Form M Nigeria: The Complete Guide for UK Shippers

If you are shipping commercial goods to Nigeria — stock for a shop, equipment for a business, anything imported for resale — you will run into a document called Form M. It trips up more first-time importers than anything else, because it has to be done before the goods ship, not after they arrive.

This guide explains what Form M is, who needs it, and how it fits into a UK–Nigeria shipment, in plain English.

Quick note: Personal effects and gifts sent to family do not need a Form M. If you are sending a barrel of clothes and food to your mother, you can skip this — see our guide on documents needed to ship from the UK to Nigeria. Form M is for commercial imports.

What is Form M?

Form M is an electronic declaration submitted through the Nigeria Single Window Trade Portal that registers an intended import with the Nigerian authorities before the goods are shipped. It is mandatory for almost all commercial imports into Nigeria, regardless of value and whether or not foreign exchange is involved.

In simple terms: it is Nigeria’s way of knowing what is coming into the country, who is importing it, and how it is being paid for — before it ever leaves the UK.

Form M is valid for 180 days for general goods (360 days for plant and machinery) and can be extended.

Who needs a Form M?

You need a Form M if you are importing commercial goods into Nigeria. This includes:

• Stock and inventory for a business
• Goods imported for resale
• Machinery and equipment
• Raw materials for production
• Commercial quantities of any product

You do not need a Form M for:

• Personal effects and used household items
• Gifts to family (in reasonable, non-commercial quantities)
• Diplomatic goods and certain government imports

The dividing line is purpose and quantity. Fifty new identical phones declared as “personal effects” will not pass — that is a commercial import and needs the proper paperwork.

Who can open a Form M?

This is the part that surprises people. You cannot open a Form M yourself from the UK. It must be opened by:

• A Nigerian-registered company (the importer of record), with a valid Tax Identification Number (TIN), and
• Through an Authorised Dealer Bank in Nigeria (a licensed Nigerian bank that processes the declaration on the Trade Portal).

So the importer in Nigeria — whether that is you, your company, or your customer — needs:

1. A registered Nigerian business with CAC registration
2. A Tax Identification Number (TIN)
3. A relationship with a Nigerian commercial bank that acts as the Authorised Dealer

The bank validates the Form M and links it to the supporting documents.

What documents support a Form M?

When the Form M is opened, it must be accompanied by:

• Proforma invoice from the UK supplier
• Insurance certificate
• Regulatory certificates where the goods require them — for example SONCAP for regulated products, or NAFDAC approval for food, drugs, and cosmetics
• Product Certificate and other agency approvals depending on the goods

Once validated, the Form M generates a number that follows the shipment all the way through to customs clearance at the Nigerian port.

How Form M fits into the shipping timeline

This is the critical bit. The sequence matters:

1. Before shipping — the Nigerian importer opens and validates the Form M through their bank, with the proforma invoice and any regulatory certificates (SONCAP, NAFDAC) attached.
2. Pre-shipment — for regulated goods, a SONCAP certificate is obtained based on the Form M.
3. Shipping — the goods leave the UK with the Form M number referenced on the shipping documents.
4. Arrival — Nigerian Customs assesses duty against the Form M and its PAAR (Pre-Arrival Assessment Report), which is generated from the Form M and final documents.
5. Clearance — duty is paid and the goods are released.

If you ship commercial goods without a valid Form M in place, you risk the goods being held, heavily fined, or refused entry. There is no easy way to fix it after the fact.

Form M and the PAAR

You will also hear the term PAAR — Pre-Arrival Assessment Report. The PAAR is issued by Nigerian Customs based on the Form M and the final shipping documents (commercial invoice, bill of lading, packing list). It states the assessed value and the duty payable, and it is what allows the goods to be cleared.

In short: Form M comes first, PAAR follows, then clearance. They are two stages of the same process.

How Precebol helps

The Form M itself is opened on the Nigerian side by the importer and their bank — that is a regulatory step we cannot do for you, because it is tied to a Nigerian company and TIN. But we make the rest straightforward:

• We prepare and supply the UK-side documents your Form M needs — proforma and commercial invoices, packing lists, insurance certificates, and the shipping documents that reference your Form M number.
• We coordinate SONCAP and other regulatory certificates where your goods require them.
• Our Lagos team works with your clearing agent so the Form M, PAAR, and duty assessment line up and your goods are not held.
• We tell you up front whether your shipment is commercial and needs a Form M — so there are no surprises at the port.

If you are not sure whether your shipment counts as commercial, send us the details and we will tell you exactly what paperwork you need before anything ships.
