Often regarded as synonymous with CIF in the international cargo trade, its terms differ from the latter in a number of ways. Generally, the seller's risks are greater in a delivered transaction, since the buyer pays on the basis of landed quantity and quality. Risk and title are borne by the seller until such time as the fuel passes from shipboard through the connecting flange of the buyer's shore installation. Also, the seller is responsible for clearance through Customs, and payment of all duties. Any in-transit contamination or loss of cargo are the liability of the seller. In delivered transactions, the buyer pays only for the quantity of oil actually delivered into storage, not the amount of the Bill of Lading.
