AI-Powered supplier vetting

SummaryQuzhou Puda Technology Co., Ltd. is a China-based trading company established in 2025. The available information indicates professional technical supplier capabilities, including 3D software design, multiple forms of customization, technical support, and two R&D engineers. It reports more than 10 national patents, CE, GOST, and ISO 9001 certification, manufacturing-related facilities, and university cooperation. However, quality assurance and traceability status are unknown, quality-control test equipment is recorded as zero, and no overseas showroom, agents, branches, or offline trade-show participation is reported. Financial information is provided only as year labels, without assessable financial results. The supplier states that products are exported to several regions and that exports account for more than 85%, but specific customer cases are not identified.

CertificationsThe supplier states that its products have passed CE, GOST, and ISO 900 certification, and that it possesses more than 10 national patents. These are explicit certification and technical-qualification claims, although the provided information does not include certificate numbers, validity dates, or issuing details.

After-Sales capabilityThe supplier reports 24-hour global remote technical support, three-year warranties for key components, and R&D engineers responsible for production and after-sales technical support. However, complaint handling and corrective/preventive-action mechanisms are listed as “Others,” while overseas agents, branches, showrooms, trade-show participation, and identified overseas service countries are not reported, limiting verification of broader service coverage.

R&D capabilityInnovation-related evidence includes professional technical supplier status, 3D software design services, two R&D engineers, more than 10 national patents, and technical laboratories jointly established with Zhejiang University and Quzhou University. The engineers are described as handling customer-request confirmation, new-product design, and technical support, supporting a positive assessment.

Production capacityThe supplier describes a modern manufacturing base with precision machining centers, automated spraying lines, and complete machine-testing platforms. However, the recorded quantity of quality-control test equipment is zero, and the quality-assurance and traceability statuses are unknown, so production infrastructure is evidenced but quality-control capability is not fully verified.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. Its technology engineers are also responsible for confirming customer requirements and designing new products, providing direct support for the stated customization capability.
