AI-Powered supplier vetting

SummaryGranding Technology Co., Ltd. is a China-based Shanghai supplier operating as both a trading company and manufacturer/factory in biometrics, RFID, time attendance, and access-control products. It reports ISO 9001 certification, three production lines, 6–10 R&D engineers, and 6–10 quality-control staff. The supplier states that it serves customers globally, exports 90% of sales, and offers delivery within 15 workdays in both off-peak and peak seasons. Its descriptions emphasize specialized R&D, responsive sales, logistics, service, and international experience, but these claims are not independently substantiated in the provided data. Trade records show three transactions with one Philippine buyer for facial time-attendance and access-control products, all registered in March 2025. Financial strength, customization capability, and broader customer-case depth remain insufficiently evidenced.

Supplier typeThe supplier is identified as a trade company in Shanghai and is also classified as a trading company/manufacturer/factory. Its business covers security and protection and consumer electronics, with products centered on biometrics, RFID, and access control.

CertificationsThe supplier reports holding ISO 9001 certification for its management systems. This is explicit evidence of a quality-management certification, although no certificate number, issuing body, or validity period is provided.

After-Sales capabilityThe supplier describes itself as providing product and service support, excellent service, prompt service, specialized knowledge, responsive sales, and efficient logistics. These statements support an indicated service capability, but no concrete warranty terms, service network, response metrics, or after-sales case evidence is provided.

R&D capabilityThe supplier identifies itself as a biometrics and RFID provider, reports 6–10 R&D engineers, and describes specialized R&D and newly innovated products. These are explicit indicators of innovation resources and activity, though no patents, development results, or independently verified innovations are supplied.

Production capacityThe supplier is classified as a manufacturer/factory and reports three production lines, 6–10 quality-control staff, delivery within 15 workdays in both peak and off-peak periods, and access to Shanghai port. These details indicate established production and fulfillment capability.

Client casesThe supplier states that it has customers worldwide and serves international markets, while trade records document three transactions involving ASCENDER INNOVATION OPC in the Philippines for facial time-attendance and access-control products. The evidence demonstrates at least one identifiable buyer relationship but provides limited case breadth and no performance or repeat-order details.
