AI-Powered supplier vetting

SummaryTIANYAN demonstrates strong customization, R&D, export, quality-management, and process-management capabilities. It provides ODM and OEM services, reports new products within the past year, and supports multiple customization modes. ISO9001, ISO14001, and ISO45001 management certifications, CE-related product compliance certification, documented quality and complaint procedures, and ERP-based operational management are reported. The supplier has substantial export experience, with exports representing 71%–90% of sales and 27 years of exporting. However, it reports no overseas warehouse, showroom, agent or branch, or offline trade-show participation. Financial information is limited to reporting years rather than performance results, and no cooperation with Fortune 500 companies is reported.

Supplier typeThe supplier operates as a manufacturer with design and development capabilities: it provides ODM services, OEM services for well-known brands, and customization from samples, designs, or full specifications. Its 27 years of export experience and export share of 71%–90% further indicate an established export-oriented manufacturing profile.

CertificationsThe supplier reports ISO9001:2015 and ISO14001:2015 certifications, with ISO45001:2018 also listed in its management-system certifications. It also reports CE and other product compliance certifications, providing explicit evidence of both management and product certification coverage.

After-Sales capabilityThe supplier has documented procedures and records for service capability assessment, corrective and preventive actions, and customer complaint handling. However, it reports no overseas warehouse, showroom, agent or branch, and no overseas service countries, so its local overseas service infrastructure is limited.

R&D capabilityThe supplier reports new products within the past year, six years of total R&D engineer experience, ODM capability, available SDK support, and multiple design-development services. These data explicitly support active product development and innovation capability.

Production capacityProduction-related evidence includes ISO-certified management systems, 6–10 quality-control staff, documented finished-product inspection instructions, written service procedures with records, ERP integration across production, procurement, quality control, and logistics, and a one-month stated lead time in both peak and off-season. These indicators support organized production and quality operations, although production volume and equipment capacity are not provided.

Customization capabilityThe supplier explicitly supports customization from samples, customization from designs, full customization, minor customization, and flexible customization. The same range appears in both R&D design services and general design capability information, providing direct evidence of broad customization coverage.

Client casesThe supplier reports providing OEM services for well-known brands and indicates an 80%–100% repeat-buyer preference range. However, it reports no cooperation with Fortune 500 companies and provides no named customers, project examples, or verifiable case details.
