AI-Powered supplier vetting

SummaryThe supplier is identified as a factory in Wujin District, Changzhou, operating in the power, energy, and utility-related sector. It reports ISO9001:2015, ISO45001:2018, ISO14001, and CE certifications. The supplier provides broad customization, ODM, and OEM services, with new products reportedly developed in the past year and six R&D engineers. It has documented procedures for finished-product inspection, supplier management, corrective actions, and customer complaints. Export activity has continued for seven years, with 51%–70% of sales from exports, and it offers overseas warehouse services. Evidence also indicates cooperation with Fortune 500 companies and a repeat-buyer proportion of 80%–100%. Financial records are identified for 2020–2022, but the provided slices do not establish financial strength.

Supplier typeThe supplier is explicitly described as a factory located in Wujin District, Changzhou. Its stated business scope includes battery manufacturing, battery-parts production, battery sales, energy-storage technology services, and related power equipment activities, indicating a manufacturing-oriented energy and power supplier.

CertificationsThe supplier reports ISO9001:2015, ISO45001:2018, ISO14001, and CE certification. These certifications directly support the presence of documented quality, occupational safety, environmental, and product-compliance credentials.

After-Sales capabilityThe supplier has documented and followed procedures for handling customer complaints, including corrective and preventive actions. It also provides overseas warehouse services, but reports no overseas showroom and no overseas agents or branches; therefore, complaint handling and some overseas support are evidenced, while broader after-sales coverage is limited.

R&D capabilityThe supplier reports new products within the past year, ODM capability, and six R&D engineers. It also reports no available SDK, which limits evidence of software-development support, but the available information explicitly supports product R&D and design capability.

Production capacityThe supplier is a factory with battery and related energy-sector manufacturing activities. It has uniformly followed finished-product inspection instructions, documented supplier-management and corrective-action procedures, and reports one-month average lead times in both peak and off-season periods; production scale and capacity volume are not stated.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. The same broad design-service capability is reported in two slices, providing direct evidence of extensive customization support.

Client casesThe supplier reports OEM service for well-known brands and cooperation with Fortune 500 companies. It has participated in The Smarter E Europe trade show and maintains an overseas warehouse, although no specific customer names, project details, or independently verifiable case outcomes are provided.
