Supplier Evaluation
A buyer in Nigeria chose a supplier based on low price alone. The silo arrived with poor coating quality and missing components. Installation was delayed 3 months while issues were resolved. That experience taught us: the cheapest bid is often the most expensive in the end.
Evaluation criteria: Experience with similar projects (minimum 5 years). Reference list with contactable clients. Quality certifications (ISO 9001, CE marking). Financial stability for warranty support. Technical capability for design and engineering.
Quality Assurance
Inspection points: Material verification against mill certificates. Dimensional checks during fabrication. Coating inspection (thickness, adhesion, holidays). Weld inspection per code requirements. Final assembly check before shipment.
Third-party inspection: Engage independent inspection agency. Witness critical tests and inspections. Review all quality documentation. Issue inspection release certificate. Cost typically 0.5-1% of order value.
Shipping and Logistics
Shipping methods: Container shipping for small components (fits in 20' or 40' containers). Break bulk for large shell sections. Flat rack for oversized items like platforms. Plan shipping to minimize transshipment.
Packaging protection: Use VCI paper for rust prevention. Secure components for ocean transit. Mark all parts for easy identification. Include packing list in multiple languages. Photograph loading for documentation.
Import and Customs
Required documentation: Commercial invoice with HS codes. Packing list with weights and dimensions. Certificate of origin for duty calculation. Bill of lading or airway bill. Insurance certificate for transit coverage.
Customs clearance: Engage experienced customs broker. Pre-clear documentation before arrival. Have duty payment ready. Inspect goods upon release from customs. Document any damage for insurance claim.
