Cambridge O Level Commerce (7100): Logistics in commerce – Study Guide

Logistics is the planning and management of how goods are moved and stored on their way from producers to the people who use them. Topic 4 of the Cambridge O Level Commerce (7100) syllabus has two sections: 4.1 Transport, covering the functions of transport, the five methods, the factors that decide the choice and containerisation; and 4.2 Warehousing, covering the functions and types of warehouse and the use of automation. Exam questions usually give a business situation and ask you to recommend and justify a transport method or a type of warehouse.

Where does Topic 4 fit in the syllabus?

Topic 1 introduced the elements of logistics in a supply chain: transport, freight forwarders and warehousing. Topic 3 showed how global supply chains link suppliers, manufacturers and consumers across countries. Topic 4 looks closely at the two physical activities in those chains, moving goods and storing them. It leads into Topic 5, Aids to trade that support commerce, where insurance protects goods in transit and in storage.

Syllabus coverage (7100, 2026-2028)

Section	What you must know
4.1 Transport	The three functions of transport (time, place and quantity); road, rail, air, sea and pipeline; their advantages and disadvantages; the factors affecting choice (nature of goods, urgency, cost, security, distance and reliability of transporter); containerisation and transshipment
4.2 Warehousing	The functions of warehousing (links with seasonal production and demand, protecting supply, price stability, logistics postponement); bonded, cold storage, cash and carry and regional distribution centre (RDC) warehouses; robotics, automated sorting and voice picking; the benefits of automation

What does transport do in the supply chain? (4.1)

Production and consumption usually happen in different places, so goods must be moved. The syllabus names three functions of transport:

• Time: goods arrive when they are needed, for example fresh fruit reaching a market before it spoils or toys reaching shops before a festival.
• Place: goods are moved from where they are produced to where they are bought, such as copper from a mine to a port or clothes from a factory to a shop.
• Quantity: the right amount arrives, so the business neither runs short nor holds far more than it needs.

What are the methods of transport and their advantages? (4.1)

Method	Examples named in the syllabus	Advantages	Disadvantages
Road	Delivery vans, trucks, couriers	Door-to-door service; flexible routes and times; suits short and medium distances	Congestion and delays; limited load size; pollution; risk of accidents
Rail	Freight trains	Carries heavy, bulky loads cheaply over long land distances; lower emissions per tonne than road	Fixed routes and timetables; usually needs road transport at each end, which adds handling
Air	Freight planes	Fastest over long distances; secure; suits valuable, perishable or urgent goods	Most expensive; limited space and weight; needs airports
Sea	Ferry, tanker, container ship, cargo liner	Cheapest way to carry heavy and bulky goods internationally; very large capacity	Slow; delays at ports and in bad weather; risk of damage or piracy
Pipeline	Oil, gas, water	Continuous flow; low running and labour costs; not affected by traffic	Very high cost to build; carries only liquids and gases; leaks can be hard to find

A tanker carries liquids such as oil in bulk. A cargo liner sails a regular route to a timetable, so traders know when space is available. A ferry carries vehicles and goods on short sea crossings. Many journeys combine methods, for example road to a port, sea to another country and rail inland.

How should a business choose a method of transport? (4.1)

The syllabus lists six factors. Work through the ones that matter in the scenario, then make a clear recommendation.

1. Nature of goods: perishable, fragile, bulky, liquid, hazardous or valuable. Fresh flowers need speed; crude oil suits a pipeline or tanker.
2. Urgency: how quickly the goods are needed. Spare parts for a broken machine may justify air freight.
3. Cost: compared with the value of the goods. Air freight is too expensive for cheap, heavy goods such as bricks.
4. Security: the risk of theft or damage. Valuable electronics may go by air or in sealed containers.
5. Distance: local deliveries suit road; long international journeys suit sea or air.
6. Reliability of transporter: the carrier’s record of delivering on time and without loss.

What is containerisation, and why does it matter? (4.1)

Containerisation means packing goods into standard-sized metal containers that can be lifted by crane between ships, trains and trucks without being unpacked. Transshipment is the transfer of containers from one ship or vehicle to another at a hub port on the way to the final destination; large ships carry containers between hubs and smaller feeder ships take them on to smaller ports.

