AI-Powered supplier vetting

SummaryThe supplier is identified as a factory and limited company in Shenyang, with five employees and a wholesale and retail industry classification. It holds a valid import and export license, has 16 years of export experience, and offers multiple trade terms. Customization services are available, including customization from designs and samples, while OEM services for well-known brands are reported. However, the supplier reports no new products in the past year, no ODM service, no SDK availability, and no overseas warehouses, showrooms, agents, branches, or offline trade-show participation. Service-management documentation is incomplete: procedures for assessment exist, but there are no approved-supplier lists, corrective/preventive-action procedures, or written complaint-handling procedures. Certification holdings, production scale, financial credibility, and customer cases are not sufficiently evidenced. No financial figures are included.

Its stated industry classification is wholesale and retail, while its business scope includes building ceramics, fertilizers, daily goods, chemicals, disinfectants, machinery, and office products.

After-Sales capabilityThe supplier has written procedures and records for assessing service capability and reports a one-month average lead time in both peak and off-season periods.
