AI-Powered supplier vetting

SummaryShenzhen Niteray Industry Limited is identified as a Chinese limited company operating as both a trading company and manufacturer/factory, with five employees and a valid import/export license. It reports professional technical R&D capability, 3D design, ODM, OEM for popular brands, new product launches, and broad customization services. However, its R&D team consists of one engineer, no SDK is available, and production data is incomplete. Inventory capability and an off-season lead time within 15 workdays are reported. Service and quality-control documentation is weak: complaint procedures lack written records, supplier-service assessment and corrective-action procedures are undocumented, and quality-test equipment is recorded as zero. No overseas warehouse, showroom, agent, or branch capability is reported. Sustainability evidence is also limited, with no recent regular fire drills and no factory environmental impact assessment report.

Supplier typeThe supplier is a limited company based in Guangdong, China, operating as both a trading company and manufacturer/factory. It has five employees, no stated parent-group affiliation, and a valid import/export license, indicating an independently operated supplier with formal export authorization.

R&D capabilityThe supplier is identified as a professional technical supplier with 3D design, ODM, and OEM capabilities, and it launched new products during the past year. Its R&D team has one engineer and no SDK is available, so innovation capability is demonstrated but appears limited in scale and SDK support.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization, together with 3D software design and ODM services. These statements provide direct evidence of broad customization capability.

Client casesThe supplier states that it provides OEM services for popular brands, which indicates experience serving recognized-brand customers. No customer names, project details, product examples, or verifiable case records are provided, so the depth of its customer-case evidence is limited.
