AI-Powered supplier vetting

SummaryThe supplier is identified as Shanghai Tengri Metal Products Co., Ltd., offering stainless steel flat head nuts in M5 and M8 specifications. It has documented procedures and records for corrective actions, complaint handling, supplier assessment, and service capability. Quality assurance, inventory service, ERP-based process management, ISO9001:2015 certification, RoHS capability, and recent product development are documented. The supplier supports multiple trade and payment terms, reports peak- and off-season lead times within 15 working days to one month, and has participated in Fastener Fair Global 2025. However, no overseas warehouse, showroom, agent, or branch is reported; ODM, 3D design, SDK, and well-known-brand OEM services are unavailable. Manufacturing contract status and customer case evidence are insufficient.

Supplier typeThe supplier is explicitly identified as SHANGHAI TENGRI METAL PRODUCTS CO., LTD and is listed as the manufacturer of stainless steel flat head nuts in M5 and M8 specifications. The available evidence supports classification as a metal-products manufacturer, although its broader supplier type or legal business category is not provided.

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

After-Sales capabilityDocumented procedures and followed records exist for corrective and preventive actions and customer complaint handling. The supplier also has inventory service capacity and supports FOB, CIF, CFR, and EXW quotations, but lacks overseas warehouses, showrooms, agents, and branches; therefore, the evidence supports service-process capability but limited overseas service infrastructure.

R&D capabilityThe supplier reports new products during the past year and maintains several customization-oriented R&D options. It also uses ERP for digital management, but does not provide 3D software design, ODM, or SDK services; the innovation evidence is therefore positive but limited in scope.

Production capacityThe supplier is named as the manufacturer of the listed M5 and M8 stainless steel nuts, reports in-stock service capability, and states lead times of within 15 working days to one month in both peak and off-season periods. Quality assurance and written supplier-assessment procedures are also documented, while the manufacturing-capacity contract status remains unknown.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. The listed products also demonstrate defined variations in size and specifications, although 3D software design and ODM services are unavailable.
