AI-Powered supplier vetting

SummaryXianning TYI Model Technology Company is a China-based high-tech drone supplier focused on R&D, production, sales training, and technical services. Its stated product range covers agricultural, delivery, FPV, VTOL, firefighting, lightshow, and related drones and accessories. Evidence indicates broad customization capability, OEM/ODM project support, documented quality and complaint procedures, product traceability, CE certification, and export experience of 10 years, with exports representing 71%–90% of total sales. The supplier states production capacity of at least 10,000 drone sets per month and offers multiple international trade terms. Limitations include no available SDK, no overseas warehouse, showroom, agent, or branch, and no stated overseas service-country coverage. Financial information is represented only by years, without substantive performance figures.

Supplier typeThe supplier is presented as a high-tech drone manufacturer and service provider, with business activities covering electronic measuring instruments, agricultural machinery, mechanical equipment, and related products. Its stated drone focus, R&D, production, OEM/ODM, training, and technical-service activities support classification as a drone manufacturer and technology-oriented supplier.

CertificationsThe supplier explicitly reports sustainable-development and product certification capability for CE certification. This is direct evidence of holding or supporting CE certification, although no broader certification portfolio is provided.

After-Sales capabilityThe supplier reports written and followed procedures for service-capability assessment, corrective and preventive actions, and customer complaints, supported by records. However, it has no overseas warehouse, showroom, agent, or branch, and the overseas-service-country field is recorded as 0, indicating limited documented overseas service infrastructure.

R&D capabilityThe supplier describes itself as dedicated to drone R&D and states that its R&D department supports OEM and ODM projects, with a history of innovative development. However, it reports no available SDK, so software-development integration capability is not demonstrated.

Production capacityThe supplier states that it has an advanced production line and can produce at least 10,000 drone sets per month, while also reporting documented inspection procedures, 20 qualified service-capability suppliers, and lead times of within 15 workdays off-season and one month during peak season. These statements provide direct evidence of substantial production and operational capacity.

Customization capabilityThe supplier lists customization from samples, designs, full customization, minor customization, and flexible customization. It also confirms OEM service for well-known brands and describes capacity for OEM and ODM projects, indicating broad customization and contract-manufacturing capability.

Client casesThe supplier explicitly states that it provides OEM services for well-known brands and identifies its own-brand quality-control capabilities for TYI and TYIMOTOR. It also participated in the 2024 Shenzhen International Drone Exhibition, but no named customer cases or independently verifiable project examples are provided.
