Import Duty in Nigeria Explained: How Landed Cost Works

You have a quotation from a supplier, you know the unit price, and you are about to place an order. Then a friend in Apapa says, "Don't forget the duty." Another says the duty is the smaller part of the bill. A third says the clearing agent's number always comes in higher than the one they promised. As a result, you do not know whether the goods will leave you with a profit or a loss, and you are nervous about asking.

That nervousness is normal. Import duty in Nigeria is only one part of what it costs to bring a product to your shelf, and the way it is worked out can look mysterious until someone shows you the logic. The logic is not hard. Customs authorities generally look at what the goods are, what they are worth, where they come from and what rules apply. Everything else, freight, insurance, handling, agent charges and transport, sits beside the duty in your landed cost.

This guide explains how import duty and landed cost fit together at a stable, well-known level. It deliberately gives no rates or fees, because those change and depend on the product, the date and the rules in force. What it gives you is a method you can use with any clearing agent's figures.

What "landed cost" actually means

Landed cost is the total cost of getting a product from the supplier to your warehouse or shop, ready to sell. It is the number your selling price must beat. If you only compare supplier prices, you are comparing the smallest part of the story.

Landed cost usually includes:

The price you pay the supplier.
Costs in the supplier's country to get goods to the port or airport: packing, inland transport, export paperwork.
International freight.
Insurance on the goods in transit.
Customs duty and other government charges applied at import.
Port or terminal handling and related charges.
The clearing agent's service charge.
Inland transport from the port to your premises.
Bank charges and currency costs on the payment.
Any storage, demurrage or inspection costs if the goods wait.

Duty is one line in that list. For some products, it is a large line. For others, freight or handling matters more. Only a full sheet shows the truth for your goods.

How import duty in Nigeria is worked out, in principle

Without giving any rates, the logic of customs duty is generally built from four ideas.

Classification. Every product is classified under a tariff code, often called an HS code, which is part of an international system for naming goods. The code decides which duty and which rules apply. A cotton T-shirt, a phone charger and a bag of rice all sit under different codes.

Valuation. Customs needs a value on which to apply the duty. Generally this starts from the transaction value, meaning the price actually paid or payable, and the rules may add certain costs such as freight and insurance to reach a customs value at the border. The exact method follows national rules and international valuation principles. This is why your commercial invoice must be accurate and consistent with your payment records.

Origin. Where goods are made can matter. Some trade arrangements treat origin differently, and origin documents may be requested in some cases. Do not assume a preferential treatment applies unless your agent confirms it.

Rules and restrictions. Beyond duty, some goods are restricted, require a permit, or must meet standards. That is separate from duty but affects whether you can import at all.

Your clearing agent applies these ideas to your actual shipment. You do not have to memorise them, but you should understand them well enough to ask good questions.

Duty is not the only government charge

Buyers sometimes say "import duty" when they mean every charge between the ship and the gate. In practice, depending on the goods and the rules in force, there may be several types of charge: customs duty, levies, taxes on imports, and fees tied to specific agencies or services. Port charges and shipping-line charges are separate again.

Because the mix changes with policy, product and time, you should not rely on a rate you saw in a forum. Ask your clearing agent for a written breakdown for your specific goods, showing each line, and ask what could cause the figures to change before the goods arrive.

The documents behind the numbers

Duty and landed cost depend on paperwork that must match. Typical documents in a sea shipment include:

Document	What it does
Proforma invoice	The supplier's quotation, used to apply for import documentation
Form M	The import application processed through the banking system, which your agent or bank helps with
Commercial invoice	The final invoice: description, quantity, unit price, total, currency, Incoterm
Packing list	Carton count, weights, dimensions, contents of each
Bill of lading (sea) or air waybill (air)	The transport document
Certificate of origin	Where goods were made, when requested
PAAR	Pre-arrival assessment report, part of the clearing process, handled by your agent
Product approvals	For regulated goods, such as SON or NAFDAC documents where relevant

If the invoice says one thing, the packing list says another and the bill of lading says a third, the clearing process slows down and costs rise. Accuracy is cheaper than correction.

Rules, fees and procedures change. Confirm current requirements with a licensed clearing agent or customs broker, your bank and the Nigeria Customs Service or other relevant authority before you commit to an order.

