AI-Powered supplier vetting

SummaryThe supplier is identified as a trading company located in Chongqing, with four production lines and stated RO membrane sheet output of 15,000,000 square meters. It supports sample-based, design-based, minor, and full customization and offers ODM services. Export sales account for 31%–40% of total sales, with export terms including FOB, CIF, CFR, and EXW. However, evidence shows weaknesses in documented service execution: procedures for supplier assessment, corrective actions, and complaint handling exist without written records. The supplier has no overseas warehouse, showroom, agent or branch, or offline trade-show participation. Innovation evidence is limited because no new products were reported in the past year and no SDK is available. Quality-control staffing and staff experience are either unavailable or reported as zero. Financial information provided for recent periods consists of zero values, making financial credibility difficult to establish.

Supplier typeThe supplier is explicitly classified as a trading company, located in Chongqing’s Kaizhou District, and associated with the scientific research and technical services industry. This establishes its registered business type but does not by itself confirm whether it owns or directly operates manufacturing facilities.

After-Sales capabilityThe supplier has procedures for service assessment, corrective and preventive actions, and complaint handling, but no written records are maintained for these processes. It has no overseas warehouse, showroom, overseas agent or branch, and offers services in zero overseas countries, limiting demonstrated international after-sales infrastructure.

Financial creditThe supplied financial records report zero operating revenue, operating cost, gross profit, operating profit, gross margin, and current ratio for the stated recent periods. These figures provide no positive evidence of operating financial strength and create a material basis for concern about financial credibility.

R&D capabilityThe supplier offers ODM services and customization through samples and designs, but reports no new products during the past year, no available SDK, and only one year of total R&D engineer experience. This indicates some design-related capability but limited demonstrated recent innovation.

Production capacityThe supplier reports four production lines and annual RO membrane sheet output of 15,000,000 square meters, with off-season lead time within 15 working days and peak-season fulfillment of one month. However, it does not conduct continuous quantity reconciliation for every batch or mass production, and quality-control staffing is unavailable, creating a production-control weakness.

Customization capabilityThe supplier explicitly supports customization from samples, full customization, customization from designs, and minor customization, and also provides ODM services. These stated capabilities directly support a broad range of customer-specific product development requirements.
