AI-Powered supplier vetting

SummaryLianyungang Runlai Quartz Technology Co., Ltd. is a limited company and combined supplier offering quartz products, with business activities spanning non-metallic mineral manufacturing, sales, and technology services. It operates two production lines, has two export-trade staff, and reports eight years of export experience, although its primary export market is listed as domestic. The supplier supports customization from samples, designs, and minor modifications, but does not provide 3D software design services and has no available SDK. No supplier management-system certification is reported. Production controls show a stated gap in continuous quantity reconciliation and finished-product inspections are guided by instructions without written records. Financial-capacity indicators are reported for 2023–2025, but the slices do not establish financial strength. Audit information identifies TÜV Rheinland and a report validity period, but no favorable audit outcome is demonstrated.

Supplier typeThe supplier is identified as Lianyungang Runlai Quartz Technology Co., Ltd., a limited company with a combined company type. Its primary product is quartz products, and its stated business scope includes manufacturing and sales of non-metallic mineral products plus technology-related services.

CertificationsThe supplier management-system certification field is explicitly reported as NIL. Although TÜV Rheinland is identified as the audit organization and an audit report validity period is provided, the slices do not identify a held certification or establish a positive audit result.

Production capacityThe supplier operates two production lines and manufactures quartz and other non-metallic mineral products. It has an outsourcing standard operating procedure, but does not continuously reconcile quantities for every batch or mass-production run, and finished-product inspections have instructions without written records.

Customization capabilityThe supplier explicitly supports customization from samples, customization from customer designs, and minor customization. This demonstrates multiple stated customization routes, although 3D software design services are not available.