Why the Incoterm changes your landed cost

An Incoterm is a standard trade term that says who pays for what and who carries risk at each stage. In plain language:

EXW (ex works): you take the goods at the supplier's door and arrange everything from there.
FOB (free on board): the supplier delivers to the departure port and loads the goods; you pay the main freight from there.
CIF (cost, insurance and freight): the quoted price includes freight and insurance to the destination port; you pay Nigerian charges after arrival.
DAP/DDP: the seller delivers to a named place, and under DDP also handles import clearing. These terms need care, because it must be clear who is legally responsible in Nigeria.

Two quotes can look the same and cost very different amounts because they use different Incoterms. Always ask what the term includes, name the port or place, and convert every quote into the same basis before comparing.

Building your landed-cost sheet, step by step

Here is a method that works for a first-time importer. Use a spreadsheet, leave cells blank until you have written quotes, and fill them honestly.

List the product and the unit. Per piece, per carton or per container.
Enter the supplier price in the quoted currency, with the Incoterm.
Add costs to the port that the quote does not include.
Add international freight and insurance from written forwarder quotes.
Ask your clearing agent for the classification and the government charges for that code, in writing.
Add port and terminal handling and the agent's charges.
Add inland transport to your shop or warehouse.
Add bank and currency costs.
Add a buffer for delays, inspection or storage.
Divide by the number of sellable units to get landed cost per unit.
Compare with your intended selling price and check the margin after your own operating costs.

Comilmart also offers a landed-cost calculator and shipping rate tools that can help you structure this sheet. Treat them as a way to organise your thinking, and use your agent's current figures for the final decision.

Common reasons landed cost surprises buyers

Wrong classification. Describing the goods vaguely or under the wrong code can lead to reassessment.
Undervalued invoices. Declaring a lower value than you paid is risky. Customs authorities can challenge values, delay cargo and penalise, and the practice can cause serious trouble.
Missing approvals. Regulated goods without the right approvals can be held.
Storage and demurrage. Delay in documents leads to extra days at the port, and extra days cost money.
Currency movement. The price in naira terms can shift between order and payment.
Underestimating weight or volume. Freight is charged on actual weight or volume, whichever the carrier applies. Wrong cartons mean wrong cost.
Forgetting the last mile. Trucking from the port to Ikeja, Onitsha or Kano can be a real line.
Hidden extras. Ask agents and forwarders for a complete list of what their quote excludes.

A worked example in words: Import Duty in Nigeria

Suppose you want to import ceramic floor tiles for a building-materials shop in Abuja. The supplier quotes per square metre on an FOB basis. You turn that into a per-carton and per-container figure, since freight is by container, not by square metre. Your forwarder quotes sea freight and insurance. Your clearing agent identifies the tariff classification and tells you in writing which government charges apply and which approvals may be needed for tiles. You add port handling, the agent's charge, a margin for breakage during unloading and trucking to Abuja. Divided by sellable square metres, the tile that looked cheap turns out to cost noticeably more once landed, but still gives you a margin. You also notice that choosing a smaller tile size would waste less in the container, so you ask the supplier to quote that too. The sheet changed what you ordered, not just whether you ordered.

What to do first this week: Import Duty in Nigeria

Pick one product you want to import and write its description in plain words.
Ask a licensed clearing agent for its classification and a written list of charges that apply.
Ask a forwarder for written freight and insurance quotes using realistic carton counts and weights.
Build the landed-cost sheet above with every line filled from written quotes.
Ask your supplier to quote the same item on two Incoterms.
Decide your minimum acceptable margin before you place any order.

Frequently asked questions

How is import duty in Nigeria calculated?

In principle, customs applies a duty to a declared value according to the goods' classification, subject to the rules in force. The rate and any additional charges depend on the product and the date, so ask a licensed clearing agent for a written breakdown.

Is landed cost the same as import duty?

No. Landed cost includes the supplier price, freight, insurance, duty and other government charges, handling, agent fees and transport. Duty is only one part of it.

Can I reduce the duty I pay?

Do not try to undervalue goods or misdescribe them, as that can lead to penalties and seizure. Legitimate options include checking the correct classification, understanding any lawful incentives with your agent, and choosing efficient packing and shipping.

Do small shipments pay import duty?

It depends on how the shipment enters the country and the rules in force. Courier and cargo routes can be treated differently, so confirm the current approach with your agent or courier before ordering.

Who should I ask about duty on my goods?

A licensed clearing agent or customs broker, and where needed the Nigeria Customs Service. Ask for the answer in writing and for the date it applies from.
