How to Calculate Customs Duty in Nigeria (2026 Guide)
The exact formula Nigerian Customs uses to assess import duty — with a worked example so you know what to expect before your goods arrive.
One of the most common questions importers ask is: "How much duty will I pay?" Understanding how Nigerian customs duty is calculated helps you budget accurately and avoid surprises at the port. This guide breaks down the full formula with a real worked example.
The Basic Formula
Nigerian customs duty is calculated on the CIF value of your goods:
CIF Value = Cost of Goods + Insurance + Freight
Duty Payable = CIF Value (in Naira) × Duty Rate (%)
Total Payable = Duty + VAT + CISS Levy + Other Levies
Step 1: Determine the CIF Value
The CIF value is the total cost of your goods including:
- Cost (C): The price you paid your supplier for the goods
- Insurance (I): The cost of cargo insurance for the shipment
- Freight (F): The cost of shipping (sea or air freight) to the Nigerian port
The CIF value is converted to Naira using the CBN official exchange rate on the day of assessment — not the parallel market rate. This rate changes daily and is published by the Central Bank of Nigeria.
Step 2: Find Your HS Code and Duty Rate
Every imported product is classified under a Harmonised System (HS) tariff code. The HS code determines the applicable duty rate. Nigerian duty rates range from:
- 0% — Raw materials, essential medicines, agricultural inputs
- 5% — Industrial machinery, capital goods
- 10–20% — Semi-finished goods, general consumer goods
- 35% — Finished consumer goods, luxury items
- 35%+ Levy — Vehicles, beverages, tobacco (additional levies apply)
Incorrect HS code classification is one of the most expensive mistakes importers make. A wrong HS code can result in a much higher duty rate being applied — or in goods being flagged for examination.
Step 3: Add Other Levies
On top of import duty, the following charges apply to most imports:
- VAT (7.5%): Applied on CIF value + duty payable
- CISS Levy (1%): Comprehensive Import Supervision Scheme — applied on CIF value
- ETLS (0.5%): ECOWAS Trade Liberalisation Scheme — for eligible goods from ECOWAS countries
- NXP Levy: For certain exports (if applicable)
- Surcharge: Some products attract additional surcharges
Worked Example
Let's calculate duty on a shipment of electronics (HS code: 85249900, duty rate: 20%):
| Cost of Goods (FOB) | $10,000 |
| Sea Freight | $800 |
| Insurance | $50 |
| CIF Value (USD) | $10,850 |
| CBN Rate (example) | ₦1,600/$ |
| CIF Value (Naira) | ₦17,360,000 |
| Import Duty (20%) | ₦3,472,000 |
| VAT (7.5% of CIF+Duty) | ₦1,562,400 |
| CISS Levy (1% of CIF) | ₦173,600 |
| TOTAL DUTY PAYABLE | ≈ ₦5,208,000 |
* This is an illustrative example. Actual rates and exchange rate will vary. Some goods attract additional levies not shown here.
Other Port Charges (Not Customs Duty)
Beyond customs duty, you should also budget for:
- Terminal handling charges (THC) — charged by the terminal
- Shipping line delivery charges
- Clearing agent fees
- Scanning/examination fees (if selected for examination)
- Demurrage (if goods are not collected within the free period)
- Haulage from port to destination
