AI-Powered supplier vetting

SummaryNingbo Mianxuan Import & Export Co., Ltd. is identified as a China-based manufacturer/factory in Zhejiang, offering vehicle parts, CNC machining parts, metal stamping, castings, fasteners, and related 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 infrastructure is limited: no in-stock capability, overseas warehouse, or overseas showroom, while service assessment, complaint handling, and corrective-action procedures lack written records. Financial information is limited to year labels without substantive performance values. No customer cases are provided.

Supplier typeThe supplier is explicitly classified as a Manufacturer/Factory and a limited company based in Ningbo, Zhejiang, China. Its stated product scope covers vehicle parts, CNC machining parts, metal stamping, castings, fasteners, plastic parts, and rubber parts, supporting classification as a diversified manufacturing supplier.

CertificationsThe supplier reports holding TS 16949 and ISO 9001 management-system certifications. It also states that each shipment will include an inspection report with a corresponding material certificate, indicating documented quality-related deliverables.

After-Sales capabilityThe supplier reports no in-stock service capability, overseas warehouse, or overseas showroom. It also has no written procedures or records for service assessment, complaint handling, or corrective and preventive actions, while contract status for manufacturing capacity is unknown.

Production capacityThe supplier operates more than 10 production lines, has 6–10 quality-control staff, and offers a broad metal, machining, casting, plastic, rubber, and vehicle-parts scope. It lists Ningbo and Shanghai ports, 21 qualified suppliers for service capability, and a one-month off-season lead time; peak-season lead-time data is inconsistently stated, limiting a complete capacity assessment.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, and minor customization, in addition to ODM services. These options directly support customized product development, although no evidence is provided for SDK-based development or OEM service for popular brands.

Product Q&A

Q:What international standards do you manufacture hex bolts to?

We produce hex bolts to all major global standards under one roof. This includes DIN 931/933, ISO 4014/4017, ANSI/ASME B18.2.1, BS 916, and JIS B1180. We offer both metric and inch series, covering UNC, UNF, and BSW threads. Custom prints are also welcome.

Q:Can you offer surface finishes that meet European automotive ELV and environmental regulations?

Absolutely. Our eco-friendly finishes are a standard offer. We provide trivalent chromium passivation (Cr3+) zinc plating that is fully ELV-, RoHS-, and REACH-compliant. For extreme corrosion protection, we offer zinc-nickel alloy plating (capable of 720+ hours to red rust in salt spray per ASTM B117) and Cr6-free Dacromet/Geomet coatings.

Q:Is your quality management system IATF 16949 certified for automotive production?

Yes, our manufacturing facility is IATF 16949 and ISO 9001 certified. Our entire quality assurance system, from incoming raw material inspection to final shipment, is designed to meet the sub-PPM (defective Parts Per Million) delivery requirements of automotive OEMs and Tier-1 suppliers. We are also ISO 14001 certified for environmental management.

Q:How do you handle quality complaints or a defective product issue?

We take every quality issue seriously with a structured problem-solving approach. Our team will issue an initial containment within 24 hours, followed by a formal 8D Corrective Action Report within 14 business days, which identifies the root cause and implements permanent corrective actions to prevent recurrence. Your trust and line-down prevention are our top priority.
