AI-Powered supplier vetting

SummaryThe supplier offers plastic and glass laboratory consumables, including sampling bags, pipettes, swabs, tubes, dishes, slides, and reagent bottles. It reports ISO9001, ISO13485, and CE certifications, Class 100,000 purification workshops, standardized production lines, and quality testing centers. Export activity is substantial, with 90% of sales reportedly from exports, markets in America, Europe, and South America, and exporting since 2010. However, the available evidence shows significant documentation and control gaps: no R&D audit documents, no written CAPA or complaint-handling procedures, zero reported quality-control test equipment, and unknown quality-assurance and traceability status. Financial figures for the stated years are all zero, limiting confidence in financial credibility. The supplier has one R&D engineer, SDK availability, in-stock capability, and reported one-month lead times, but no overseas warehouse, showroom, or popular-brand OEM capability.

Supplier typeThe supplier is presented as a manufacturer and exporter of plastic and glass laboratory consumables, supported by stated standardized production lines, purification workshops, and quality testing centers. Its reported product scope and export activity indicate a laboratory consumables supplier serving international markets.

CertificationsThe supplier explicitly states that its factories hold ISO9001, ISO13485, and CE certifications and that products follow ISO-standard quality control systems. However, the supplied information does not include certificate numbers, validity dates, or audit documentation.

After-Sales capabilityThe supplier claims customer service before and after sales, but it has no written corrective and preventive action procedures or records and no written complaint-handling procedures or records. Its service-capability assessment also lacks written procedures or followed records, so formal after-sales controls are weakly evidenced.

Financial creditThe provided financial records report zero operating revenue, gross profit, operating profit, operating costs, and current ratio values for the stated periods, including the last year and prior multi-year periods. These reported values do not demonstrate financial strength and materially limit confidence in the supplier’s financial credibility.
