Cargo Meaning: Types, Documents and Load Costs

Cargo is goods carried for commercial purposes, whether the vehicle is a truck, a van, a train, a ship or an aircraft. The word started out meaning the load of a ship. Today it covers commercial goods on any mode, from a single pallet to a full deck of packed cases.

What is not cargo matters just as much. Crew baggage, the straps and bars carried on board, and the fuel, spares and supplies that keep the vehicle running are not cargo. They travel with the transport rather than being the reason for it. Cargo is the load the transport is run for, and the load the transport document describes. That holds whether a haulier moves the goods for a paying customer or a manufacturer moves its own stock between its own sites.

Cargo, freight, consignment: which word to use

In road transport these words overlap, and the difference is mostly habit. Freight also names the goods, but it names the money as well: you quote freight and you pay freight. Cargo stays with the goods and is rarely used for the charge.

A consignment is the goods of one customer moving under one transport order, from one sender to one receiver. A load is what physically sits on the vehicle, which may be several consignments at once. Shipment is the everyday word for a consignment and travels across all modes.

The main types of cargo

General cargo is packaged goods handled piece by piece: cartons, crates, drums, big bags and anything stacked on pallets. It is the everyday cargo of road transport and it suits a curtainsider or a box body.

Bulk cargo travels loose and unpackaged, poured or pumped into a purpose built body: a tipper for grain and aggregates, a silo for powders, a tanker for liquids. There are no handling units to count, so the load is described by weight or by volume.

Then come the cargoes that dictate the vehicle instead of the other way round. Temperature controlled goods need a reefer body holding a set temperature through the whole chain. Dangerous goods bring their own requirements for packaging, labelling, documentation, driver training and equipment on board. Long, heavy or out of gauge pieces need the right trailer and a route planned around what that combination can physically take.

Cut across those types is how the cargo is bought. A full load takes the whole vehicle from one sender to one receiver. A part load shares the deck with other consignments and is priced on the space it occupies. Containers are a third case: the cargo already sits in its own unit and the road leg carries the box.

Space or weight: what a cargo really costs

A vehicle runs out of one of two things, floor space or payload, and whichever comes first decides the price. Light bulky cargo fills the deck long before the axles are loaded. Dense cargo such as steel or bottled drinks reaches the weight limit with deck space left over.

That is why road cargo is quoted in loading metres as often as in kilos, and why the same pallet count can cost very different money depending on what is on the pallets.

The documents that travel with the cargo

Because cargo moves under a contract of carriage, the carrier issues a transport document: a receipt for the goods and evidence of what was agreed. In sea freight that is the bill of lading, in air freight the air waybill, and in international road freight the CMR consignment note.

The document describes the cargo: what the goods are, how many packages, how they are marked, what they weigh. That description is what the carrier signs for at collection and what the receiver checks on arrival. If a claim follows, the paperwork plus whatever was noted at handover is the story everyone argues from.

Before you accept a cargo

Most cargo problems are settled before the truck moves. Pin down the description first: the nature of the goods, the packaging, the number of handling units and the gross weight per unit. Ask whether the goods are palletised or loose, and who does the loading.

Then look at both ends of the journey: access for the combination you are sending, opening times, whether the site has a ramp or expects the driver to unload by hand, and what waiting time is charged if the ramp is blocked.

Finally, agree what happens when the cargo is not as described. If the pallets stand taller than booked, or a drum arrives leaking, the driver needs to know whether to load, to refuse the goods, or to note the condition on the consignment note and carry on. Writing that into the transport order costs nothing. Discovering it at the ramp costs a day.
