C. Free on Board. Free on Board (FOB) is a standard Incoterm (International Commercial Term) which states that the seller is responsible for the goods, and all associated costs and risks, until they are delivered to an independent carrier at a specified point of origin. Once the goods are "on board" the vessel, the risk of loss or damage transfers from the seller to the buyer. The buyer is therefore responsible for the insurance and all costs beyond that point. Cost Insurance Freight (CIF): Under this term, the seller is responsible for the cost of transportation and for paying for insurance to cover the goods to the destination port. However, the risk of loss or damage actually transfers to the buyer once the goods are loaded on board the vessel at the port of origin, just like with FOB.
