AI-Powered supplier vetting

SummaryPermanent Steel Manufacturing Co., Ltd. is identified as a China-based manufacturer/factory producing steel pipes and fittings, with production bases in Shandong and Tianjin and headquarters in Hunan. The supplier has self-operated import and export rights, eight years of export experience, and exports representing 71%–90% of total sales. It offers customization from samples and reports in-stock service capacity, but lacks overseas warehouses, showrooms, agents or branches, and has not participated in offline trade shows. Service governance is weakly documented: no written supplier-service assessment procedures or approved supplier list are reported. R&D-related capabilities are limited, with no ODM, SDK, or OEM service for popular brands. ERP, OA, CRM, and SAP-based digital management are not established. Certification evidence, financial credibility evidence, and customer case evidence are insufficient.

Supplier typeThe supplier is explicitly identified as a manufacturer/factory and a limited company. Its stated business focuses on steel pipes and fittings, while its business scope also includes marine equipment, components, supporting services, and import/export activities.

After-Sales capabilityThe supplier reports in-stock service capacity and accepts multiple quotation terms, including FOB, CIF, CFR, and EXW. However, it has no overseas warehouse, showroom, agent, or branch, serves zero stated overseas countries through such coverage, and has no written service-capability assessment procedures or approved supplier list, indicating limited documented service infrastructure.

R&D capabilityThe supplier can customize products from samples, but explicitly does not provide ODM services, popular-brand OEM services, or an available SDK. It also lacks ERP integration and reports zero use of OA, CRM, and SAP systems, providing no evidence of strong product-development or digital innovation capability.

Production capacityThe supplier is a steel pipe and fittings factory with production bases in Shandong and Tianjin, 30 employees, in-stock service capacity, and stated one-month average lead times in both peak and off-season. It also has 50 qualified suppliers for service capability, although no written assessment procedure or approved supplier list is maintained.

Customization capabilityThe supplier explicitly offers customization from samples, and its company description states that it provides customized products and services. This is direct evidence of sample-based customization capability, though it does not establish broader design or ODM capability.
