AI-Powered supplier vetting

SummaryThe supplier is identified as a Ningbo-based trading company with professional technical capabilities, including 3D software design, ODM, OEM, and multiple customization options. It reports ISO9001 certification and CE and UL approvals for specified valve products. Production information indicates substantial output across valves, air vents, ferrules, and pipe fittings, supported by 6–10 quality-control staff and broad export coverage, with 90% of sales from exports. Service procedures for corrective actions and complaint handling are documented and followed. However, the supplier has no overseas showroom, agents, branches, offline trade-show participation, overseas warehouse, or in-stock service capability. No new products were reported in the past year, no SDK is available, and financial evidence is limited to stated years without performance details.

Supplier typeThe company is explicitly classified as a trading company located in Haishu District, Ningbo, while also identifying itself as a professional technical supplier with R&D capability. This indicates a trading-oriented supplier with technical and design-service functions rather than evidence of a purely manufacturing company.

CertificationsThe company description states that it passed ISO9001 certification and holds CE approval for ball valves and UL approval for bronze ball valves. These certifications and approvals are explicitly reported, although their scope is limited to the products named.

After-Sales capabilityThe supplier has clear procedures and followed records for corrective and preventive actions and customer complaint handling. However, it reports no overseas agents or branches, no overseas showroom, no overseas warehouse, and no in-stock service capability, so documented complaint processes coexist with limited overseas service infrastructure.

Production capacityReported annual output includes 1,230,000 brass valves, 250,000 bronze valves, 235,000 air vents, 250,000 gunmetal ferrules, and 1,870,000 pipe fittings, supported by 6–10 quality-control staff and access to Ningbo and Shanghai ports. Nevertheless, manufacturing-capacity reconciliation, outsourcing procedures, and contracts are all listed as unknown, preventing a complete assessment of capacity controls.

Customization capabilityThe supplier explicitly offers flexible customization, minor customization, customization from samples and designs, and full customization. It also provides ODM and OEM services, directly supporting broad product-design and customization capability.
