AI-Powered supplier vetting

SummaryThe supplier is identified as a professional technical supplier providing 3D software design, ODM, OEM, and sample-based customization services. It reports ISO9001:2015, ISO14001, and CE certification, along with quality assurance procedures, raw-material traceability, documented complaint handling, and 100% finished-product inspection. Production-related evidence includes waterproof-coil production lines, testing equipment, inventory capability, and lead times within 15 working days in both peak and off-peak periods. However, it has no valid manufacturing contract with related subcontractors, no overseas warehouse or showroom, no SDK, no new products reported in the past year, and no overseas-service countries listed. Financial credibility and customer-case evidence are insufficient for a definitive assessment.

Supplier typeThe supplier explicitly identifies itself as a professional technical supplier and provides 3D software design, ODM, and OEM services, including service to popular brands. This supports classification as a technical/design-oriented manufacturer or supplier.

CertificationsThe supplier reports CE product-compliance certification and ISO9001:2015 and ISO14001 management-system certifications. These stated certifications provide explicit evidence of compliance and management-system credentials.

After-Sales capabilityThe supplier describes a documented after-sales service system, has clear complaint-handling procedures with records, and lists debugging, maintenance, repair, training, and equipment installation services. However, it lists zero countries offering overseas services, so the evidence supports after-sales processes but not broad international coverage.

R&D capabilityThe supplier provides 3D design, ODM, and sample-based customization, indicating design and development capability. However, it reported no new products in the past year, no available SDK, and no established AI model for data-driven decision management, limiting evidence of recent or advanced innovation.

Production capacityThe supplier reports waterproof-coil production lines, tensile and asphalt testing equipment, inventory capability, 100% finished-product inspection, two quality inspectors, and lead times within 15 working days in peak and off-peak periods. Nevertheless, it lacks a valid manufacturing contract with related subcontractors; the evidence demonstrates operational capacity but also a stated contractual deficiency.

Customization capabilityCustomization from samples is explicitly offered, supported by 3D software design, ODM services, and OEM services for popular brands. These capabilities directly demonstrate the ability to accommodate customized product requirements.
