Supplier Evaluation Framework: Beyond Price and Promises

Selecting a supplier involves balancing technical capability, service reliability, financial stability, and post-sale support. Prioritizing manufacturers over trading companies is strongly advised—direct factory relationships ensure transparency in quality control, customization options, and warranty enforcement.

Key Due Diligence Steps for Procurement Managers

• Factory Audits: Request virtual tours or third-party inspection reports (e.g., from SGS or Bureau Veritas) to verify production capacity, workforce training, and equipment maintenance protocols.
• Certifications: Confirm compliance with CE, ISO 9001, and relevant environmental standards. These indicate adherence to international safety and quality benchmarks.
• Performance Metrics: Analyze on-time delivery rates (target >90%), reorder rates (a proxy for customer satisfaction), and response times—all critical indicators of operational reliability.

Additionally, evaluate technical specifications against your production requirements:

• Bag dimensions (width, length, gusset size)
• Material compatibility (LDPE, HDPE, biodegradable films)
• Output speed (bags per minute)
• Power consumption and noise levels

Always request test reports for motor efficiency, sealing consistency, and structural durability. Operational validation through a 72-hour continuous run test should be mandatory before final approval.
