AI-Powered supplier vetting

SummaryJiangsu Yawei Electric Group Co., Ltd. is a limited company producing distribution transformers, power transformers, and dry-type transformers, with 1,102 employees, more than 10 production lines, and reported transformer output of 5,000 pieces. It has ISO 9001:2015, CE, Jiangsu measurement certification, and IEC-related product certification evidence. The supplier demonstrates broad customization, ODM and OEM capabilities, recent product development, quality-control procedures, complaint handling, and corrective-action mechanisms. Its products are sold domestically and exported to several countries, but the available data also shows no inventory, overseas warehouses, overseas showrooms, overseas agents or branches, and no valid manufacturing-capacity contract with associated subcontractors. Financial credibility cannot be assessed because only reporting years are provided, without financial results. Customer evidence is limited to OEM service for known brands and export-market coverage.

Supplier typeThe supplier is identified as Jiangsu Yawei Electric Group Co., Ltd., a limited company and part of a larger group. Its stated product scope is distribution transformers, power transformers, and dry-type transformers.

CertificationsThe supplier reports ISO 9001:2015, CE, Jiangsu enterprise measurement certification, and IEC certification for specified transformer and substation products. A BV audit record is also shown with a stated validity period from April 24, 2026 to April 23, 2027, although the audit evaluation result is recorded as 0 without an explanatory interpretation.

R&D capabilityThe supplier reports new products in the past year, ODM services, technical development and technology-transfer activities, and eight years of total R&D-engineer experience. It does not have an available SDK, but SDK availability is not sufficient by itself to negate the broader evidence of product-development capability.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization. It also reports ODM services and OEM services for well-known brands, providing direct evidence of broad customization and contract-manufacturing capability.
