AI-Powered supplier vetting

SummaryThe supplier is a limited company with a combined company type and offers a broad range of fasteners, including screws, bolts, nuts, rivets, spacers, standoffs, washers, pins, and custom fasteners. It reports customization from samples and designs, full and minor customization, recent new-product activity, and ODM services. Quality and service processes are documented, including complaint handling and corrective/preventive actions. The supplier holds an ISO 9001:2015 certificate. However, it has no valid manufacturing contract with associated subcontractors, no overseas warehouse, showroom, agents, or branches, and no SDK or famous-brand OEM experience. Export destinations and participation in an Indonesian industrial trade show demonstrate some international market exposure, but customer-specific cases are not identified. Financial credibility cannot be assessed because the provided financial fields contain zero values and no contextual explanation.

Supplier typeThe supplier is identified as a limited company with a combined company type and is not part of a larger company group. Its stated product scope covers multiple fastener categories, including custom fasteners, indicating a focused manufacturing and supply profile.

CertificationsThe supplier reports holding an ISO 9001:2015 certificate. This explicitly supports the presence of a quality-management certification, although the provided information does not identify its certification scope or issuing body.

After-Sales capabilityThe supplier has written procedures and followed records for customer complaint handling, corrective and preventive actions, and service-capability assessment. These documented mechanisms support structured after-sales and issue-resolution capability.

R&D capabilityThe supplier states that it had new products during the past year and provides ODM services, which supports active product-development capability. However, it does not have an available SDK, so the evidence supports product innovation but not software-development integration capability.

Production capacityThe supplier produces fasteners to DIN, ANSI, ISO, GB, and GIS standards, reports in-stock capability, and states average peak- and off-season lead times within 15 working days. However, it has no valid contract with its associated subcontractors, creating a documented weakness in manufacturing-capacity governance.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. Its product scope also includes custom fasteners, providing direct evidence of broad customization capability.
