This guide covers the sequence we follow with our own distributors. It is not legal advice, and rules change — but the order of operations below has been stable for several years.
Start with Form M, before anything ships
Form M is opened by your bank through the Nigeria Single Window platform, and it has to exist before the goods leave China. Not before they arrive: before they leave. A Form M opened after loading means the shipment is treated as unregistered, and regularising it costs more than the freight.
Two fields decide everything downstream: the product description and the value. Whatever you write here has to match the proforma invoice, the packing list and eventually the bill of lading, word for word and figure for figure.
Ask your supplier for the proforma first
Open the Form M from the proforma invoice, not from a quotation or an email thread. We issue a proforma with the exact description, HS code and unit values we will print on the commercial invoice, precisely so the two cannot drift apart.
SONCAP and the SC certificate
Lighting equipment falls under the Standards Organisation of Nigeria Conformity Assessment Programme. In practice this means the factory is inspected or the goods are tested by an accredited agent before shipping, producing a Product Certificate, which your side converts into a SONCAP Certificate.
- The Product Certificate is issued to the manufacturer and covers a model or model family.
- The SONCAP Certificate is issued against a specific shipment and references your Form M number.
- If a model is not on the Product Certificate, it cannot be added later without a new assessment.
This last point is where mixed orders go wrong. Adding four monitors to a container of lights at the last minute looks harmless and is not.
Getting the HS code right
Most LED studio fixtures classify under 9405, and most camera accessories do not. The duty difference is real, and a wrong code discovered at the port is reclassified by customs rather than by you.
| Item | Typical HS heading | Notes |
|---|---|---|
| LED studio and photographic lamps | 9405.40 | Confirm the subheading with your agent |
| Softboxes, reflectors, grids | 9006.99 | Photographic accessories |
| Light stands and tripods | 9620.00 | Monopods, bipods, tripods and similar |
| Field monitors | 8528.52 | Depends on connectivity |
| Wireless microphone systems | 8518.10 | May require NCC type approval |
The document pack that travels with the container
By the time the vessel sails, your agent should hold all of the following, with identical figures across every one of them.
- Commercial invoice, signed and stamped, with unit prices and the Form M number.
- Packing list showing carton count, gross and net weight, and dimensions.
- Bill of lading, with the consignee exactly as registered.
- SONCAP Certificate and the underlying Product Certificate.
- Certificate of origin, plus CE, FCC and RoHS test reports where requested.
- Pre-Arrival Assessment Report, issued once the pack is complete.
Three mistakes that cost the most weeks
Description drift between documents
The Form M says “LED light”, the invoice says “MZ-CL600B bi-colour studio fixture”, the packing list says “lamp”. Each is true; together they trigger a query. We now copy the Form M description verbatim onto every document we issue.
Adding models after the certificate is issued
A late addition of two or three units is the single most common cause of a held container in our experience. If something has to be added, tell us before the pre-shipment inspection is booked, not after.
Under-declaring to save duty
Customs has valuation references for this category. A declared value well under them attracts an uplift, a penalty and an inspection, and the time cost usually exceeds whatever duty was saved.
A realistic timeline
For a 40 ft container leaving Guangzhou for Apapa, budget the following. Air freight for samples compresses the shipping leg to under a week but changes none of the documentation.
