AI-Powered supplier vetting

SummarySuzhou Tsingri Fasteners Co., Ltd. is a China-based limited trading company established in 2023 with 13 employees and a broad fastener portfolio. It reports export activity, self-operated import/export rights, inventory capability, customization from designs and samples, and OEM service for well-known brands. Its stated product output includes multiple screw categories, while lead time during off-peak seasons is within 15 working days. However, quality-control evidence is weak: it reports fewer than five quality-control staff, no quality-testing equipment, unknown quality-assurance and traceability status, and no written procedures or records for corrective actions or complaints. An SGS audit is documented, but the reported evaluation result is 0 and the report expired in 2025. Financial records are referenced for 2021–2023, but no substantive financial assessment is provided. No SDK is available, and no overseas warehouse or showroom is provided.

CertificationsAn SGS audit was conducted, with a report period from May 14, 2024 to May 13, 2025, but the audit evaluation result is recorded as 0. The slices do not identify any active product or management certifications, and the audit report has expired.

After-Sales capabilityThe supplier states that customer emails are handled within 24 hours and that experienced engineers support service coordination. However, it has no written procedures or records for complaint handling or corrective and preventive actions, and it has no overseas warehouse or showroom, so formal and local after-sales infrastructure is not demonstrated.

Production capacityThe supplier reports output across self-drilling, roofing, bi-metal, and self-tapping screws, inventory capability, a 5,000-square-meter manufacturing area, a 3,000-square-meter warehouse, and 500 tons per month capacity, with off-peak lead time within 15 working days. These statements support operational capacity, although the supplier is also classified as a trading company and its manufacturing-capacity contract status is unknown.

Customization capabilityThe supplier explicitly reports customization from designs, samples, full customization, minor customization, and flexible customization. It also states that it provides OEM services for well-known brands, directly supporting broad customization and OEM capability.
