AI-Powered supplier vetting
SummaryJinjiang Tagong Hardware Forging Manufacturer Co. Ltd. is identified as a Chinese manufacturer/factory producing a broad range of fasteners and related hardware. The supplier reports multiple customization options, ODM services, new product development within the past year, OEM service for well-known brands, six production lines, and overseas warehouse and showroom capabilities. Export activity has lasted three years, with 31%–40% of sales from exports. Service lead time is reported as within 15 working days in both peak and off-season periods. However, the available evidence shows no SDK, no overseas agents or branches, no continuous quantity reconciliation for production batches, and several procedures without written records. Financial information is limited to stated years rather than performance figures, and the audit result is recorded as 0 without an explained evaluation interpretation. Customer cases are not specifically identified.
Supplier typeThe supplier is explicitly identified as a manufacturer/factory and limited company based in Fujian, China, with fasteners and related hardware as its primary product range. Its offering profile covers manufacturing, export, service, quality control, R&D, and sustainability information.
R&D capabilityThe supplier reports that it developed new products during the past year and provides ODM services, supporting active product-development capability. It also reports no available SDK, which limits the evidence for software or SDK-based development but does not negate the stated hardware R&D capability.
Production capacityThe supplier is a manufacturer/factory with six production lines and a broad fastener and hardware product portfolio. However, it does not continuously reconcile quantities for each batch or mass-production run, indicating a documented production-control weakness.
Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also reports ODM capability, providing direct evidence of broad customization support.
