If you are importing commercial goods into Nigeria, Form M is one of the documents you need to understand before your supplier ships.
It sits near the beginning of the import process and connects information about the importer, overseas supplier, goods, value, payment arrangements and regulatory approvals with the Nigerian banking and Customs systems.
Waiting until cargo is already on the water before dealing with Form M can create serious problems later, particularly when you need a Pre-Arrival Assessment Report or want to clear the goods through Customs.
This guide explains what Form M is, what importers need to prepare and how the process currently works in Nigeria.
What Is Form M?
Form M is an electronic import documentation requirement used for goods entering Nigeria.
The current CBN Forex Manual provides the foreign-exchange framework surrounding Form M and other international trade transactions.
Form M is required for imports whether or not the importer intends to obtain foreign currency through the official foreign-exchange market.
In practical terms, Form M creates an official record of the proposed import transaction before the goods arrive.
It captures information such as:
- Importer’s details
- Overseas supplier
- Goods description
- HS codes
- Quantity
- Value and currency
- Country of origin
- Shipping information
- Payment method
- Authorised dealer bank
It then becomes an important reference for later stages of the import process.
Who Needs Form M?
Businesses intending to import physical goods commercially into Nigeria generally need to process Form M through an authorised dealer bank.
This applies whether the goods are being purchased using foreign exchange sourced through the Nigerian banking system or another permitted source of funds.
However, Form M does not mean every product is automatically allowed into Nigeria.
Before starting, an importer should confirm that the goods:
- Are not prohibited
- Have the correct HS classification
- Meet applicable Nigerian standards
- Have the required product permits
- Can legally be imported by the business
The official Nigeria import procedure places product classification and regulatory approvals before or alongside the Form M stage.
What Do You Need Before Applying?
The documents required depend partly on the product.
However, the main Form M supporting documents generally include:
Proforma Invoice
Your overseas supplier issues the proforma invoice before shipment.
It should clearly state details such as:
- Supplier
- Buyer
- Product
- Quantity
- Unit price
- Total value
- Currency
- Incoterm
- Country of origin
Check the invoice carefully before using it for Form M.
The product description and value entered on Form M should remain consistent with the later commercial and shipping documents.
Insurance Certificate
Marine insurance documentation is generally part of the Form M supporting pack.
The details should correspond with the import transaction.
Regulatory Certificate or Permit
The exact document depends on the goods.
For example, regulated products may require documentation from:
- Standards Organisation of Nigeria
- NAFDAC
- NESREA
- Agricultural authorities
- Other relevant regulators
For SON-regulated products, the Product Certificate or appropriate Import Permit may be needed before Form M can proceed.
The official Customs service standard lists the proforma invoice, insurance certificate and applicable regulatory certificates among the core documents for Form M registration.
Step 1: Register Your Business for Importing
Before processing Form M, a commercial importer should have the basic business and tax registrations required to trade.
This normally includes:
- CAC registration
- Tax Identification Number
- Bank account with an authorised dealer bank
- Registration on applicable trade platforms
The official trade guide currently directs importers to register on both the National Single Window and B’Odogwu platforms.
The TIN is particularly important because it connects the importer across the electronic Customs process.
Step 2: Confirm the Correct HS Code
Your HS code determines much more than the Customs duty rate.
It may also determine:
- Whether the goods are prohibited
- Applicable import duties
- Levies
- Regulatory agencies
- Required permits
- Product standards
Do not choose an HS code simply because another importer uses it for a similar product.
Use the actual composition and function of your goods.
The Trade Information Portal allows businesses to research product-specific requirements and applicable trade procedures.
Step 3: Obtain Required Product Approvals
Some imports require regulatory approval before the Form M application can be completed.
For example, an electrical product may require SON-related conformity documentation, while food or pharmaceutical products may involve NAFDAC.
Nigeria’s 2026 National Single Window rollout has moved several regulatory licence, permit and certificate processes into one central environment.
