AI-Powered supplier vetting

SummaryThe supplier is a combined company with manufacturing, export, service, quality-control, R&D, and sustainability capabilities. It reports ISO9001:2015, ISO45001:2018, ISO14001, ISO50001, and other management-system certifications, plus CE product compliance. Its production facilities cover lead oxide powder, grid casting, pasting, cutting, assembly, charging, and vacuum acid processes for lead-acid and VRLA batteries. The supplier offers flexible customization, 3D software design, ODM, and OEM services, but reports no private mold capability and no available SDK. Service systems include written procedures, records, complaint handling, corrective actions, and traceability. It exports to numerous regions and has 24 years of export experience, although no Fortune 500 cooperation is reported and overseas service-country data is listed as zero. The provided financial entries identify reporting years but do not establish financial strength.

Supplier typeThe supplier is identified as a combined company and provides manufacturing, export trade, service, quality control, R&D, and sustainability functions. Its listed facilities cover multiple battery-production stages, indicating an integrated manufacturing-oriented supplier rather than a purely trading entity.

CertificationsThe supplier reports ISO9001:2015, ISO45001:2018, ISO14001, ISO50001, and other management-system certifications, as well as CE product compliance. These stated certifications provide explicit evidence of certification coverage across quality, occupational safety, environmental, energy, and product compliance areas.

After-Sales capabilityService capability is supported by written procedures and followed records for supplier assessment, corrective and preventive actions, and customer complaints; quality assurance and raw-material traceability are also reported. However, the overseas-service-country field is recorded as zero, so international after-sales coverage is not fully demonstrated.

R&D capabilityThe supplier reports new products within the past year, ODM capability, OEM services for popular brands, 3D software design services, and flexible customization. Conversely, it explicitly reports no available SDK and no private mold capability, so innovation is demonstrated mainly through product and design services rather than proprietary tooling or software integration.

Production capacityProduction infrastructure includes lead oxide powder, grid casting, pasting, cutting, assembly, charging, and vacuum acid facilities, with lead-acid and VRLA batteries listed as annual productivity categories. Finished-product inspection instructions are uniformly followed, and quality control includes assurance and traceability, supporting a documented production capability.

Customization capabilityThe supplier explicitly provides flexible customization and 3D software design services, and its R&D design services are described as flexible customization. However, it reports no private mold capability, indicating customization is available but may not include dedicated proprietary mold development.
