Freight forwarders typically arrange cargo movement to an international destination. Also referred to as international freight forwarders, they have the expertise that allows them to prepare and process the documentation and perform related activities pertaining to international shipments. Some of the typical information reviewed by a freight forwarder is the commercial invoice, shipper's export declaration, bill of lading and other documents required by the carrier or country of export, import, or transhipment. Much of this information is now processed in a paperless environment. A freight forwarder organizes the safe, efficient movement of goods on behalf of an exporter, importer or another company or person, sometimes including dealing with packing and storage. Taking into account the type of goods and the customers' delivery requirements, freight forwarders arrange the best means of transport, using the services of shipping lines, airlines or road and rail freight operators. In some cases, the freight forwarding company itself provides the service. Companies vary in size and type, from those operating on a national and international basis to smaller, more specialized firms, who deal with particular types of goods or operate within particular geographical areas.
