AI-Powered supplier vetting

SummaryHuona (Shanghai) New Material Co., Ltd. is identified as a private manufacturer/factory in China, operating from Shanghai, with production facilities in Xuzhou. It reports multiple management-system certifications, including ISO 9001, ISO 14001, ISO 9000, ISO 14000, and QC 080000. The supplier demonstrates documented service, complaint-handling, corrective-action, quality-assurance, and material-traceability procedures. It offers customization, ODM, and OEM services, including OEM for well-known brands, but has no SDK and reported no new products in the past year. Production information includes three or five production lines in different records and stated product outputs for heating resistance wire, thermal spray wire, and magnesium alloy. Overseas support is limited to North America debugging, with no overseas warehouse, showroom, agent, branch, or offline trade-show participation reported. Financial evidence is insufficient for assessment because the provided entries identify years rather than...

Supplier typeThe supplier is explicitly classified as a Manufacturer/Factory, privately owned, and based in China, with its operating province and address in Shanghai. This directly supports its status as a manufacturing supplier rather than only a trading or service entity.

CertificationsThe supplier reports ISO 9000, ISO 14001, ISO 9001, ISO 14000, and QC 080000 certifications under its management-system certification information. These stated certifications provide explicit evidence of formal quality, environmental, and related management-system coverage.

After-Sales capabilityThe supplier has written and followed procedures for service capability, corrective and preventive actions, and customer complaints, and reports quality assurance and material traceability. However, overseas support is limited to North America debugging, with no overseas warehouse, showroom, agent, branch, or offline trade-show participation.

R&D capabilityThe supplier reports six to ten years of R&D engineer experience and offers ODM services, but states that no new product was introduced in the past year and that no SDK is available. The evidence shows some R&D resources but also explicit limitations in recent product development and SDK support.

Production capacityThe supplier reports three production lines in one record and five in another, along with stated output quantities for heating resistance wire, thermal spray wire, and magnesium alloy. It also has five experienced export-trade staff, but does not continuously reconcile quantities for each batch or batch production, indicating a documented production-control limitation.

Customization capabilityThe supplier explicitly provides customization from designs, ODM services, and OEM services for well-known brands. These statements directly demonstrate the ability to support customer-specific and branded manufacturing requirements.
