AI-Powered supplier vetting
SummaryNingbo Mianxuan Import & Export Co., Ltd. is identified as a China-based manufacturer/factory offering vehicle parts, CNC machining, stamping, casting, die-casting, fasteners, plastic, and rubber products. It reports TS 16949 and ISO 9001 certifications, more than 10 production lines, 6–10 quality-control staff, and shipment inspection reports with material certificates. The supplier provides 3D software design, ODM, and several customization options, but reports no new products in the past year, no SDK, and no OEM service for popular brands. Service-management documentation is weak: no written procedures or records are reported for assessments, corrective actions, or complaint handling. It has no in-stock capability, overseas warehouse, or overseas showroom. Financial records are indicated for 2023–2025, but their results are not provided, so financial credibility cannot be determined. No customer cases are supplied.
Supplier typeThe supplier is explicitly identified as a manufacturer/factory and limited company in Ningbo, Zhejiang, China. Its stated scope covers fasteners, metal products, machinery, vehicle parts, CNC machining, stamping, casting, die-casting, plastic, and rubber parts, indicating broad manufacturing and industrial-product coverage.
CertificationsThe supplier reports holding TS 16949 and ISO 9001 management-system certifications. It also states that each shipment will include an effective inspection report and corresponding material certificate, providing explicit evidence of documented quality-related controls.
After-Sales capabilityThe supplier reports no written procedures or records for service-capability assessment, corrective and preventive actions, or effective customer-complaint handling. It also lacks in-stock service, overseas warehouse, and overseas showroom capabilities, indicating a documented weakness in after-sales and service infrastructure.
Production capacityThe supplier reports more than 10 production lines, 6–10 quality-control staff, and a product range spanning vehicle parts, CNC machining, stamping, casting, die-casting, fasteners, plastic, and rubber parts. It is located near Ningbo and Shanghai ports and reports 21 qualified suppliers, but has no inventory capability and peak-season lead-time data is inconsistent or unclear.
Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, 3D software design services, and ODM services. These statements provide direct evidence of broad product and design customization capability.
