If you’ve recently looked at a 2026 Customs Assessment, you’ve likely seen two major charges: **Import Duty** and **Import Levy (FCS)**. While they sound similar, they serve different purposes, are calculated differently, and are governed by different laws. Mixing them up can lead to a major shortfall in your clearing budget.
This guide clarifies the distinction between the two in the 2026 trade environment.
What is Customs Duty (Surface Duty)?
Customs Duty is the standard tax charged on goods when they cross the border. It is an **Ad Valorem** tax, meaning it is based on the value of the goods.
- Purpose: To generate revenue and protect local industries from foreign competition.
- Rate: Varies by product (e.g., 5% for machines, 20% for clothes). It is determined by the **HS Code**.
- Calculated On: The CIF (Cost, Insurance, and Freight) value.
Learn more about finding your specific rate in our HS Code Guide.
What is the Import Levy (FCS)?
In 2026, the **Import Levy (FCS)** is an administrative charge that replaced the old 1% CISS fee. It is currently set at **4%**.
- Purpose: Specifically to fund port infrastructure and the National Single Window.
- Rate: Usually a flat rate (4%) regardless of the type of product.
- Calculated On: The FOB (Free On Board) value, not the CIF.

Key Differences at a Glance
| Feature | Customs Duty | Import Levy (FCS) |
|---|---|---|
| Calculation Base | CIF (Cost + Freight + Insurance) | FOB (Cost of goods only) |
| Determination | HS Code (Product Type) | Flat Rate (Policy-based) |
| Standard Rate | 0% – 35% | 4% (in 2026) |
| Regional Origin | Reduced for ECOWAS/AfCFTA | Applied to all non-African imports |
How They Work Together
When you import, you don’t choose between one or the other—you pay both. For example, if you import a car with a 20% Customs Duty, you will pay that 20% on the CIF, AND then pay the 4% Import Levy on the FOB. These amounts, along with the **7% Surcharge** and **7.5% VAT**, make up your total tax bill. See the full calculation in our 2026 Duty Formula Guide.
Common Pitfall: The ECOWAS Exception
One major difference is that while Customs Duty can be 0% for goods from ECOWAS countries (like Ghana or Togo), the Import Levy may still apply to certain administrative categories. Always check your **PAAR** assessment carefully. Read more about PAAR in our PAAR Explained Guide.
Conclusion
Understanding that Customs Duty is product-specific while the Import Levy is an administrative flat fee is vital for accurate budgeting in 2026. For real-time updates on these rates, use the Nigeria Trade Hub or consult the latest Nigeria Customs Service circulars.
