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 = Free On Board: This is where the seller is responsible for the costs and risks of getting the goods on board the ship. Once the goods are loaded on the ship, the costs and risks then transfer to the buyer.FR = Cost and Freight: The seller is responsible for the costs (but not the risks) up until the goods arrive in the UK port. The buyer then has to pay all of the costs to get the goods from the port to their premises.
