International trade allows businesses to buy goods from foreign suppliers, sell products to customers in other countries and access markets beyond their home country.
For a Nigerian business, this can mean importing products from China, the UAE, the UK or other markets, or exporting Nigerian products to buyers across Africa and the rest of the world.
But international trade involves more than finding a supplier and arranging shipping. Businesses need to understand customs, product classification, documentation, freight, payments, currency movements and the total cost of getting goods from one country to another.
What Is International Trade?
International trade is the buying and selling of goods or services across national borders.
The two basic forms of goods trade are:
Importing: Bringing goods into your country from another country.
Exporting: Sending goods from your country to buyers in another country.
A Nigerian business can therefore operate as an importer, exporter or both.
For example, a retailer may import electronics from Asia for sale in Nigeria, while an agricultural business may export processed food products to another African market.
Start With Market Research
Before making an international transaction, research the market on both sides of the deal.
If you are importing, find out:
- Whether Nigerians want the product
- Existing local selling prices
- Number of competitors
- Supplier prices
- Shipping costs
- Customs duties and taxes
- Product restrictions
- Expected profit margin
If you are exporting, research the destination market.
Find out who the potential buyers are, what they currently pay, what product standards apply and whether your goods require specific certificates or permits.
A product that sells easily in Nigeria is not automatically suitable for another country.
Find and Verify Trading Partners
Your supplier or buyer can determine whether an international transaction goes smoothly.
Before making a major commitment, verify the business and establish clear commercial terms.
For suppliers, check:
- Company identity
- Product specifications
- Production capacity
- Minimum order quantity
- Quality standards
- Payment terms
- Shipping arrangements
- Previous trading history
For overseas buyers, verify their business identity, purchasing requirements, payment arrangements and ability to complete the transaction.
Do not rely entirely on a professional-looking website or social-media profile as proof that a trading partner is legitimate.
Understand HS Codes
The Harmonized System, commonly called the HS code, is used to classify internationally traded goods.
The classification matters because it can determine the tariff treatment and other requirements applicable to a shipment.
Nigeria Customs provides an official tariff and CET lookup system where traders can search HS classifications, duty information and import or export restrictions. (customs.gov.ng)
Do not simply accept an HS code supplied by a foreign seller without checking it. The correct classification should correspond with the actual nature and use of the goods.
Learn the Customs Requirements
Every country has its own customs procedures.
For Nigerian imports, businesses need to understand requirements surrounding trader registration, TIN, customs declarations, Form M, valuation, assessment and cargo release.
Nigeria Customs states that customs procedures are now handled electronically through its Unified Customs Management System, known as B’Odogwu. Its current guidance also identifies a valid TIN as an important part of trader registration and customs processing. (Nigeria Customs Service)
For exports, businesses also need to understand the documentation and procedures applicable to the particular product and destination.
The exact requirements can change according to the goods, country, value and trade arrangement.
Calculate the Complete Cost
One of the biggest international trade mistakes is looking only at the supplier’s price.
For an import, your real cost can include:
Product cost + freight + insurance + customs duty + applicable taxes and levies + port or airport charges + clearance + storage + inland transportation + final delivery
Nigeria Customs explains that transaction value is the primary basis for customs valuation under the applicable framework, while tariff classification determines the applicable duty rate. (Nigeria Customs Service)
For an export, calculate the cost of sourcing or producing the goods, packaging, documentation, inland transportation, freight, insurance and other applicable expenses before agreeing to a selling price.
Choose the Right Freight Method
International shipments can move through different transportation methods.
Sea Freight
Suitable for many large, heavy or non-urgent shipments.
It is commonly used for containers, machinery, furniture, vehicles and wholesale inventory.
Air Freight
Useful for smaller, urgent or high-value cargo where speed is important.
Road Freight
Important for regional African trade, especially where neighbouring countries are connected by established road corridors.
Multimodal Transport
Some shipments use more than one mode, such as sea freight followed by road transportation to the final destination.
The right choice depends on cargo size, urgency, route, cost and delivery requirements.
Prepare the Necessary Documents
International shipments commonly involve several documents.
Depending on the transaction, these may include:
- Commercial invoice
- Proforma invoice
- Packing list
- Bill of Lading
- Air Waybill
- Certificate of Origin
- Customs declaration
- Import or export permits
- Insurance documents
- Product certificates
- Purchase contract
The exact documentation depends on the product and countries involved.
Information such as the product description, quantity, value and origin should be consistent across the relevant documents.
Understand International Payment Terms
Payment is another major part of international trade.
Common arrangements can include:
- Advance payment
- Deposit and balance payment
- Letter of credit
- Documentary collection
- Other agreed trade-payment arrangements
The appropriate method depends on the relationship between the buyer and seller, transaction size, risk and banking arrangements.