This means an importer may interact with the National Single Window for a product permit and B’Odogwu for the Form M and later Customs stages.
Do not assume that Form M replaces the product licence.
They serve different purposes.
Step 4: Submit Form M Through Your Bank
The importer applies for Form M through an authorised dealer bank.
Current government guidance states that Form M applications are made through authorised dealer banks on the B’Odogwu platform.
You will provide details of the transaction and upload the required supporting documents.
The bank reviews the application as part of its trade and compliance process.
This may include checking:
- Importer’s identity
- Supplier details
- Proforma invoice
- Goods description
- Currency and value
- Payment method
- Applicable permits
- Insurance documentation
An incomplete or inconsistent file can be queried rather than approved.
Step 5: Form M Is Reviewed and Registered
After the authorised dealer bank processes the application, it moves through the relevant regulatory and Customs workflow.
Nigeria Customs’ current service standard describes the process as the importer completing Form M through an authorised dealer bank, followed by approval and NCS registration.
Once successfully registered, the Form M becomes part of the electronic record used for subsequent import processes.
What Happens After Form M?
Form M is not the end of the import process.
Once the supplier ships the goods, additional shipping documents become available, including:
- Final commercial invoice
- Packing list
- Bill of Lading or Air Waybill
- Certificate of Origin
- Other required certificates
These documents feed into the next major Customs stage: the Pre-Arrival Assessment Report, or PAAR.
Form M vs PAAR
Form M and PAAR are often confused, but they perform different functions.
Form M records and processes the proposed import transaction before shipment or arrival.
PAAR is a Customs assessment document generated later using the Form M and final shipment information.
The official import procedure directs importers to obtain PAAR through B’Odogwu after Form M and applicable certificates are in place.
You therefore cannot treat PAAR as a replacement for Form M.
The normal sequence is closer to:
Product approvals → Form M → Shipment → PAAR → Customs declaration → Duty payment → Inspection → Release
Some stages may overlap in practice, but the documents remain distinct.
How Long Is Form M Valid?
This is an area where importers should be careful with older online guides.
Nigeria’s Form M validity rules have changed over time, which means old articles may quote outdated periods.
The 2026 Fourth Edition of the CBN Foreign Exchange Manual provides for an initial validity period of 360 days for general merchandise, with an additional 180-day extension available through the authorised dealer bank.
For capital goods, the current framework provides a longer initial period of 720 days, with further extension provisions.
Where an import will take a long time to manufacture or ship, confirm the applicable validity and extension procedure with the authorised dealer bank before relying on the dates.
Common Form M Mistakes
Using an Incorrect HS Code
The wrong classification can affect permits, Customs valuation, duties and PAAR.
Inconsistent Product Descriptions
Avoid describing the goods one way on the proforma invoice and materially differently on later shipping documents.
Wrong Values
The transaction value should be supported by the commercial documents.
Applying Without Required Permits
If your product requires SON, NAFDAC or another regulator’s approval, deal with that requirement early.
Shipping Too Early
Do not tell the supplier to ship simply because you have paid a deposit.
Make sure the required Nigerian pre-import processes have been completed first.
Ignoring Form M Validity
Production delays can push shipments beyond the relevant Form M period. Monitor the validity date and request an extension early where necessary.
Treating Form M as Customs Clearance
An approved Form M does not mean the cargo has cleared Customs.
PAAR, declaration, duty assessment, examination where required and final release still follow.
Final Thoughts
Form M should be treated as part of your import planning, not as paperwork to complete after your goods have shipped.
Start with the correct HS code. Confirm whether the product needs a licence or certificate. Get an accurate proforma invoice and insurance documentation. Then process the Form M through your authorised dealer bank using the current trade system.
After shipment, keep the final invoice, packing list, Bill of Lading and certificates consistent with the information already declared.
Getting Form M right at the beginning makes the later PAAR and Customs process much easier.
A small discrepancy before shipment can often be corrected quickly. The same discrepancy after a container reaches a Nigerian port can become much more expensive.
