AI-Powered supplier vetting

SummaryThe supplier manufactures electronic measuring instruments, electronic components, capacitors and related equipment. It reports broad customization and ODM capabilities, new-product development within the past year, OEM service for known brands, and participation in drafting national and industry standards for small fuses. Quality-related evidence includes ISO9001 certification, multiple safety certifications, and compliance with RoHS and REACH. Production support includes listed manufacturing equipment, in-stock capability, and stated lead times within 15 working days in both peak and off-season periods. However, finished-product inspection is performed by packing staff, only two quality inspectors are reported, and there is no valid manufacturing contract with associated subcontractors. The supplier has no overseas warehouse, showroom, agent, branch, or offline trade-show participation. Customer cases are not specifically identified.

Supplier typeThe supplier is a manufacturer and seller of electronic measuring instruments, electronic components, electronic special materials, capacitors, and related production equipment. Its stated scope includes both manufacturing and wholesale activities, indicating a primarily industrial electronics and component supplier profile.

CertificationsThe supplier states that it has passed ISO9001 certification and obtained VDE, CCC, COC, PSE, KC, and TUV safety certifications. It also states compliance with the latest RoHS environmental directive and REACH regulations, providing explicit evidence of certification and regulatory conformity.

After-Sales capabilityThe supplier reports no overseas warehouse, showroom, overseas agent, or overseas branch, and offers overseas services in zero countries. Although it has in-stock capability and accepts FOB, CIF, and EXW quotation terms, the available evidence does not establish a developed after-sales service network.

R&D capabilityThe supplier reports experienced research and development personnel, independent scientific research and innovation capability, a new product within the past year, and ODM services. It also participated in drafting national and industry standards for small fuses; however, no SDK is available, which limits evidence of software-development integration.

Production capacityThe supplier lists winding, laser engraving, assembly, angle-cutting, and taping machines, reports inventory capability, and states average lead times within 15 working days in both peak and off-season. However, it has no valid manufacturing contract with associated subcontractors, so subcontracting continuity is not established.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. These capabilities are reported consistently across the R&D and design-service records, with ODM availability also confirmed.
