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.
In international shipping, the acronym FOB means free on board. For domestic shipping within the United States it may also be short for freight on board, but that doesn't affect the legal meaning. Used in a shipping agreement, FOB identifies who pays to ship goods and who owns them while they're in transit. The term originated in maritime law, but it also applies to land and air shipments.