Never treat payment terms as an afterthought. A cheaper supplier may not be the safer transaction if the payment arrangement provides little protection.
Manage Currency Risk
International trade exposes businesses to exchange-rate movements.
A Nigerian importer may have to pay a supplier in US dollars, Chinese yuan, pounds or euros. If the naira value changes between costing and payment, the actual cost of the goods can change.
Exporters face the opposite consideration when receiving foreign currency and converting it into naira.
When preparing prices, allow for realistic exchange-rate movements and avoid calculating profit using an exchange rate that may no longer apply when payment is made.
Check Product Standards and Restrictions
A product may be commercially attractive but still require specific approval before it can be imported or exported.
Depending on the goods, requirements can involve:
- Product standards
- Health certificates
- Food safety requirements
- Labelling
- Agricultural certificates
- Pharmaceutical approvals
- Environmental requirements
- Special licences
Nigeria Customs’ tariff system also provides information on import and export prohibitions and related tariff classifications. (customs.gov.ng)
Check these requirements before purchasing inventory, not after the cargo has already arrived.
Understand Customs Valuation
Customs valuation is important because the customs value can affect the amount of duty assessed on an import.
Nigeria’s current framework applies WTO customs valuation principles through the ECOWAS Common External Tariff and Nigerian customs legislation. Transaction value is the primary valuation method, subject to the applicable conditions and adjustments. (Nigeria Customs Service)
This is why businesses should keep accurate commercial invoices and supporting transaction documents.
Do not assume that simply declaring the lowest possible value will reduce your costs. Customs has authority to examine the accuracy of declarations under the applicable rules. (Nigeria Customs Service)
Plan the Journey Beyond the Port
Getting cargo into a country is only part of international logistics.
An imported shipment may need to move:
Supplier → Export point → International transport → Nigerian port or airport → Customs → Warehouse → Final customer
Every stage can create additional costs or delays.
For example, a container arriving at a Nigerian seaport still needs appropriate transportation from the port to the importer’s warehouse after the relevant clearance and release procedures.
How Travo.ng Can Support International Trade Logistics
Travo.ng can support the transportation and delivery side of international trade where its services are relevant.
An importer may need cargo moved from a Nigerian port or airport to a warehouse, while an exporter may need goods transported from a supplier or warehouse to a seaport, airport or another collection point.
Travo.ng can support relevant cargo transportation, delivery coordination and vehicle-hire requirements, helping businesses manage the inland movement of goods around their wider international shipment.
Travo.ng is not a customs authority, port operator or replacement for a licensed customs agent. Customs declarations, classification, valuation, duties and regulatory approvals remain separate responsibilities handled by the appropriate authorities and authorised professionals.
Common International Trade Mistakes
Focusing Only on the Purchase Price
Always calculate the complete landed or delivered cost.
Choosing an Unverified Trading Partner
Verify suppliers and buyers before committing substantial money or inventory.
Using the Wrong HS Code
Incorrect classification can affect duties and regulatory requirements.
Ignoring Product Restrictions
Check import and export controls before shipping.
Using Poor Documentation
Inconsistent or incomplete documents can delay customs processing.
Forgetting Inland Transportation
Budget for getting the cargo from the port, airport or border to its actual destination.
Promising Customers Unrealistic Delivery Times
International transportation can be affected by customs, port operations, weather, congestion and other factors.
A Simple International Trade Process
For a beginner, the overall process can be simplified to:
Choose product or market → Research demand → Find trading partner → Verify partner → Check regulations → Confirm HS code → Agree price and payment terms → Calculate total cost → Prepare documents → Arrange freight → Complete customs procedures → Clear cargo → Arrange final delivery
For exports, the sequence may begin with identifying the overseas buyer and checking the destination country’s requirements before production or shipment.
Keep Proper Trade Records
Keep copies of every important transaction document.
These can include:
- Contracts
- Invoices
- Payment records
- Shipping documents
- Customs declarations
- Certificates
- Freight invoices
- Duty and tax records
- Delivery documents
Good records make it easier to calculate actual profit, resolve disputes and repeat successful transactions.
Build International Trade Around Reliable Processes
International trade becomes easier to manage when every shipment follows a clear process.
The goal is not simply to find the cheapest supplier or freight rate. A sustainable trading business needs reliable partners, accurate costing, compliant documentation, appropriate transportation and a clear understanding of the destination market.
For Nigerian businesses, using current customs information is particularly important because tariff classifications, procedures and applicable requirements can change. Nigeria Customs currently provides digital trade services, tariff tools and customs guidance through its official platforms. (NCS Tariff & CET Lookup Portal)
When the commercial, regulatory and logistics sides are planned together, international trade becomes much easier to control from the first order to final delivery.
