AI-Powered supplier vetting

SummaryChangzhou Wujin Jiangnan Special Type Screw Co., Ltd. is a China-based manufacturer/factory producing lock bolts and collars, rivets, semi-tubular rivets, CNC machine parts, and non-standard fasteners. The supplier demonstrates broad customization options, export experience since 2004, and participation in an offline trade show. It holds an ISO 9001:2015 certificate and has reported an environmental impact assessment, regular fire drills, and an active TUVRHEINLAND audit record valid from March 19, 2026 to March 18, 2027. However, the provided information states that it has not launched new products in the past year, does not provide ODM services or an SDK, and does not serve well-known brands through OEM. Service supplier-control procedures exist but lack records, signatures, or dates. No overseas warehouse, showroom, agent, or branch is available. Financial information is present for recent years, but the slices do not provide sufficient performance details for a substantive credibility assessment.

Supplier typeThe supplier is explicitly identified as a manufacturer/factory and a limited company located in Changzhou, Jiangsu, China. It is not indicated to be part of a larger company group, which supports classification as an independent manufacturing supplier.

CertificationsThe supplier reports an ISO 9001:2015 certificate and has a TUVRHEINLAND audit record valid from March 19, 2026 through March 18, 2027. It also reports a factory environmental impact assessment, although the provided information does not identify a separate environmental certification.

After-Sales capabilityThe supplier has written procedures for service-capability assessment and corrective/preventive actions, but no records are available, and the approved supplier list lacks signatures or dates. It also has no overseas warehouse, showroom, agent, or branch, although it has participated in an offline trade show; this indicates limited documented and overseas-localized service support.

R&D capabilityThe supplier explicitly reported no new products in the past year, no ODM service, and no available SDK. These statements indicate limited demonstrated recent product-development and software-development capability.

Production capacityThe supplier is a factory offering lock bolts and collars, rivets, semi-tubular rivets, CNC machine parts, and non-standard fasteners. Its products are also identified in the TUVRHEINLAND audit record, supporting that it operates as a relevant manufacturing supplier, although production capacity, equipment, and output volumes are not stated.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. This is direct evidence of broad product customization coverage.
