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.

CertificationsThe supplier reports holding ISO 9000 and ISO 9001 management-system certifications. These are explicit certifications relevant to quality-management processes.

R&D capabilityThe company states that it integrates research, development, and testing, and reports 6–10 years of total R&D-engineer experience. These support the existence of development capability, although no specific innovations, patents, or completed development projects are identified.

Production capacityThe supplier reports its own production base, three production lines, 6–10 quality-control staff, and pump-seal output of 2,500,000 sets. It also reports annual productivity for pump seals, providing explicit evidence of manufacturing capacity in this product area.
