AI-Powered supplier vetting

SummaryNingbo Yinzhou Wenhui Paper Co., Ltd. is identified across the provided records as both a manufacturer/factory and a trading company, specializing in paper, printing, packaging, stationery, toys, and related products. Evidence indicates OEM service for well-known brands, sample-based customization, broad export coverage, and management certifications including BSCI, ISO 14001, and ISO 9001. Production-related information includes a stated workforce of about 500, a 50,000 sqm facility description, 6–10 quality-control staff, and an off-peak lead time of one month. However, the supplier reported no new products launched in the previous year and no available SDK, while raw-material traceability, fire-drill capability, and environmental-assessment status are unknown. Financial records are represented only by years rather than evaluable financial results. The audit record was conducted by BV, but its evaluation result is listed as 0 and the report validity ended in 2024.

Supplier typeThe supplier is recorded as a Manufacturer/Factory and as a Trading Company. Its stated business and product scopes cover paper, printing, packaging, stationery, toys, homeware, and related goods, while the company description identifies it as a paper and packaging manufacturer established in 1995.

CertificationsThe supplier reports BSCI, ISO 14001, and ISO 9001 management-system certifications. A BV audit record exists for the supplier, but the audit evaluation result is listed as 0 and the associated report validity ended on 2024-08-02, so the current status and interpretation of that audit result are not established.

R&D capabilityThe supplier has reported R&D engineer experience of 31–40 years and offers customization from samples. However, it explicitly reports no available SDK and no new products launched in the previous year, indicating limited evidence of recent product innovation and no demonstrated software-development capability.

Production capacityProduction capability is supported by the manufacturer/factory designation, a stated 50,000 sqm facility, about 500 staff, broad product coverage, 6–10 quality-control staff, and a one-month off-peak lead time. The supplier also reports an annual production output category above the stated threshold, although the exact output basis is not further explained.

Customization capabilityThe supplier explicitly provides OEM services for well-known brands and offers customization from samples. These records directly support the ability to produce customized products, although they do not specify minimum order quantities, engineering support, or customization lead times.
