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.

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.

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.
