In the world of international trade, the price on your proforma invoice is just the tip of the iceberg. In Nigeria, “hidden costs” can easily double your expected expenditure if you aren’t careful. In 2026, with the integration of the National Single Window, many manual bribes have disappeared, but system-based costs like demurrage and the new 4% Import Levy have taken their place.
This guide highlights the traps that drain the profits of unsuspecting traders.
1. The Demurrage Trap
Demurrage is the fee you pay the terminal for keeping your container past the “free days” (usually 3–5 days). In 2026, with port automation, the clock starts the moment the ship berths. If your PAAR is delayed by just two days, you could face daily charges starting from ₦50,000 per container. Read how to avoid this in our Guide to Avoiding Port Delays.
2. Shipping Line Detention
While demurrage is paid to the port, Detention is paid to the shipping line for keeping their equipment (the container) too long outside the port. If your warehouse is slow to offload or your truck breaks down, you will pay for every extra day the container is away from the port.
3. The 4% Import Levy (FCS)
Many traders still budget for the old 1% CISS fee. In 2026, this has been replaced by the 4% Import Levy. On a $100,000 shipment, this is a difference of $3,000 (nearly ₦4.5 million). This isn’t strictly “hidden,” but it is a frequent oversight in 2026 business plans. See our 4% Levy Update for details.
4. Inspection and ‘Re-valuation’ Queries
If Customs believes your goods are undervalued, they will issue a Debit Note (DN). This isn’t just a cost; it’s a delay. You must pay the difference before the goods move. To minimize this risk, ensure your HS Code is 100% accurate. Learn more in our HS Code Guide.
5. Bank ‘Sure Fees’ and Forex Fluctuations
When you open a Form M, the exchange rate is locked at the current CBN rate. However, if your clearing process takes too long and the rate moves significantly, some shipping lines and terminals may adjust their local charges. Always add a 5–10% “Forex Buffer” to your budget.
Comparison: Planned vs. Actual Costs
| Item | Planned (Proactive) | Actual (Unprepared) |
|---|---|---|
| Clearance Time | 5 Days | 15 Days |
| Demurrage | ₦0 | ₦500,000+ |
| Detention | ₦0 | ₦250,000+ |
| PAAR Queries | None | ₦300,000 (Adjustment) |
How to Shield Your Profit
- Start Early: Don’t wait for the ship to arrive to process your Form M.

- Get a Licensed Agent: A professional prevents queries that lead to storage costs.
