AI-Powered supplier vetting

SummaryTIANYAN demonstrates broad customization, ODM, recent product development, and OEM experience for well-known brands. It reports CE product compliance certification and ISO9001:2015, ISO45001:2018, and ISO14001 management certifications. Export experience is substantial, with 26 years of exporting and 71%–90% of sales from exports, supported by self-operated import/export rights and multiple quotation and payment terms. Quality and service procedures are documented, including finished-product inspection, corrective actions, complaint handling, and supplier assessment. However, the supplier reports no inventory capacity, overseas warehouse, overseas showroom, overseas agents or branches, or offline trade-show participation. It also lacks an SDK, has no Fortune 500 cooperation, and provides insufficient evidence to verify financial strength or production capacity.

Supplier typeThe supplier presents itself as a manufacturer and service provider with ODM, OEM, and broad customization capabilities. It has self-operated import/export rights and long export experience, but reports no valid manufacturing-capacity contract with related subcontractors and no overseas service infrastructure.

CertificationsThe supplier reports CE certification for product compliance and ISO9001:2015, ISO45001:2018, and ISO14001 management-system certifications. These stated certifications provide explicit evidence of certification holding, although no certificate scope or validity details are provided.

After-Sales capabilityDocumented procedures exist for customer complaints, corrective and preventive actions, supplier assessment, and service capability management. However, the supplier reports no overseas agents or branches, overseas warehouse, overseas showroom, or overseas-service coverage, which limits evidence of localized after-sales support.

R&D capabilityThe supplier reports new products during the past year, provides ODM and multiple forms of design customization, and uses an ERP system for digitalized production, procurement, quality-control, and logistics management. It does not have an available SDK, while CRM and SAP system adoption are recorded as zero.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also reports ODM availability and new-product development during the past year, providing strong evidence of broad customization capability.

Client casesThe supplier states that it has provided OEM services for well-known brands and has received appreciation from most agents and customers. However, it reports no cooperation with Fortune 500 companies and provides no named customer cases or verifiable project details.
