Foreign trade: imports, exports and entrepôt trade

By the WASSCE Tutor team

Updated 12 November 2026 · 6 min read · Prepared against the WASSCE syllabus.

The rice in your pot may have come from Asia, the fuel in the bus from the Middle East and the phone in your pocket from China, while Sierra Leone's iron ore and cocoa travel the other way. Trade across borders brings goods no country could make alone, but it also brings extra difficulties. This lesson explains foreign trade and how traders overcome its problems.

Learning objectives

By the end of this lesson you should be able to:

  • define foreign trade and describe import, export and entrepôt trade
  • distinguish foreign trade from home trade
  • explain the reasons for and advantages of foreign trade
  • explain the difficulties of foreign trade and how they are overcome

What is foreign trade?

Definition

Foreign (international) trade is the buying and selling of goods and services between countries.

Sierra Leone importing goods from Country A and exporting to Country B; in entrepôt trade, goods from Country D pass through Sierra Leone and are re-exported to Country C

Figure 1. Import, export and entrepôt trade. WASSCE Tutor diagram.

TypeMeaningExamples for Sierra Leone
Import tradeBuying goods and services from other countriesRice, fuel, vehicles, machinery, medicines, cement
Export tradeSelling goods and services to other countriesIron ore, rutile, bauxite, diamonds, gold, cocoa, coffee, cashew
Entrepôt (re-export) tradeImporting goods and re-exporting them to other countries, often with little processingGoods passing through a West African port to a landlocked neighbour

Visible trade is trade in goods; invisible trade is trade in services (shipping, insurance, banking, tourism).

Home trade and foreign trade

Home tradeForeign trade
Within one countryBetween countries
One currencyDifferent currencies must be exchanged
Same language, laws and customsDifferent languages, laws and customs
Shorter distances; lower transport costsLonger distances; higher transport and insurance costs
Few documentsMany documents (bill of lading, certificate of origin, customs forms)
No customs duties at bordersImport and export duties, quotas, licences
Less riskGreater risks: delays, damage at sea, non-payment
Payment is simplePayment needs foreign exchange, letters of credit or bills of exchange

Why countries trade

  1. Unequal distribution of natural resources: Sierra Leone has iron ore and rutile; other countries have oil.
  2. Differences in climate: tropical crops (cocoa, coffee) and temperate crops (wheat, apples).
  3. Differences in skills, capital and technology: some countries make machinery and vehicles more cheaply.
  4. Specialisation: countries gain by producing what they do best and trading for the rest.
  5. Surplus production that cannot all be consumed at home.

Advantages of foreign trade

  1. Countries obtain goods they cannot produce (or produce only at great cost).
  2. Wider markets for producers, allowing large-scale production.
  3. Earns foreign exchange to pay for imports.
  4. Government revenue from import and export duties.
  5. Higher living standards: variety of goods for consumers.
  6. Spreads technology and ideas.
  7. Creates jobs in ports, transport, banking, insurance and processing.
  8. Promotes international cooperation (for example through ECOWAS).

Difficulties of foreign trade and their solutions

DifficultyHow it is overcome
Different currenciesForeign exchange from banks; payment through banks

Distance and long delaysAir and sea transport, containerisation, courier services
Risk of loss or damageMarine and transit insurance
Risk of non-paymentLetters of credit, bills of exchange, del credere agents
Many documents and proceduresClearing and forwarding agents
Customs duties and trade restrictionsCustoms agents; trade agreements (ECOWAS)

Lack of information about foreign marketsChambers of commerce, embassies, trade fairs, export promotion agencies
In Sierra Leone

Sierra Leone's exports are dominated by minerals (iron ore, rutile, bauxite, diamonds and gold), with cocoa, coffee and cashew as important farm exports. Its imports are mainly food (especially rice), fuel, machinery, vehicles and manufactured goods. The Sierra Leone Investment and Export Promotion Agency (SLIEPA) helps local firms find export markets.

Common mistake

Entrepôt trade is not the same as ordinary exporting. In entrepôt trade the goods were imported first and are then re-exported, often with little or no processing.

Key points

  • Foreign trade is trade between countries: import, export and entrepôt trade.
  • It differs from home trade in currency, language, distance, documents, duties and risk.
  • Countries trade because of differences in resources, climate, skills and technology.
  • Its difficulties are overcome by banks, insurance, agents, transport, documents and trade agreements.

WASSCE examination focus

WAEC tests this

Expect to distinguish home trade from foreign trade, to state the advantages of foreign trade, and to explain the problems of foreign trade and how they are solved. A two-column table for differences, and "difficulty → solution" pairs, are the clearest way to answer.

Quick check

  1. What is entrepôt trade?
  2. Give three differences between home trade and foreign trade.
  3. Give two of Sierra Leone's main exports and two main imports.
  4. How do traders overcome the risk of non-payment in foreign trade?

Answers: 1. Importing goods and re-exporting them to another country, often with little processing. 2. Any three: currency, language, distance, documents, customs duties, risk, laws, payment methods. 3. Exports: any two of iron ore, rutile, bauxite, diamonds, gold, cocoa, coffee, cashew. Imports: any two of rice, fuel, machinery, vehicles, manufactured goods. 4. By using letters of credit, bills of exchange or del credere agents.
