AI-Powered supplier vetting

SummaryThe supplier is identified as a trading company with business activities covering technology services, unmanned aerial vehicle sales, electrical and electronic equipment, software, security and fire equipment, and import/export. It holds ISO 9001 and ISO 14001 certifications and reports ODM and OEM capabilities, including products designed for several DJI drone platforms. Customization is offered from designs and samples, with full, minor, and flexible customization options. Production information indicates tether power system output of 500 pieces, while the supplier reports fewer than five quality-control staff and six to ten years of R&D engineer experience. Service procedures exist for corrective actions and customer complaints, but quality assurance status is unknown. The supplier lacks overseas showrooms, overseas agents or branches, and offline trade-show participation. Financial records are referenced for 2020–2022, but no performance values are provided, so financial credibility cannot be determined.

Supplier typeThe supplier is explicitly classified as a trading company. Its stated scope also includes technology services, equipment and electronic-product sales, software, and import/export activities, indicating a broad commercial and technical business profile rather than a clearly identified manufacturing-only entity.

CertificationsThe supplier reports holding ISO 9001 and ISO 14001 certifications. These are explicit management-system certifications and provide positive evidence for quality and environmental management, although no certification validity dates or scope details are supplied.

After-Sales capabilityThe supplier has documented procedures and records for corrective and preventive actions and customer complaints, and reports lead times within 15 working days in both peak and off-season periods. However, it has no overseas showroom, overseas agent or branch, or offline trade-show participation, and its service-capability assessment procedure lacks a written procedure, limiting evidence of broad overseas support.

R&D capabilityThe supplier explicitly offers ODM services and OEM services for popular brands, reports six to ten years of total R&D engineer experience, and lists tether-station products for multiple DJI platforms. It does not have an available SDK, so innovation capability is supported for product customization and development but not for SDK-based integration.

Production capacityThe supplier reports annual productivity of 500 tether power system pieces and describes products covering multiple tether-station capacities and drone platforms. It also reports fewer than five quality-control staff, while the supplied slices do not establish broader production scale, facility capacity, or manufacturing ownership.

Customization capabilityThe supplier explicitly supports customization from designs, customization from samples, full customization, minor customization, and flexible customization, and also offers ODM services. These statements provide direct evidence of substantial design and customization capability.
