AI-Powered supplier vetting

SummaryThe supplier demonstrates broad customization, OEM/ODM availability, documented quality and service procedures, ISO9001:2015 certification, and substantial stated output for metal shrapnel and springs. It exports to multiple global regions, has self-operated import/export rights, and reports peak and off-season lead times within 15 workdays. However, it operates one production line and lacks overseas warehouses, showrooms, agents or branches, and offline trade-show participation. Financial records are referenced for 2022–2024, but no financial results are provided. Innovation evidence is mixed: ODM and extensive design services are available, while no new product was reported in the past year and no SDK is available.

Supplier typeThe supplier provides OEM services for well-known brands and ODM services, offers self-operated import/export capability, and supports multiple forms of product customization. These attributes indicate a manufacturer capable of both contract production and design-based supply rather than only distribution.

CertificationsThe supplier states that it holds an ISO9001:2015 certificate and describes a strict quality-control system covering the whole production process. The provided evidence supports certification holding, although no additional certifications are identified.

After-Sales capabilityThe supplier has documented procedures and records for service assessment, corrective and preventive actions, and customer complaints. It accepts several quotation and payment terms, but has no overseas warehouse, showroom, overseas agent or branch, and reports zero countries with overseas services, limiting local after-sales coverage.

R&D capabilityThe supplier offers ODM and broad design services, including customization from samples and designs. Conversely, it reported no new product in the past year and no available SDK, so evidence supports design execution more strongly than ongoing product innovation or software capability.

Production capacityThe supplier operates one production line and reports annual output of 6 billion metal shrapnel pieces and 50 million compression, tension and torsion spring pieces, with four quality inspectors. It states lead times within 15 workdays in both peak and off-season periods, but the one-line structure provides limited evidence of production redundancy.

Customization capabilityBoth production and R&D information lists customization from samples, designs, full customization, minor customization and flexible customization. This is explicit evidence of a broad customization range for spring and metal-shrapnel products.
