The word cargo refers in particular to goods or produce being conveyed generally for commercial gain by ship, boat, or aircraft, although the term is now often extended to cover all types of freight, including that carried by train, van, truck, or container.
Additionally, cargo services involve several processes, including packaging, documentation, customs clearance, tracking, and final delivery. With advancements in technology, cargo companies now provide real-time tracking systems, allowing customers to monitor their shipments from origin to destination.
