AI-Powered supplier vetting

SummaryThe supplier is identified as a factory in Shenyang, with a business scope covering mechanical equipment, metal products, assistive bicycles, scooters, spare parts, tools, electronics, building materials, and technology import/export. It reports 90% export sales, five years of export experience, self-operated import/export rights, OEM and ODM services, and customization from customer designs. Service strengths include participation in an offline trade show, multiple quotation and payment options, and a complaint-handling procedure with records. However, it reports no inventory, overseas warehouse, showroom, agent, or branch capability, and zero countries offering overseas services. Supplier-service assessment lacks written procedures and records for corrective actions. R&D information indicates no new products in the past year, no SDK, and two R&D engineers. Quality-control evidence is incomplete, with zero listed testing equipment and unknown assurance and traceability status. No certification holding or...

Supplier typeThe supplier is explicitly identified as a factory located in Shenyang, while its stated business scope spans mechanical equipment, metal products, mobility products and parts, tools, electronics, building materials, and technology import/export. This supports classification as a manufacturing-oriented, broad-scope industrial supplier.

After-Sales capabilityThe supplier has a clear customer-complaint handling procedure with followed records and reports eight qualified suppliers for service capability. However, it has no in-stock service, overseas warehouse, showroom, overseas agent, or branch capability, and its service-capability assessment and corrective-action records are not documented; overseas service coverage is stated as zero countries.

R&D capabilityThe supplier provides ODM services and has two R&D engineers, but it reports no new products in the past year and no available SDK. These findings show some design-related capability but explicit weakness in recent product innovation and software-development support.

Customization capabilityBoth design-service records state customization from customer designs and minor customization, while the R&D information confirms ODM service availability. This is explicit evidence that the supplier can support at least design-based, minor, and ODM customization.

Product Q&A

Q:Can the battery be customized?

Yes. We are a lithium battery factory in China, support OEM/ODM service.

Q:How long is the delivery time?

If customized, production takes 15 days. If in stock, ships within 3 days. Air/express takes 10-15 days, sea shipping takes 30 days.

Q:Can batteries be connected in series and parallel?
