Nigeria Customs Exchange Rate for Import Duty (2026)
Last updated: 8/13/2026 | By Aboki Forex
If you import anything into Nigeria, one number decides a large part of your landing cost, and it has nothing to do with your supplier: the exchange rate Nigeria Customs uses to convert your shipment's value into naira. Duty is charged as a percentage of a naira figure. Move the conversion rate and the naira figure moves with it — same goods, same HS code, bigger bill.
This guide explains which rate applies, where it comes from, how it attaches to your Form M, and how to work out your total duty stack before the goods leave the supplier's warehouse.
Which Rate Does Customs Use?
Customs assesses duty using an official exchange rate published by the Central Bank of Nigeria and applied on the Nigeria Customs Service trade portal. It is not the parallel market rate, and it is not whatever rate you personally paid to buy dollars.
The two rates matter to an importer in different places:
| Rate | Where it applies | Check it here |
|---|---|---|
| Official / CBN rate | Duty assessment, VAT, all percentage levies | CBN official rates |
| Parallel (black market) rate | The dollars you actually buy to pay the supplier | Dollar to naira black market |
| NFEM window rate | Bank-sourced FX, Form A and Form M funding | What NFEM is |
The gap between the first and second row is the importer's structural headache. Duty is computed on an official rate you cannot buy dollars at, while the dollars themselves are often sourced closer to the parallel rate. Both numbers belong in your costing sheet.
How the Rate Attaches to Your Form M
For most commercial imports, the sequence is:
- Open a Form M on the trade portal through your authorised dealer bank, with the proforma invoice and the goods' details.
- Form M is validated by the bank and Customs. This is the point that matters for currency: the assessment basis for the consignment is fixed here rather than floating until arrival.
- PAAR is issued — the Pre-Arrival Assessment Report, which carries the classification, valuation and the applied exchange rate.
- Duty is paid in naira to a designated bank against the assessment.
The practical consequence: the rate on your PAAR is the rate that counts, not the figure circulating in a WhatsApp group on the day your container berths. If you are budgeting a shipment, get the applied rate from the PAAR — or from your clearing agent's assessment print-out — before you argue with anyone about the number.
Historically the duty rate was adjusted at intervals and could sit still for months while the market moved. Since 2024 the CBN has pushed it much closer to the prevailing official closing rate, which removed the old arbitrage but also removed the predictability importers had built their pricing around.
The Full Duty Stack — What You Actually Pay
Import duty alone is never the bill. The standard charges layered onto a Nigerian import:
| Charge | Rate | Calculated on |
|---|---|---|
| Import duty (ECOWAS CET) | 0% – 35% by HS code | CIF value in naira |
| VAT | 7.5% | CIF + duty + surcharge + levies |
| Surcharge (port development) | 7% | The duty amount |
| ETLS levy | 0.5% | CIF value |
| CISS | 1% | FOB value |
| Additional levies / excise | Varies | Specific goods only |
Note what compounds. The surcharge sits on the duty, and VAT sits on almost everything below it. That is why a shift in the exchange rate does not raise your cost by the same percentage as the rate move alone — it raises the base that four other charges are calculated from.
Worked Example
Shipment: $20,000 CIF, 20% duty HS code.
- At a customs rate of ₦1,400/$ → CIF = ₦28,000,000, duty = ₦5,600,000
- At a customs rate of ₦1,550/$ → CIF = ₦31,000,000, duty = ₦6,200,000
- Difference on duty alone: ₦600,000, before the 7% surcharge and 7.5% VAT amplify it
Same container. Same supplier. Same tariff. The rate did all of it. Figures here are illustrative — plug in the current official rate from the CBN rates page and your own HS code percentage.
Where Importers Lose Money
- Quoting customers in naira before the PAAR. If you price a job on last month's rate and clear on this month's, the margin is gone. Quote with a validity window or a rate clause.
- Under-declaring to shrink the naira base. Customs valuation is not taken from your invoice alone; a re-assessment plus demand notice, penalty and demurrage costs far more than the duty you tried to avoid.
- Ignoring the HS code. A neighbouring code can be 5% instead of 20%. Getting classification right legitimately is where the real savings sit.
- Late Form M. Every week the Form M is not open is a week of exchange-rate exposure you did not need to carry.
- Forgetting demurrage compounds the FX problem. Delays at the port cost naira daily while your duty base is already fixed high.
Paying Your Supplier Is a Separate Problem
Duty is one side of the transaction. Actually getting dollars or renminbi to the supplier is the other, and the routes differ sharply in cost and paperwork:
- Form M + Letter of Credit or bills for collection — the documented route, bank-sourced FX, slowest.
- Domiciliary account TT wire — faster, needs you to already hold the currency.
- USDT — used widely for smaller China orders; check the live USDT to naira rate.
- Renminbi settlement — for suppliers who quote and invoice in CNY; see the yuan to naira rate.

Tracking the Rate
Because duty is set on the official market, the number to watch is the CBN rate rather than the street rate — but watching both tells you how much pressure the system is under. Useful pages:
- CBN official exchange rates — the basis for duty assessment
- Dollar to naira black market rate — what your supplier dollars cost
- Commercial bank rates — what your bank will actually sell at
- Naira and forex news — CBN circulars usually land here first
