AI-Powered supplier vetting

SummaryWenzhou SanLo is a China-based limited trading company with manufacturer/factory classification and an identified production base in Zhejiang. Its business covers valves, pipe fittings, mechanical seals, and related industrial products, with stated export activity since 2014 and 90% of sales from exports. ISO 9000 and ISO 9001 certifications are reported, alongside three production lines, 6–10 quality-control staff, 6–10 years of R&D-engineer experience, and stated pump-seal output of 2,500,000 sets. The supplier claims product development, testing, logistics, quality-focused service, and cooperation with domestic manufacturers. However, evidence for after-sales procedures, customization execution, and a substantial customer track record is limited. One trade record identifies a buyer and one transaction, but this is insufficient to establish broad customer experience.