Advantages	Disadvantages
Loading and unloading are much faster	Containers, cranes and container ports are very expensive
Sealed containers reduce theft and damage	Smaller ports cannot handle large container ships
Lower labour and insurance costs	Empty containers have to be returned, which costs money
Easy transfer between road, rail and sea	Not suitable for every cargo, for example some bulk liquids

Worked example 1: choosing a transport method

A flower grower in Kenya sells fresh roses to a wholesaler in the Netherlands for a festival in five days.

• Nature of goods: perishable and fragile, so they need speed and refrigeration.
• Urgency: high; the roses must arrive before the festival.
• Distance: long and international, which rules out road and rail.
• Cost: air freight is the most expensive method, but roses are high in value for their weight.
• Recommendation: refrigerated air freight. Sea would be far cheaper, but the journey would take weeks and the flowers would be worthless on arrival.

By contrast, a company sending 20,000 tonnes of iron ore from Australia to China would choose a bulk ship: the ore is heavy, cheap for its weight, not perishable and not urgent.

Why do businesses use warehouses? (4.2)

A warehouse stores goods until they are needed. The syllabus names five functions:

Function	How it helps
Links with seasonal production	Crops harvested once a year, such as rice, are stored and sold throughout the year
Links with demand	Goods produced steadily all year are stored and released when demand peaks, for example before a festival
Protecting supply	Stock is kept in reserve so that customers are still supplied if a delivery is delayed
Price stability	Releasing stored goods steadily avoids sharp rises in price when supply is short and falls when supply is plentiful
Logistics postponement	Final steps such as labelling, packing or simple assembly are delayed until orders are known, often at a warehouse near the customer, so stock matches demand

Which types of warehouse are there? (4.2)

• A bonded warehouse stores imported goods on which customs duty has not yet been paid. The importer pays the duty only when the goods are released for sale, which helps cash flow, and pays none if the goods are re-exported.
• A cold storage warehouse is refrigerated or frozen for perishable goods such as meat, fish, dairy products and some medicines.
• A cash and carry warehouse is a self-service wholesaler where small retailers choose goods, pay at once and transport them themselves.
• A regional distribution centre (RDC) is a large warehouse owned by a retail chain. Suppliers deliver full loads to the RDC, which sends mixed loads to the chain’s shops in that region.

How does automation change warehousing? (4.2)

The syllabus names three uses of automation: robotics (robots that move shelves and pick items), automated sorting (conveyors and scanners that route parcels to the right loading bay) and voice picking (workers wear headsets and follow spoken instructions telling them which item to pick from which location). The benefits are lower labour costs, less human error, improved picking accuracy, improved inventory control and improved customer service, because orders are sent faster and correctly. Against this, automation has a high set-up cost, needs skilled technicians and may reduce the number of jobs.

Worked example 2: choosing a warehouse

A supermarket chain with 40 stores in one region imports frozen fish and sells imported spirits.

• The frozen fish must stay frozen from the port to the shelf, so it needs cold storage.
• Supplying 40 stores from one hub, rather than having every supplier deliver to every store, points to an RDC with a cold-storage section. Fewer, fuller journeys cut transport costs.
• The spirits attract high customs duty, so holding them in a bonded warehouse lets the chain pay the duty only as the spirits are released to stores.

What are the common mistakes in Topic 4?

• Recommending air freight as “best” without linking it to the nature of the goods or urgency.
• Forgetting that rail usually needs road transport at each end.
• Describing containerisation without mentioning standard-sized containers and transfer between methods.
• Confusing a bonded warehouse (duty not yet paid) with a cash and carry (a wholesaler).
• Listing automation tools without explaining a benefit.

Frequently asked questions

What are the three functions of transport? Time, place and quantity: transport delivers the right quantity of goods to the right place at the right time.

What is the difference between containerisation and transshipment? Containerisation is the use of standard-sized containers. Transshipment is the transfer of those containers between ships or vehicles at a hub on the way to their destination.

Why do importers use bonded warehouses? Duty is paid only when the goods leave the warehouse, so the importer delays the payment, or avoids it altogether if the goods are re-exported.

What is logistics postponement? Delaying final steps such as labelling or packing until orders are known, so that stock matches what customers actually want.
