A U.S. Commerce Department document describing all goods exported from the U.S. The shipper of the goods is responsible to make sure the document is filled out correctly, even though it may be done as a service for them by a freight forwarder or an NVOCC. This official document must be submitted by a U.S. exporter whenever a shipment of merchandise goes from the U.S. to a foreign destination. The joint Bureau of Census-International Trade Administration issues this form used for compiling U.S. export control laws. In it the shipper shows the value, weight, consignee, destination, etc., of export shipments as well as the Schedule B identification number.
