AI-Powered supplier vetting

SummaryXi'an Viber Exp & Imp Co., Ltd. is a China-based limited trading company established in 2024 with eight employees and a valid import/export license. It reports OEM service for well-known brands and broad customization options, but has only one R&D engineer and launched no new products in the past year. The supplier has no inventory, overseas warehouse, showroom, overseas agent or branch, and has not participated in offline trade shows. Lead times are stated as within 15 working days in both peak and off-season, while manufacturing-contract status is unknown. Financial records are identified for 2021–2023, but the provided information does not establish financial strength. Certification holdings, after-sales capability, production resources, and customer cases are not sufficiently evidenced.

Supplier typeThe supplier is identified as a trading company and a limited company based in Xi'an, Shaanxi, China, with eight employees. It is not part of a larger company group and has a valid import/export license, indicating trading and export capability rather than confirmed in-house manufacturing.

After-Sales capabilityThe supplier reports no overseas warehouse, showroom, overseas agent or branch, and offers overseas services in zero countries. Although it accepts several payment and quotation terms and states lead times within 15 working days, the evidence does not establish a dedicated after-sales service structure.

R&D capabilityThe supplier has one R&D engineer, no available SDK, and reported no new product launches in the past year. These facts indicate limited demonstrated innovation activity and no SDK support.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization, and also reports OEM service for well-known brands. This provides direct evidence of broad customization and OEM service capability.
