AI-Powered supplier vetting

SummaryAnhui Sunshine Stationery Co., Ltd. is a limited company with 31 employees, focused on stationery and operating in international markets. It holds an ISO 9001:2015 certificate and reports OEM experience for well-known brands, flexible customization, inventory capacity, and documented procedures for corrective actions, customer complaints, supplier assessment, and service capability. Export sales represent 90% of total sales, and the supplier has participated in the Canton Fair. However, the available information does not confirm current certification validity, raw-material traceability, manufacturing-capacity contracts, or overseas service coverage. The supplier has no overseas warehouse, showroom, agent, or branch, launched no new products last year, and has no available SDK. Financial credibility and customer-case details are insufficiently documented.

Supplier typeThe supplier is identified as Anhui Sunshine Stationery Co., Ltd., a limited company with 31 employees and no stated affiliation with a larger company group. Its primary and offered product scope is stationery.

CertificationsThe supplier reports holding an ISO 9001:2015 certificate. A TUV Rheinland supplier audit record is also provided, but the audit result is coded as 0 and the stated report validity ended on 2025-07-25, so current certification or audit status is not fully established.

After-Sales capabilityThe supplier has documented and followed procedures for corrective and preventive actions and customer complaints, and describes a prompt after-sale service system. Its service assessment procedure also has written procedures and records, supporting a structured service process.

R&D capabilityThe supplier has four R&D engineers and offers customization, but launched no new products in the last year and has no available SDK. These records show some development resources but do not establish strong recent innovation performance.

Production capacityThe supplier reports inventory capacity and lead times within 15 working days in both peak and off-season periods. However, manufacturing-capacity contract status is unknown, and the 31-employee workforce provides only limited evidence about production scale.

Customization capabilityThe supplier explicitly offers flexible customization, minor customization, full customization, and customization from customer designs. It also reports professional OEM production and control experience, including OEM services for well-known brands.

Client casesThe supplier states that its products are widely accepted by professional customers, has a 50%–80% repeat-buyer preference rate, and reports OEM work for well-known brands. However, no named customers, project details, or independently verifiable case studies are provided.
