Short answer: SONCAP is not one certificate, it is two. A Product Certificate (PC) is issued to the exporter and covers a product for a defined period; a SONCAP Certificate (SC) is issued for each shipment and is the document customs actually asks for. Circuit breakers sit in Nigeria’s regulated product list, so a consignment without an SC faces a penalty at the port and can be detained. The good news for importers is that no Nigerian certificate holder is needed — the PC can be opened in the exporter’s own name, and the SC relates to the Nigerian importer’s shipment.
We are an independent trading company, not a manufacturer and not an appointed distributor of any brand. Certificates are stated per exact ordering code, never for a whole range. This page covers what a breaker shipment needs, in the order the documents are opened.
The two certificates, and who holds which
| Document | Issued to | Covers | Practical effect |
|---|---|---|---|
| Product Certificate (PC) | The exporter or manufacturer | A product or product family, for a defined validity period | Built once, used for many shipments. This is the part an exporter can own outright. |
| Single-shipment PC | The exporter | One shipment only | Used when a buyer wants a one-off clearance without opening an annual file. |
| Annual / licensed PC | The exporter | Repeated shipments of the same products | The route that suits a repeat order programme; spreads the compliance effort across the year. |
| SONCAP Certificate (SC) | Tied to the Nigerian importer’s shipment | One consignment, against the invoice and packing list | The clearance document. Without it, the goods do not clear normally. |
The naming is the first place buyers trip. The PC is the product-level qualification; the SC is the shipment-level clearance. A supplier waving a PC at you has shown you one half of the chain.
What the Product Certificate actually needs
The PC is built on evidence about the product and the supplier, not on a promise. In practice the file turns on three things:
- A recognised quality management document on the manufacturing side, typically ISO 9001, held by the factory producing the goods.
- An accredited laboratory test report to the relevant IEC standard — IEC 60898-1 for miniature circuit breakers, IEC 61008-1 for RCCBs, IEC 61009-1 for RCBOs, IEC 60947-2 for moulded-case breakers.
- A precise product description: series, code, ratings, poles, curve, and photographs of the unit and its markings that match what will actually be shipped.
That last item is where more shipments fail than anywhere else. The product certificate describes a product; the container contains a product. If the code on the carton does not appear on the certificate, or the label photograph differs from the delivered marking, the SC does not get issued and the goods sit.
Where the SONCAP Certificate sits in the chain
The sequence for a Nigerian import is fixed, and the order matters:
| Step | Who acts | What happens |
|---|---|---|
| 1. Form M | The Nigerian buyer | The import form is opened by the buyer’s bank. The product description on it has to match what will be shipped. |
| 2. Inspection and testing | The appointed inspection company acting for SON | Documents are reviewed, and goods are inspected or sampled according to the route. |
| 3. SONCAP Certificate | Issued per shipment | Names the shipment and the products in it. This is the certificate the port asks for. |
| 4. PAAR and clearance | The importer’s clearing agent | Clearance proceeds against the SC. No SC means the destination inspection route and a penalty. |
Two implications worth planning around. First, the buyer must move early: Form M is the importer’s action, and little proceeds smoothly until it exists. Second, the shipment description is the binding text — the SC is issued against the invoice and packing list, so a late change to models or quantities leaves a document that no longer matches the cargo.
Standards, grid and the product mix that sells
Nigeria runs a 230/400 V, 50 Hz grid, and the conformity framework accepts the IEC breaker standards, adopted as NIS standards. There is no frequency trap on this market: 50/60 Hz IEC devices cover it, and coil-driven products are quoted with a 50 Hz coil as the norm.
