How to avoid demurrage at Nigerian ports

Demurrage is the quietest way to lose money on an import. There is no defect, no bad supplier, no theft. Your goods simply sit at the port a few days too long, and the daily charges eat the margin you worked to protect. The frustrating part is that it is almost entirely preventable, because demurrage is rarely a customs problem. It is a preparation problem.

What demurrage actually is

When your container arrives, you get a window of free time to clear and take delivery before charges begin. The exact free period depends on the shipping line and terminal, and it is short, often a handful of days. Once it expires, you pay per container, per day, and the meter does not stop until the box leaves.

There can be more than one clock running: charges from the shipping line for the use of the container, and storage charges from the terminal for the space your cargo occupies. They are separate bills with separate free periods, and both reward speed and punish delay. It is entirely possible to clear the line's free time and still run into terminal storage, or the reverse, so it pays to know both windows for your specific shipment.

The charges are also not flat. They typically escalate the longer the cargo stays, so a delay that starts small can grow quickly if it drags on. This is why a container that overstays by a week can cost far more than one that overstays by a day, and why catching a delay early is so much cheaper than letting it run.

What pushes cargo past its free time

The causes are predictable, which is good news, because predictable problems can be prepared for:

• Documents arrive late or disagree. A missing certificate or a mismatch between invoice and packing list stalls release.
• Form M or PAAR not ready. If the front-end paperwork was opened late, the back end cannot move.
• Duty not funded in time. If the money is not ready when the assessment lands, the cargo waits.
• A query or examination. A questionable value or classification triggers a closer look, and looks take days.
• System or operational delays at the port that are outside your control but that punctual preparation absorbs.

Prepare so the clock never beats you

Treat the free time as fixed and work backwards from it:

1. Get your full document set to your agent before the vessel arrives, complete and consistent. Use the document checklist.
2. Open Form M early and confirm PAAR is issued before arrival, not after.
3. Have duty and charges funded so payment is never the hold-up.
4. Make sure value and classification are right the first time to avoid a query you could have prevented.
5. Stay reachable. Some decisions need your sign-off within hours, not days.
6. Pick an agent who works your terminal routinely, as covered in choosing a clearing agent.

Free time is a gift you only keep if you were ready before the ship arrived. Everything that causes demurrage happens upstream of the port.

The honesty angle

It is tempting to think shaving the declared value saves money. In practice it invites the query that costs you days of demurrage, on top of any penalty. An honest declaration, backed by your supplier's invoice and your payment proof, clears faster precisely because there is nothing to argue about. The few naira you might save by understating value are dwarfed by the daily charges that pile up while an officer examines a file that does not add up. Speed through the port is itself worth money, and honesty is the fastest route.

Watch the calendar, not just the documents

One cause of demurrage has nothing to do with paperwork: timing your shipment into a period when the port or your agent cannot move quickly. Public holidays, the run-up to the Chinese New Year rush of arrivals, and known congestion periods all eat into effective free time. If your goods land just before a long break, the free-time clock keeps ticking while everything around it slows down.

You cannot always control arrival dates, but you can be aware of them. Ask your forwarder when the vessel is expected to berth, and check that window against the calendar. If it looks tight, get every document and the duty funds in place even earlier than usual.

A simple rule of thumb

If your paperwork is complete and consistent, your duty is funded, and your agent has it all before arrival, demurrage rarely happens. If any one of those is missing, the clock starts working against you. It really is that binary: preparation costs nothing and prevents the charge, while improvisation at the port is where the money leaks out.

Free time is short and the charges add up quickly, so the cheapest day at the port is the one you never spend. Confirm current free-time windows and charges with your shipping line and terminal, since they vary by carrier, by terminal and by the size of your container. The importer who knows their exact clock can plan to beat it; the one who guesses usually loses.

Funding part of that preparation, the payment to your supplier, is something you can sort early. You can make a request to settle them in RMB on Alipay from Naira and have the receipt ready for the file long before the vessel docks.
