AI-Powered supplier vetting

SummaryShanghai Tengri Metal Products Co., Ltd. is identified as the manufacturer of stainless-steel flat head nuts in M5 and M8 specifications. The supplier has documented corrective-action and complaint-handling procedures, quality assurance, inventory capability, written service-assessment procedures, and ERP-based operational management. It holds ISO9001:2015 and RoHS-related evidence and has conducted fire drills. Its service network is limited: it reports no overseas warehouses, showrooms, agents, or branches, and lists zero countries for overseas services. The supplier supports multiple customization modes and reported new products during the past year, but does not provide 3D software design, ODM, SDK, or recognized-brand OEM services. Manufacturing-contract status, detailed capacity, and customer case evidence remain insufficient for a definitive assessment.

Supplier typeThe supplier is identified as SHANGHAI TENGRI METAL PRODUCTS CO., LTD and is named as the manufacturer of stainless-steel flat head nuts in M5 and M8 specifications. This supports classification as a product manufacturer rather than only a trading or service intermediary.

CertificationsThe supplier reports an ISO9001:2015 certificate and RoHS product-certification capability. These are explicit certification-related credentials, although the slices do not provide certificate scope, validity dates, or issuing-body details.

After-Sales capabilityThe supplier has documented corrective/preventive-action and customer-complaint procedures with follow-up records, plus inventory capability and written service-assessment procedures. However, it reports no overseas warehouses, showrooms, agents, or branches, and lists zero countries for overseas services, limiting its overseas after-sales reach.

R&D capabilityThe supplier reports new products during the past year and uses ERP for digital management of production, procurement, quality control, and logistics. Its innovation-related offering is limited by the absence of 3D software design services, ODM services, and an available SDK.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization. It does not provide 3D software design services or ODM services, indicating customization capability without evidence of complete design-development support.
