A bill of laing (sometimes referred to as a BOL or B/L) is a document issued by a carrier, e.g. a ship's master or by a company's shipping department, acknowledging that specified goods have been received on board as cargo for conveyance to a named place for delivery to the consignee who is usually identified. A through bill of lading involves the use of at least two different modes of transport from road, rail, air, and sea. The term derives from the noun "bill", a schedule of costs for services supplied or to be supplied, and from the verb "to lade" which means to load a cargo onto a ship or other form of transport.
