AI-Powered supplier vetting

SummaryJINSHANMEN TECHNOLOGY CO., LTD. is a China-based limited company in Zhejiang, established in 2011, with 268 employees and a manufacturing-related business profile. The supplier offers multiple transformer types and reports more than 10 production lines, 50 quality-control staff, 5 years of R&D-engineer experience, and production information including 5,000 power transformers. ISO9001:2015 and ISO14001:2015 certificates are stated. It exports to South America and Africa, with exports representing 31%–40% of sales, and reports order fulfillment within 15 working days in both peak and off-peak seasons. Evidence supports established transformer production, quality-system certification, and export capability. However, after-sales service, financial credibility, product customization, and specific customer cases are not sufficiently documented. Some company-history and business-type information is inconsistent across the provided records.

Supplier typeThe supplier is identified as JINSHANMEN TECHNOLOGY CO., LTD., a China-based limited company in Zhejiang with 268 employees. Its records describe manufacturing-related activity and transformer production, although one record also labels the company as a trading company, creating a business-type inconsistency.

CertificationsThe supplier explicitly states that it holds ISO9001:2015 and ISO14001:2015 certificates, while another description refers to ISO9001:2000 and quality-control testing. The current ISO9001:2015 and ISO14001:2015 claims provide positive evidence of formal quality and environmental management systems.

R&D capabilityThe supplier reports use of advanced production technology and testing equipment, Germany-based technology for an SC(B) epoxy dry voltage transformer, and an R&D department working on product design and improvement. The stated R&D engineer experience is 5 years, supporting some innovation capability.

Production capacityProduction evidence includes more than 10 production lines, 50 quality-control staff, power-transformer output information of 5,000 units, and reported annual capacity figures for several transformer categories. The supplier also states order fulfillment within 15 working days during both peak and off-peak periods, indicating substantial operational capacity, although the different capacity descriptions are not fully harmonized.
