AI-Powered supplier vetting

SummaryRomaz demonstrates established R&D and customization capabilities, including ODM services, new-product activity during the past year, and customization from samples, designs, or full requirements. It reports OEM service for well-known brands, quality procedures, traceability for raw materials, CE certification, and an ISO9001:2015 certificate. Export activity represents 31%–40% of total sales, with five years of exporting experience and both agency and self-operated export channels. However, the supplier has no available SDK, overseas warehouse, overseas showroom, overseas agent or branch, and has not participated in offline trade shows. Production scale and customer-specific case evidence are limited in the provided information. Financial records are referenced for multiple years, but the slices do not provide enough non-financial evidence to assess financial credibility.

Supplier typeThe supplier provides ODM and OEM services, maintains product development and sales/service teams, and exports through both agents and its own import-export rights. These characteristics support classification as a manufacturer-oriented supplier with OEM/ODM and export-service capability.

CertificationsThe supplier reports an ISO9001:2015 management-system certificate and CE certification for products or compliance with standards. The slices explicitly document both certifications, although no validity period or certificate scope is provided.

After-Sales capabilityThe supplier has a documented and followed procedure for handling customer complaints, corrective and preventive actions, and service-capability assessment. Its stated service team and quality-assurance procedures further support service capability, but overseas service infrastructure is absent.

R&D capabilityThe supplier reports new-product activity during the past year, ODM services, a product laboratory and development team, and the ability to develop special-project solutions. Its R&D team is described as responding flexibly to market demand, although no SDK is available.

Production capacityEvidence includes a production line, inspection equipment, written and uniformly followed finished-product inspection instructions, one quality-assurance/quality-control inspector, and raw-material traceability. These demonstrate basic controlled production and quality processes, but production capacity or output scale is not provided.

Customization capabilityThe supplier explicitly supports customization from samples, designs, full customization, minor customization, and flexible customization. Its R&D team also provides customized modifications and special-project solutions, indicating broad customization coverage.
