The words on your quote, explained.

Payload is the mass of cargo a vehicle may legally carry — the difference between its gross vehicle mass and its tare weight. An "8-ton truck" describes its payload, not the mass of the truck.

Why it matters: This is the number that decides whether your load goes on one truck or two, and it is the number most often quoted loosely by transporters.

Gross vehicle mass is the maximum total mass a vehicle may weigh when loaded, including the vehicle itself, its fuel, its driver and its cargo. It is set by the manufacturer and enforced at weighbridges.

Tare weight is the mass of a vehicle empty, with no cargo. Payload plus tare equals gross vehicle mass, which is why a heavier truck can legally carry less.

Rear overhang is how far a load extends behind the rear axle of a vehicle. South African regulation limits it in relation to the wheelbase, and loads beyond the limit require abnormal-load permits rather than simply a warning flag.

Why it matters: A long load can be well within payload and still be illegal on overhang. This is the single most common reason a load that "obviously fits" cannot legally be carried.

An abnormal load is freight exceeding the legal limits for mass, width, length or height, requiring a permit and often escort vehicles and route approval. Abnormal-load work is a specialised discipline with its own equipment and permits.

Why it matters: River Express does not carry abnormal loads and says so. A transporter who agrees to take one without mentioning permits is either inexperienced or planning to run it illegally.

A full truck load is freight that takes a whole vehicle, moving directly from collection to delivery without sharing space or stopping at a depot. It is faster and handled less, which means less opportunity for damage.

Less than truck load is freight that shares a vehicle with other consignments, usually routed through a depot to be combined. It is cheaper per item and slower, with more handling and therefore more risk of damage.

A lane is a regular origin-to-destination route, such as Johannesburg to Durban. Transporters price by lane because the economics depend on whether there is freight to carry on the way back.

Why it matters: Asking for a rate "per kilometre" usually produces a worse answer than asking for a rate on a named lane, because the return leg is where the money is actually made or lost.

A backhaul is the return journey after a delivery. When it runs empty the cost is already committed, which is why capacity on a return leg can be offered more cheaply to a customer who is flexible about timing.

Line haul is the long-distance leg of a journey between two centres, as distinct from collection and delivery at either end. Most of the cost of a long move sits here.

Last mile is the final delivery leg from a depot or drop point to the receiving address. It is disproportionately expensive relative to its distance because it involves waiting, access constraints and one delivery at a time.

Demurrage is a charge for a vehicle waiting beyond an agreed free period at collection or delivery. It exists because a truck standing at a gate is a truck not earning, and the cost falls somewhere whether or not it is named on the quote.

Why it matters: Check whether a quote includes free standing time and how long. A cheap rate with thirty minutes of free time can end up dearer than a higher rate with two hours.

Cross-docking is transferring freight directly from an inbound vehicle to an outbound one with little or no storage in between. It reduces warehousing cost and adds a handling point where damage can occur.

A third-party logistics provider is a company that carries out logistics functions — transport, warehousing, distribution — on behalf of another business rather than that business running its own fleet.

A cross-border road transport permit is issued by South Africa’s Cross-Border Road Transport Agency and is required to operate a goods vehicle for hire or reward across the country’s borders. It is a legal requirement, not an optional convenience.

The SAD 500 is the standard customs declaration form used in South Africa and several neighbouring countries to declare goods being imported, exported or moved in transit. It is normally lodged by a clearing agent.

A certificate of origin states where goods were produced. Under the SADC trade protocol, presenting a valid SADC certificate of origin is what earns the preferential duty rate rather than the full one.

Why it matters: Missing this form does not stop the load. It simply means paying full duty — money handed over for a piece of paperwork nobody prepared.

The COMESA Yellow Card is a regional third-party motor insurance certificate recognised across COMESA member states, including Zimbabwe, Zambia, Malawi and the DRC. Where accepted it removes the need to buy separate cover at each border.

A temporary import permit authorises a foreign-registered vehicle to enter a country for a limited period without paying import duty on the vehicle itself. It is issued at the border and surrendered on the way out.

The Southern African Customs Union is a common customs area comprising South Africa, Botswana, Lesotho, Namibia and Eswatini. Goods moving between members do not attract customs duty, which makes those the simplest crossings from South Africa.

Incoterms are standardised international trade terms — such as EXW, FCA, DAP and DDP — defining where responsibility, cost and risk pass from seller to buyer. They determine who arranges and pays for transport at each stage.

Why it matters: Two parties who have not agreed the Incoterm have not agreed who is paying for the freight, and will discover this at the worst moment.
