AI-Powered supplier vetting

SummaryThe supplier is an ISO9001:2015-certified fastener, machined-component, and associated-products manufacturer with stated certifications including API 20E-0066 BSL2, PED, AD2000 Merkblatt W0, and compliance with multiple international standards. It reports six production lines, six to ten quality-control staff, and annual capacities of 4,000 tons of studbolts, 5,000 tons of hex nuts, 3,000 tons of thread rods, and 4,000 tons of hex bolts. The supplier supports extensive customization, ODM, and OEM services, and reports new products during the past year. Export experience is stated as 15 years, with 90% of sales from exports and broad global markets. However, service and complaint procedures lack written records, and the supplier has no overseas warehouse, showroom, agent, branch, or offline trade-show participation. Financial evidence is insufficient for a credibility judgment.

Supplier typeThe supplier identifies itself as an ISO9001:2015-certified manufacturer of fasteners, machined components, and associated products. Its stated product range includes studbolts, hex nuts, thread rods, and hex bolts, supported by six production lines and dedicated cutting, punching, chamfering, and heat-treatment facilities.

CertificationsThe supplier reports ISO9001:2015 certification and additional certifications including API 20E-0066 BSL2, PED2014/68/EU, and AD2000 Merkblatt W0. It also states compliance with ASTM, ANSI, DIN, ISO, AS, GB, and EN standards, providing explicit evidence of broad certification and standards coverage.

After-Sales capabilityThe supplier has written procedures for service assessment, approved-supplier management, corrective and preventive actions, and complaint handling, but no written records are available for these processes. It also has no overseas warehouse, showroom, agent, branch, or offline trade-show participation, limiting demonstrated overseas service infrastructure.

R&D capabilityThe supplier reports that it introduced new products during the past year, provides ODM services, and has a stated total experience of two years for R&D engineers. It does not have an available SDK, but the reported new-product activity and ODM capability provide some evidence of innovation support.

Production capacityThe supplier reports six production lines, six to ten quality-control staff, and stated annual capacities of 4,000 tons of studbolts, 5,000 tons of hex nuts, 3,000 tons of thread rods, and 4,000 tons of hex bolts. Its facilities include cutting, punching, chamfering, and heat treatment, indicating established manufacturing capability.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. These capabilities are stated consistently across the R&D and production information, supporting a broad customization offering.

Client casesThe supplier states that it provides OEM services for well-known brands, has exported for 15 years, derives 90% of sales from exports, and serves markets across the Americas, Europe, Asia, Africa, Australia, and the Middle East. These statements demonstrate reported customer and market experience, although no specific customer names or project details are provided.
