AI-Powered supplier vetting

SummaryThe supplier demonstrates established membrane-product R&D and customization capabilities, including ODM services, sample/design-based customization, and a professional R&D center. It holds RoHS and multiple management-system certifications, including ISO9001:2015, ISO45001:2018, and ISO14001. Production evidence covers UF membrane, nanofiltration membrane, and membrane filament lines, with standardized finished-product inspection procedures. Service evidence shows participation in Vietwater 2024, stated lead times within 15 workdays in both peak and off-season periods, and access to Ningbo and Shanghai ports. However, the supplier reports no overseas warehouse, showroom, agent, or branch, no SDK availability, no Fortune 500 cooperation, and no established AI-based sustainable-development management capability. Financial information is represented only by years, without sufficient evidence to assess financial credibility.

Supplier typeThe supplier is a membrane-material and membrane-product manufacturer with its own R&D center, production lines for UF membranes, nanofiltration membranes, and membrane filaments, and capability to provide ODM and OEM services. This indicates a manufacturer with design and development functions rather than only a trading role.

CertificationsThe supplier reports RoHS product compliance certification and ISO9001:2015, ISO45001:2018, ISO14001, and other management-system certifications. These explicitly documented certifications support compliance and management-system capability.

R&D capabilityThe supplier has a professional R&D center covering material and water-quality testing, equipment development, pilot testing, and technical exchanges; it reports new products during the past year, ODM services, cooperation with well-known R&D institutions, and seven R&D engineers. The lack of an available SDK is a limitation for software-related integration, but the evidence supports product and materials innovation capability.

Production capacityThe supplier reports UF membrane, nanofiltration membrane, and membrane filament production lines, as well as documented and consistently followed finished-product inspection instructions. These records explicitly support manufacturing scope and standardized quality inspection capability.

Customization capabilityThe supplier explicitly provides customization from samples, customization from designs, full customization, minor customization, and flexible customization, with the same design-service capabilities reported across the provided records. This is direct evidence of broad customization coverage.
