AI-Powered supplier vetting
SummaryThe supplier is a Xiamen-based limited trading company offering fasteners, gaskets, and flanges. It reports annual fastener productivity of 7,500 tons, exports 90% of sales, serves South America, Europe, and North America, and states one-month lead times in both peak and off-peak seasons. Customization from samples is available. However, the supplier reports no available SDK, no new products launched in the past year, no inventory, no overseas agents or branches, no overseas warehouse or showroom, and no offline trade-show participation. Quality and service controls show material gaps: there are no written corrective/preventive-action or complaint-handling procedures, and quality-control test equipment is reported as zero. An ISO 9001:2015 certificate is stated, but financial strength, customer cases, and several traceability and outsourcing controls cannot be adequately assessed from the provided information.
CertificationsThe supplier states that it holds an ISO 9001:2015 certificate. The provided information confirms the stated certification but does not provide certificate validity, scope, issuer, or audit details.
After-Sales capabilityAfter-sales and service infrastructure appears limited: there are no written corrective/preventive-action or customer-complaint procedures or records, no inventory, no overseas warehouse, no overseas showroom, no overseas agents or branches, and no overseas service countries reported. Service assessment has records but no written procedure, and some qualified supplier names were provided.
R&D capabilityThe supplier reports no available SDK and no new products launched during the past year. These explicit statements indicate limited demonstrated innovation capability for the evaluated areas.
Production capacityThe supplier reports fastener productivity of 7,500 tons annually and one-month order lead times in both peak and off-peak seasons, with export markets in South America, Europe, and North America. However, it also reports no in-stock capability, while outsourcing procedures and manufacturing contracts are unknown; the stated output supports capacity, but the overall manufacturing model is not fully validated.
Customization capabilityThe supplier explicitly offers customization from samples. This supports a demonstrated sample-based customization service, although no details are provided on engineering resources, tooling, or development lead times.
