HGL help transportation companies manage incoming and outgoing shipments in airline, or trucking terminals or on shipping docks. Agents expedite shipments by determining a route, preparing all necessary documents, and arranging for the pickup of freight or cargo and its delivery to loading platforms. They may also keep records of the cargo, including its amount, type, weight, dimensions, destination, and time of shipment. They also keep a tally of missing items and record the condition of damaged items.

HGL arrange cargo according to destination. They also determine any shipping rates and other applicable charges. For imported or exported freight, they verify that the proper customs paperwork is in order.

HGL often track shipments electronically, using bar codes, and answer customers' questions about the status of their shipments.
