AI-Powered supplier vetting

SummaryZHEJIANG SOLERAD ENVIRONMENT TECHNOLOGY CO., LTD. is identified as a trading company located in Zhuji, Shaoxing, and registered in April 2025. The supplier reports ISO9001:2015 and ISO14001:2015 certifications, more than 10 production lines, 11–20 quality-control staff, and eight years of combined R&D engineer experience. It offers extensive customization, ODM services, and introduced new products during the past year. However, its service-support infrastructure is limited: it has no overseas warehouse, showroom, agents, branches, or overseas service coverage. Service procedures exist but lack records in several areas, including complaint handling and corrective actions. It has no valid manufacturing-capacity contract with associated subcontractors, does not provide OEM services for popular brands, and has no SDK. Trade evidence is limited to two transactions and one associated buyer name, so customer-case depth is not established.

CertificationsThe supplier reports ISO9001:2015 and ISO14001:2015 certificates, along with other unspecified certifications. These explicitly stated management-system certifications support quality and environmental-management capability.

After-Sales capabilityThe supplier has written procedures for service assessment, corrective/preventive actions, and complaint handling, but no written records for these processes. It also lacks overseas warehouses, showrooms, agents, branches, and overseas service coverage, which limits demonstrated after-sales execution capability.

R&D capabilityThe supplier reports new products during the past year, ODM availability, and eight years of combined R&D engineer experience. However, it has no available SDK; overall innovation capability is supported by product-development evidence, although the scope of technical-platform capability is limited.

Production capacityThe supplier reports more than 10 production lines, 11–20 quality-control staff, multiple manufacturing and testing machines, and standardized finished-product inspection instructions. Nevertheless, it has no valid contract with associated subcontractors for manufacturing capacity, so production resources are evidenced but capacity-continuity arrangements are weaker.

Customization capabilityBoth R&D and general design-service records explicitly list customization from samples, customization from designs, full customization, and minor customization. The supplier also reports ODM service availability, providing direct evidence of broad customization support.

Client casesThe supplier states that it does not provide OEM services for popular brands. The supplied trade record lists one associated buyer name and only two transactions, which does not establish a broad or well-documented customer-case portfolio.
