AI-Powered supplier vetting

SummaryQuanzhou Jianeng Building Materials Co., Ltd. is a China-based trading company established in 2015, with three employees and a Fujian address. Its stated product scope covers multiple stone materials for construction and decoration, and it reports CE and SGS certification and exports to more than 100 countries. The supplier offers 3D software design, flexible customization, ODM, and OEM services, but reports no professional technical R&D capability, zero R&D engineer experience, no new products in the past year, and no SDK. Production-related evidence is mixed: six production lines are reported, but the company is classified as a trading company and has no in-stock, overseas warehouse, or overseas showroom capability. Peak-season lead time is one month and off-season lead time is within 15 working days. Financial records are referenced for 2022–2024, but their results are not provided. Customer-specific cases are not identified.

CertificationsThe supplier states that its products have passed CE and SGS certification. This is explicit evidence of certification claims for its products, although the specific products, certificate details, and validity periods are not provided.

After-Sales capabilityThe supplier reports lead times of one month during peak season and within 15 working days during the off-season. However, it has no written service-capability assessment procedures, no approved-supplier list, no corrective and preventive action records, no in-stock service capability, and no overseas warehouse or showroom capability.

R&D capabilityThe supplier reports no professional technical R&D capability, zero total experience for R&D engineers, no new products during the past year, and no available SDK. Although ODM and OEM services are offered, the evidence indicates limited documented in-house innovation capability.

Customization capabilityThe supplier explicitly provides 3D software design services, flexible customization, ODM services, and OEM services for popular brands. These stated offerings support a positive assessment of customization capability, although no examples or technical scope of customized projects are provided.
