board or so there is no line item payment by the buyer for the cost of getting the goods onto the transport. There are two possibilities: FOB origin, or FOB destination. FOB origin means the transfer occurs as soon as the goods are safely on board the transport.
FOB is only used in non-containerized sea freight or inland waterway transport. FOB terms do not define transfer of ownership of the goods. The term FOB is also used in modern domestic shipping within the USA to describe the point at which a seller is no longer responsible for shipping cost. Ownership of a cargo is independent from Incoterms.
