4. Evaluating OEM and Customization Capabilities
If you plan to launch your own brand, OEM capabilities are essential:
Basic customization: Logo printing on connectors, custom cable lengths (0.3 meters to over 15 meters), cable jacket color options, custom packaging design, private-label instruction sheets and manual inserts, proprietary connector molds, and cable performance optimization (e.g., enhanced shielding)
Estimated Lead Times: Standard products with logos: 7–10 days; Custom packaging: +7 days; New mold development: 15–30 days
Photos of past OEM projects. Factories with experience in branded services typically provide case studies (subject to client permission).
5. Evaluate Lead Times and Production Capacity
Stock products: 3–7 business days
Production orders: 15–30 business days; Peak season (Q4): Add a 10–15-day buffer
Capacity metrics: Number of production lines, daily/weekly output, peak season handling experience, backup suppliers for raw materials
6. Professional manufacturers have systematic quality control:
Incoming inspection: Raw material testing (copper purity, connector specifications)
In-Process Inspection: Automated testing during production
Final Inspection: 100% inspection or AQL sampling (typically 2.5% or 4%)
Pre-Shipment Inspection: Functional testing, visual inspection, packaging inspection
Questions to Ask:
“What is your defect rate?”
“Do you provide pre-shipment inspection reports?”
“What is your policy for handling defective products?”
Best Practice: Request that the supplier provide pre-shipment samples from actual production batches, not just initial samples.
7. Communication and Responsiveness
Your partnership with the supplier will last for months or even years. Assess communication early on:
Positive signs:
Responses within 24 business hours, clear and detailed answers to technical questions, proactive updates on production status, and sales engineers who speak English (rather than just salespeople)
Urging you to place an order quickly without conducting a thorough review
