AI-Powered supplier vetting

SummaryZhengzhou Shanjie District Qianjiaxin New Material Firm is a China-based private limited company described as both a trading company and manufacturer/factory, offering brown aluminium oxide, precoated sand, and zircon sand. It reports corundum productivity of 1,000 tons and lead times of within 15 workdays off-season and one month during peak season. The supplier holds ISO 9001 certification and reports six to ten quality-control staff and six to ten R&D engineers. It also states that it provides multiple forms of customization. However, the available information identifies significant management and sustainability gaps: no approved-supplier list, written corrective-action or complaint-handling procedures, quality assurance, raw-material traceability, environmental impact assessment report, or new products launched during the previous year. Financial information is represented only by reporting years, without substantive performance evidence.

Supplier typeThe supplier is identified as a private limited company in China, with its business type described as both a trading company and manufacturer/factory in one record and as a trading company in another. Its stated scope includes sales of non-metallic minerals, refractory products, casting materials, and related products, indicating a mixed trading and manufacturing-related profile.

CertificationsThe supplier reports ISO 9001 certification, and an SGS audit record covers the supplier from February 25, 2025 through February 24, 2026. However, the audit evaluation result is recorded as 0 without an interpretation, so the available evidence confirms certification and audit documentation but does not establish the audit performance level.

After-Sales capabilityThe supplier explicitly reports no written procedures or records for corrective and preventive actions and no written procedures or records for effective customer complaint handling. Although it describes product tracking and quality control activities, these do not demonstrate an established after-sales service system.

Production capacityThe supplier reports corundum productivity of 1,000 tons, six to ten quality-control staff, and production output information of 1,000 tons of corundum. It also states lead times of within 15 workdays during off-peak periods and one month during peak periods, supporting a stated production and fulfillment capability.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. This is direct evidence of broad customization services.
