AI-Powered supplier vetting

SummaryShenzhen Just-Solar Co., Ltd. is identified as a China-based manufacturer/factory operating in Guangdong, with separate production entities described for domestic and overseas business. The supplier reports multiple management-system certifications, 50 quality-control staff, more than 10 production lines, extensive solar-product output, export activity since 2004, and sales coverage across multiple global regions. It states that it provides product design, R&D, manufacturing, shipment arrangement, warranties, after-sales service, and market suggestions. The available information supports strengths in manufacturing scale, export experience, product development, customization, and stated service capabilities. However, financial credibility cannot be assessed because relevant financial information is excluded, and the representative-title record is invalid or unusable.

Supplier typeThe supplier is explicitly classified as a Manufacturer/Factory, with production locations in Shenzhen, Guangdong, China. Its descriptions identify separate production entities for domestic and overseas business, supporting direct manufacturing involvement rather than a purely trading profile.

CertificationsThe supplier lists BSCI, ISO 9000, ISO 9001, ISO 14001, ISO 14000, HSE, GMP, EICC, and QC 080000 as supplier-management-system certifications. The slice does not provide certificate numbers, validity dates, issuing bodies, or scopes, so the assessment is based on the stated holdings only.

After-Sales capabilityThe supplier explicitly states that it provides a warranty period for each product, after-sale service, and reasonable suggestions for solar products and markets. It also describes support across the full shipment process, indicating a stated service capability beyond production.

R&D capabilityThe supplier states that it designs, researches, develops, and manufactures solar products according to customer requirements, and reports total R&D-engineer experience of 31–40 years. These statements support product-development capability, although they do not quantify patents, laboratories, or new-product launches.

Production capacityThe supplier is identified as a factory and reports more than 10 production lines, 50 quality-control staff, and substantial stated output for solar systems, panels, chargers, and lights. It also lists a broad solar-product portfolio and export coverage across multiple regions, supporting significant production breadth and capacity.

Customization capabilityThe supplier explicitly states that it designs, researches, develops, and manufactures solar products according to customer requirements and supplies products in customers' quality classes. This directly supports customization in product design and quality specifications.

Client casesThe supplier lists Shell, Geodrill, Newmont, Tullow, and Heineken as main customers. These named customer references provide explicit evidence of customer cases, although the slices do not include project details, transaction scope, or verification documentation.
