AI-Powered supplier vetting

SummaryWenzhou Zhengkai Electric Co., Ltd. is an export-oriented electrical manufacturer with 24 years of export experience and 51%–70% of sales generated from exports. It reports OEM service for well-known brands, broad customization options, automated production equipment, in-stock capability, and lead times within 15 working days in both peak and off-season periods. The supplier holds an ISO9001:2015 management-system certificate and reports CCC-related product certification capability. However, manufacturing capacity is not covered by a valid contract with associated subcontractors, overseas service infrastructure is absent, and after-sales support capabilities are not sufficiently evidenced. Quality inspection is handled by one inspector, with instructions but no written finished-product inspection records. Financial data is inconsistent across the provided records and cannot support a reliable financial assessment.

Supplier typeThe supplier is identified as Wenzhou Zhengkai Electric Co., Ltd. and demonstrates manufacturing and export characteristics: it has exported goods for 24 years, derives 51%–70% of sales from exports, and reports in-stock capability. However, it also relies on associated subcontractors without a valid manufacturing-capacity contract, so the precise extent of fully controlled in-house manufacturing is unclear.

CertificationsThe supplier reports an ISO9001:2015 certificate for its management system and CCC among its product compliance certifications. These are explicit certification indicators, although the slices do not provide certificate scope, validity dates, or copies.

After-Sales capabilityThe supplier has no overseas warehouse, overseas showroom, overseas agents or branches, and offers overseas services in zero countries. These facts indicate limited overseas service infrastructure, while the slices do not provide specific warranty, repair, replacement, or customer-support procedures.

Production capacityProduction resources include automatic welding, winding, riveting, spot-welding, assembly, laser-marking, and pad-printing equipment. The supplier reports in-stock capability and lead times within 15 working days in both peak and off-season periods, but the absence of a valid capacity contract with associated subcontractors and the lack of written inspection records create control limitations.

Customization capabilityThe supplier explicitly supports customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also reports OEM service for well-known brands, providing direct evidence of broad customization and OEM capability.
