AI-Powered supplier vetting

SummaryThe supplier is identified as a professional technical supplier offering 3D software design, ODM, OEM, and broad customization services. It reports quality-related certification support, including API, ISO, IBR, and SGS certifications, and holds an ISO9001:2015 certificate. Production and service lead times are stated as within 15 working days in both peak and off-peak seasons, with 11–20 quality-control staff and North America as the primary export market. However, the supplier has no available SDK, launched no new products in the past year, has only one year of R&D engineer experience reported, and lacks overseas showrooms, agents or branches, and offline trade-show participation. Environmental assessment documentation, raw-material traceability status, quality assurance status, and several process records are incomplete or unavailable. OEM service for popular brands provides evidence of customer-related experience, but no specific customer names or cases are supplied.

Supplier typeThe supplier explicitly identifies itself as a professional technical supplier and provides 3D software design services. It also offers ODM and OEM services, indicating both technical-service and manufacturing capabilities.

CertificationsThe supplier states that it can provide certifications such as API, ISO, IBR, and SGS according to customer requirements, and specifically reports an ISO9001:2015 certificate. This is explicit evidence of certification-related capability, although no separate certificate details or validity dates are provided.

After-Sales capabilityThe supplier has no overseas showroom, overseas agent or branch, or offline trade-show participation, and reports zero countries with overseas services. It has written procedures for corrective actions and complaint handling, but no written records, so international after-sales coverage and documented execution remain limited.

R&D capabilityThe supplier provides professional technical services, 3D design, ODM, and customization, but reports no available SDK and no new products launched during the past year. Only one year of total R&D engineer experience is stated, while product-information R&D capability is also marked as having no new products, limiting evidence of recent innovation output.

Production capacityThe supplier reports 11–20 quality-control staff, an annual production-output range, and lead times within 15 working days during both peak and off-peak seasons.
