Form M and PAAR explained for importers

Two documents sit at the front of every commercial import into Nigeria. Here is what Form M and PAAR are, the order they come in, and why they matter.

Import paperwork stacked on an office desk

Most new importers think the customs process starts when the goods reach Lagos. It does not. For a commercial import, it starts before the supplier in China has even packed the carton, with a document called Form M. Skip it, and your goods can sit at the port with nowhere to go, because the paperwork that should have begun months earlier was never opened.

What Form M is

Form M is the import declaration you open through a Nigerian bank before your goods ship. It tells the authorities what you intend to import, from whom, at what value, and how the import will be funded. For commercial consignments above a low threshold value, it is mandatory.

You do not file it directly with Customs. You file it through your bank, which acts as the authorised dealer for the transaction. The bank checks your documents, confirms the description and value make sense, and transmits the approved Form M into the national trade platform that links the bank, Customs and the other agencies involved.

To open one you typically need a proforma invoice from your supplier and the relevant regulatory documents for your product, including a product certificate where the goods are regulated. Get your HS code classification right at this stage, because it travels with the file all the way to the port.

Once approved, a Form M is valid for a defined period, after which it can usually be extended through the same bank if your shipment is delayed. That window matters when you are ordering goods that take weeks to manufacture, so plan your Form M timing around your supplier's real production schedule, not an optimistic one. Confirm the current validity period and extension rules with your bank, since they are set by policy and can change.

What PAAR is

PAAR stands for Pre-Arrival Assessment Report. Once your Form M is approved and you have your final shipping documents, the bank submits them and Customs issues the PAAR. It is, in effect, Customs telling you in advance how your goods are classified and valued for duty before the vessel arrives.

The PAAR is the document your clearing agent uses to lodge the actual declaration and work out what you owe. Without it, there is no clean way to clear a commercial consignment.

The value of getting an assessment before arrival is that there are no surprises at the gate. You know the classification and the value the duty will be built on while the vessel is still at sea, which means you can have the funds ready and your agent briefed. An importer who waits until the goods land to discover how they were assessed has already given away time they did not need to lose.

The sequence, in order

The logic only makes sense when you see the whole chain:

  1. Get a proforma invoice from your supplier with a clear description, quantity and value.
  2. Open Form M through your bank, attaching the proforma and any product certificate.
  3. Bank validates and transmits the Form M to Customs through the trade platform.
  4. Goods are produced and shipped. Your supplier finalises the commercial invoice, packing list and bill of lading.
  5. Final documents go to the bank, which submits them for assessment.
  6. Customs issues the PAAR, setting the classification and value.
  7. Your agent clears the goods using the PAAR and your full document set.
Form M is opened before the goods move; PAAR is issued before they arrive. If you remember nothing else, remember that both come early.

Why the bank sits in the middle

The bank is not a rubber stamp. As the authorised dealer it is responsible for confirming your documents are genuine and your declared value is reasonable. This is why your descriptions and figures need to be honest and consistent across every document. A proforma that says one thing and a commercial invoice that says another invites questions you do not want at this stage.

It is also why your payment record matters. The amount you actually paid your supplier should line up with the value on your Form M and invoice. A clean payment paper trail supports the figure you declared, and a mismatch between what you paid and what you declared is exactly the sort of inconsistency that slows a file down.

Common ways importers trip up

  • Opening Form M too late. It belongs at the start, not after shipment. Late filing is a classic cause of cargo stuck at the port.
  • Vague goods descriptions that do not match the eventual invoice and packing list.
  • Forgetting a required product certificate, which holds up the Form M for regulated goods.
  • A declared value that does not match what was paid. Confirm current thresholds and requirements with your bank or the Nigeria Customs Service, as they change.

Form M and PAAR feel like bureaucracy, and they are, but they are also the rails the rest of your clearance runs on. Get them right and the port becomes routine. Get them wrong, or late, and every other thing you did well, the good supplier, the smart freight choice, the funded duty, is held hostage by a piece of paper that should have been sorted at the start.

When the time comes to pay your supplier so the proforma can become a real shipment, you can make a request to settle them in RMB on Alipay from Naira, and keep the receipt with the file your bank will ask for.
