Cargo shipping businesses transport goods by sea between ports, within the UK and internationally. They may operate vessels or arrange space on ships for businesses and individuals. Freight can include full or part container loads, vehicles, machinery, bulk materials, refrigerated goods and oversized consignments. Services may cover container, roll-on/roll-off, break-bulk and specialist cargo transport, depending on the provider and the route. Customers can expect help with selecting a suitable shipping method, preparing cargo for transit and arranging collection or delivery to and from ports. Some businesses also handle freight documentation, cargo tracking, customs declarations, insurance arrangements and coordination with port or road transport services. Transit times, handling requirements and paperwork vary according to the cargo, destination and shipping service.
