AI-Powered supplier vetting

SummaryShenzhen D-King Photoelectric Technology Co., Ltd. is a China-based combined business entity established in 2013, with 24 employees and operations in Guangdong. It supplies multiple LED display categories and states that its products have obtained FCC, RoHS, CCC, CE, ISO, PSE and CQC certifications and are exported to more than 60 countries and regions. The supplier describes structured management, production controls, R&D, testing and after-sales processes, supported by a modern factory exceeding 8,000 square meters and imported automation equipment. However, the supplier-management-system certification field is recorded as NIL, the audit evaluation result is recorded as 0, and several capabilities—including overseas services, R&D service types, OEM/ODM, customer cases and raw-material traceability—are undocumented or unknown. The available information supports strengths in product certification claims, production infrastructure and export reach, but does not establish financial credibility,...

Supplier typeThe supplier is identified as a combined business entity, Shenzhen D-King Photoelectric Technology Co., Ltd., established in China in 2013. Its listed products cover indoor, outdoor, rental, flexible, transparent, sports and interactive-floor LED displays, indicating a specialized LED-display supplier rather than a general trading entity.

CertificationsThe supplier states that its products have passed testing by authoritative organizations and obtained FCC, RoHS, CCC, CE, ISO, PSE and CQC certifications. However, supplier-management-system certification is recorded as NIL, and the audit evaluation result is recorded as 0; therefore, product-level certification claims are explicit, while management-system certification is not established.

After-Sales capabilityThe supplier describes a management system covering shipment, after-sales service and quality analysis, and states that it has a complete R&D, manufacturing, sales and service system. These descriptions support the existence of an after-sales process, but no specific response standards, service locations, staffing or performance evidence is provided.

Production capacityThe supplier states that it operates a modern clean factory exceeding 8,000 square meters, uses imported automation equipment, and applies controls from material selection through mass production. Its management description also covers procurement, production scheduling, process management, shipment and quality analysis, supporting a documented production infrastructure.
