In 2023, a gold mining company in the Democratic Republic of Congo had 800 kW worth of generators stranded at Matadi port for 11 weeks. The holdup? A missing SONCAP certificate for Nigeria (their transit country), an expired ISO certificate from the supplier, and no SGS pre-shipment inspection report. Total demurrage charges and production losses exceeded $340,000.
Mining projects in Africa operate under some of the most complex import regulatory environments in the world. Each country has its own certification requirements, enforcement levels vary wildly, and the consequences of non-compliance are severe. At Tesla Power, we have shipped Yuchai China diesel generator set units to mining operations across 15 African countries. Here is exactly what certifications you need, country by country.
The Foundation — Certifications Every Mining Generator Needs
Regardless of destination, these baseline certifications are non-negotiable:
ISO 9001:2015
This is the manufacturer’s quality management system certification. It proves the factory follows documented processes for production, inspection, and corrective action. For mining applications where generator reliability directly impacts production, this is the minimum quality assurance you should accept.
Tesla Power holds current ISO 9001:2015 certification, audited annually. We provide the certificate with every order.
CE Marking
While the EU does not regulate African imports directly, CE marking is widely recognized and often requested by mining companies, EPC contractors, and project financiers as evidence of electrical safety and EMC compliance. Many internationally-funded mining projects (World Bank, AfDB) require CE marking in their procurement specifications.
Factory Test Report
A detailed report documenting the generator’s performance during factory testing — voltage, current, frequency, power factor, fuel consumption, temperature, and noise level at various load points. At Tesla Power, every unit undergoes a minimum 2-hour full-load test with video recording. Learn about our testing protocol.
Country-Specific Requirements for African Mining Imports
Nigeria — SONCAP (Mandatory)
The Standards Organisation of Nigeria Conformity Assessment Programme is the most strictly enforced import certification in West Africa:
- Process: Obtain a Product Certificate (PC) first, then a SONCAP Certificate (SC) for each shipment
- Testing: May require product testing at an accredited laboratory
- Documentation: Commercial invoice, packing list, bill of lading, PC certificate, SC certificate
- Processing time: PC: 5–7 business days; SC: 3–5 business days
- Cost: $300–$800 per certificate depending on product value
- Enforcement: Very strict — shipments without SONCAP are rejected at the port
Tesla Power tip: We initiate the SONCAP process 4 weeks before shipment. The PC is obtained based on our test reports and ISO certification. The SC is issued for each specific shipment. We handle all coordination — our clients just need to provide their Nigerian import details.
Kenya — PVOC / KEBS (Mandatory)
Pre-Verification of Conformity through the Kenya Bureau of Standards:
- Process: Product inspection and testing before shipment, then Certificate of Conformity (CoC) issued
- Inspection: Physical inspection of goods at the factory or a recognized inspection agency (SGS, Intertek, Bureau Veritas)
- Processing time: 7–14 business days
- Cost: $250–$600 per shipment
- Enforcement: Strict — KEBS inspects shipments at Mombasa port
Tanzania — COI / TBS (Mandatory)
Certificate of Inspection through the Tanzania Bureau of Standards:
- Process: Similar to Kenya PVOC — pre-shipment verification
- Processing time: 5–7 business days
- Cost: $200–$500
Uganda — PVoC / UNBS (Mandatory)
- Pre-Verification of Conformity through Uganda National Bureau of Standards
- Similar process to Kenya PVOC
- Processing: 7–10 business days
Ghana — GSA (Mandatory)
Ghana Standards Authority certification:
- Advance Shipment Inspection required
- Processing: 10–15 business days
- Cost: $300–$700
DRC — FCA / OCC (Required for Mining Concessions)
The Democratic Republic of Congo has additional requirements specifically for mining operations:
- Import permit from the Ministry of Mines for equipment entering mining concession areas
- FCA (Fiche de Cotation douanière) — customs valuation document
- Environmental compliance certificate from the DRC environmental agency
- Equipment specifications in French required for customs clearance
Tesla Power tip: For DRC mining projects, we prepare all documentation in French upon request. We also coordinate with local clearing agents recommended by our mining clients to ensure smooth customs processing at Matadi or Dar es Salaam (for transit through Tanzania).
South Africa — NRCS / SABS (Strictly Enforced)
South Africa has the most rigorous electrical equipment standards in Africa:
- NRCS (National Regulator for Compulsory Specifications): Compulsory for electrical equipment
- SABS (South African Bureau of Standards): Product testing and certification
- Processing time: 15–30 business days — start early
- Cost: $500–$1,500
- Enforcement: Very strict — non-compliant equipment is seized
Countries Without Mandatory Pre-Shipment Certification
Several major mining countries do not require specific pre-shipment certification for generators:
- Sierra Leone, Liberia, Guinea: No mandatory pre-shipment certification, but CE/ISO documentation recommended
- Mozambique: Requires CTIID clearance but process is relatively simple
- Ethiopia: No mandatory pre-shipment certification for generator sets
- Zimbabwe: No mandatory certification, but customs may request quality documentation
Emissions Certifications for Mining Operations
Increasingly, African mining regulators and international mining companies require emissions compliance for mining generator compliance:
- China Stage III / IV: Yuchai engines are certified to China Stage III emissions standards. Stage IV available on select models
- EPA Tier 2 / Tier 3: Required by some international mining companies as a corporate standard, even if not legally required by the host country
- IFC/World Bank Environmental Standards: Many bank-funded mining projects require generators meeting IFC emissions guidelines. Stage III compliance typically satisfies these requirements
- Mine-specific environmental management plans: Individual mines may set their own emissions standards as part of their Environmental and Social Impact Assessment (ESIA)

Frequently Asked Questions
Q1: How long before shipment should I start the certification process?
Minimum 4 weeks for West Africa (SONCAP) and 5 weeks for East Africa (PVOC). For DRC mining projects, allow 6 weeks to accommodate import permits and French documentation. Tesla Power initiates the process immediately upon order confirmation.
Q3: Can I use the same certificates for multiple shipments?
SONCAP and PVOC are shipment-specific — you need a new certificate for each shipment. However, the Product Certificate (PC) for SONCAP can be reused for multiple shipments within its validity period (typically 1 year). Country-specific regulations vary — we track this for every client.
Q4: What happens if I ship without the required certificates?
Customs will likely detain the shipment. You will face: (1) demurrage charges ($100–$300 per day), (2) potential shipment return at your expense, (3) possible fines, and (4) project delays. The cost of non-compliance far exceeds the cost of obtaining certificates. Read our general certification guide.
Q5: Does the mining company’s own certification requirements override country regulations?
Both apply. Country regulations are mandatory for import clearance. Mining company requirements (often specified in their procurement policies) are mandatory for contract compliance. The stricter requirement always governs. For example, if the DRC does not require emissions certification but the mining company’s policy requires EPA Tier 3, you need EPA Tier 3.
Q6: Can Tesla Power help with customs clearance at the destination?
We do not directly handle destination customs clearance, but we maintain relationships with experienced freight forwarders and clearing agents in Nigeria, Kenya, Tanzania, Ghana, DRC, and South Africa. We can recommend reliable partners and coordinate documentation handoff. Ask for our recommended agents list.