| Item | What it means for a Nigerian order |
|---|---|
| MCB standard | Adoption of IEC 60898-1 — the basis for NB1-63, NB1-63H and NXB-63, 1–63 A, 1P–4P, B/C/D curves. |
| Residual current | Adoption of IEC 61008-1 and 61009-1 — NL1-63 RCCB and NXBLE-63 / NB2LE RCBO, 30 / 100 / 300 mA, Type AC and Type A. |
| Moulded case | Adoption of IEC 60947-2 — NM1, NXM and NM8N for distribution boards and incomers. |
| Typical demand profile | Single-phase 1P and 1P+N devices in the 10–63 A band, plus distribution boards and DIN-rail meters. Volume comes from consumer units and small commercial boards. |
| Customs tariff heading | Breakers normally fall under HS 8536.20, which is the heading the regulated-list check keys off. |
Because the market is single-phase heavy, the honest question at quotation stage is not only “which series” but “which 1P+N and RCBO combination”, since the earth-leakage device is often the item that decides whether an installation passes its own inspection.
Failure modes we see on this market
| Symptom | Cause | How to avoid it |
|---|---|---|
| SC not issued | The model shipped is not covered by the PC, or the family was split incorrectly when the PC was opened. | Give the exact codes and quantities before the PC is filed, and keep later shipments inside that list. |
| Goods held at the port | Marking or label photographs on file do not match the delivered units. | Confirm label artwork and carton marks in writing ahead of production. |
| Penalty and destination inspection | The shipment arrives without an SC. | Clear the certificate before dispatch. Penalties are charged against the consignment value and the delay costs more than the certificate. |
| Repeated re-testing | Test reports that do not name the product actually being exported. | Test the code you sell, or use reports whose scope covers that code by name. |
| Timeline slippage | Form M opened late by the buyer while production is already scheduled. | Make the import form a prerequisite of the production slot, not an afterthought. |
What we quote for Nigerian importers
| Role | Series | Notes |
|---|---|---|
| Final-circuit protection | NB1-63, NB1-63H, NXB-63 | 1–63 A, 1P–4P, 6 kA standard and 10 kA on high-breaking versions. |
| Earth leakage | NL1-63, NXBLE-63, NB2LE | 30 / 100 / 300 mA; Type AC and Type A; RCBO combines overcurrent and residual protection in one module. |
| Boards and incomers | NXM, NM1, NM8N; NX2 / DB2 distribution boards | MCCBs to IEC 60947-2, boards from 4 to 36 ways for consumer-unit work. |
| Motor and pump control | NXC, NC1, CJX2 with NR2 relays | IEC 60947-4-1; coil voltage confirmed against the local supply before ordering. |
Public IEC test documentation and certificates exist for several of these series. What we confirm for you, code by code, is what the paperwork covers and what it does not — and we will say so before the order rather than after.
FAQ
Q: Do I need a Nigerian company to hold the SONCAP certificate?
A: No. The Product Certificate can be issued to the exporter or manufacturer. The shipment certificate relates to the importer’s consignment, and the importer opens the Form M. Unlike some markets, there is no requirement for a locally registered certificate holder standing in the exporter’s place.
Q: Is the SONCAP Certificate per shipment or per year?
A: Per shipment. The Product Certificate underneath it can run for a defined period and cover repeat orders, but every consignment needs its own SC before dispatch.
Q: What happens if the goods arrive without an SC?
A: The consignment goes to destination inspection instead of clearing normally, and a penalty based on the consignment value applies. The goods can also be held. It is consistently more expensive than obtaining the certificate before shipment.
Q: Which laboratory report is accepted?
A: Reports from accredited laboratories to the applicable IEC standard — IEC 60898-1 for MCBs, 61008-1 for RCCBs, 61009-1 for RCBOs, 60947-2 for moulded-case breakers. The report must cover the product being shipped, by name.
Q: Does one PC cover several models in a range?
A: It can cover a family, if the family is described accurately when the certificate is opened. The risk is splitting the family wrongly, which is why the exact codes and quantities should be settled before filing rather than after.
Q: Is 50 Hz or 60 Hz the issue for Nigeria?
A: It is not an issue. Nigeria is 230/400 V at 50 Hz, and standard IEC 50/60 Hz breakers suit it. Frequency only needs special attention for coil-driven devices, where the coil is ordered to match the grid.
