AI-Powered supplier vetting
SummaryThe supplier is a Tianjin-based manufacturer and engineering/trading provider with two production lines and stated valve output of 18,000 pieces. It reports API6D certification for its products, an ISO9001-based quality management system, and OHSAS/OHSMS 18001 certification. The supplier supports extensive customization, OEM services for recognized brands, and direct export with 51%–70% of sales from exports. Quality procedures, complaint handling, corrective actions, and supplier assessment procedures are documented and followed. However, it has fewer than five quality-control staff, no reported R&D engineer experience, no stock, overseas warehouse, overseas branch, or overseas showroom capabilities, and no SDK availability. Financial credibility cannot be fully assessed from the permitted information because the provided financial records are incomplete and monetary figures are excluded.
Supplier typeThe supplier operates as a manufacturer and engineering/trading provider covering hardware and electrical equipment, pipeline engineering design and construction, wire and cable sales, and import/export activities. Its factory is located in Jinnan District, Tianjin, China, with two production lines and stated valve production output.
CertificationsThe supplier states that its products have API6D certification and that its quality management system follows ISO9001 requirements; it also reports OHSAS/OHSMS 18001 certification for supplier management systems. These are explicit certification or standards-related credentials, although the supplied information does not provide certificate validity dates or scopes in detail.
After-Sales capabilityThe supplier has documented and followed procedures for customer complaints, corrective and preventive actions, quality assurance, and supplier-service assessment. However, it reports no overseas agents or branches, no overseas warehouse, no overseas showroom, no in-stock service capability, and service coverage in zero countries, so international local-service capability is limited.
Production capacityThe supplier operates two production lines and reports valve output of 18,000 pieces, with valid manufacturing contracts covering associated subcontractors and a standard outsourcing procedure. Lead time is stated as within 15 working days in both peak and off-season periods, but the factory lacks stock capability and does not continuously reconcile quantities for each batch or mass production.
Customization capabilityThe supplier explicitly supports customization from samples, designs, full customization, minor customization, and flexible customization. It also reports OEM capability for recognized brands, providing direct evidence of broad product adaptation and OEM service capability.
Client casesThe supplier states that it provides OEM services for recognized brands, and its products reportedly hold API6D certification. These statements indicate experience serving brand customers, but no named customers, project references, order examples, or independently verifiable case details are provided.
