AI-Powered supplier vetting

SummaryShenzhen Jinghai Technology Co., Ltd. is identified as a manufacturer in one record, while another describes the company nature as a trading company. Its stated business covers lithium batteries, heating elements and related heated products, with product-development, structural, electronic, sampling, trial-production and mass-production services. The supplier offers 3D software design and multiple customization modes. Production data states annual battery productivity of 800,000 sets, but finished products are checked by packing staff and only two quality inspectors are reported. RoHS and CE certifications are listed, while no factory environmental impact assessment report is available. The supplier has valid manufacturing contracts with affiliated subcontractors but no in-stock, overseas warehouse or overseas showroom capability. Financial records are referenced for 2021–2023, but no financial results are provided. No SDK is available, and no customer cases are explicitly documented.

CertificationsRoHS and CE are explicitly listed under sustainable development and product certification capability, along with unspecified “Others.” The evidence supports certification capability, but does not identify the additional certifications or provide certification validity details.

R&D capabilityThe supplier is identified as a professional technical supplier, provides 3D software design, and describes product development, structural design and electronic-function development. However, source 1 explicitly states that no SDK is available, limiting evidence of software-platform integration capability.

Production capacityThe supplier describes trial production and mass production, reports annual battery productivity of 800,000 sets, and is identified as a manufacturer with valid contracts covering affiliated subcontractors. Quality oversight is limited in the provided data to two inspectors and finished-product checking by packing staff; no in-stock capability is available.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization and flexible customization. Its stated closed-loop services include product development, structure design, electronic-function development, mold opening, sampling, trial production and mass production, directly supporting broad customization capability.
