AI-Powered supplier vetting

SummaryThe supplier is identified as Zhejiang Leiertai Protection Technology Co., Ltd., a manufacturer and developer of lightning protection and surge protection products. It reports automated filling, dispensing, soldering, and laser-marking equipment, customization from samples and designs, inventory capability, valid manufacturing contracts with related subcontractors, and quality assurance. However, finished-product inspection is performed by packing staff, with two quality inspectors reported, and there is no raw-material traceability identification. The supplier lacks written procedures for corrective and preventive actions, complaint handling, supplier assessment, and approved-supplier-list maintenance. It has no overseas warehouse, showroom, agents, branches, or overseas service countries, and began exporting one year ago. No certifications, customer cases, or documented environmental and fire-safety evidence are provided.

Supplier typeThe supplier is described as a research, development, design, production, and sales enterprise specializing in lightning protection products, including surge protective devices and lightning protection boxes. Its cooperation with construction qualification units also indicates involvement in product development, installation, and technical cooperation.

After-Sales capabilityThe supplier reports no written procedures or records for customer complaint handling or corrective and preventive actions. It also has no overseas agents or branches and offers services in zero stated countries, indicating limited documented after-sales infrastructure, although the slices do not explicitly state that after-sales service is entirely unavailable.

R&D capabilityThe company states that it conducts research and development, design, and continuous development of new lightning protection products, and it has technical cooperation for product development and installation. However, it reports no available SDK, so innovation is evidenced mainly through product R&D rather than software-development support.

Production capacityProduction resources include automatic filling, dispensing, soldering, and laser-marking equipment, valid manufacturing contracts with associated subcontractors, inventory capability, and stated lead times within 15 working days in both peak and off-seasons. Quality-control weaknesses remain: only two quality inspectors are reported, finished products are checked by packing staff, and raw-material traceability identification is absent.

Customization capabilityThe supplier explicitly reports customization from samples, customization from designs, full customization, flexible customization, and minor customization. This provides direct evidence of broad customization coverage.
