AI-Powered supplier vetting

SummaryThe supplier is a limited company manufacturing stainless steel seamless pipes, pipe fittings, and related stainless steel products, with two production lines and stated annual output of 23,000 tons. It serves multiple international markets and has export-experienced staff, but lacks overseas warehouses, showrooms, agents or branches, and has not participated in offline trade shows. ISO9001:2015 certification and recent fire-drill activity are reported. The supplier provides OEM and ODM services and supports broad customization, although no new products were developed in the past year and no SDK is available. Quality controls and service-management documentation are limited: finished products are checked by packing staff, while procedures for supplier approval, corrective actions, and complaint handling are not documented. Financial-related records are identified for 2021–2023, but no non-monetary evidence is sufficient to assess financial credibility. No customer cases are explicitly provided.

Supplier typeThe supplier is a limited company engaged in manufacturing, processing, and sales of stainless steel pipes, pipe fittings, and other stainless steel products. Its stated product scope specifically includes stainless steel seamless pipe, and it is not identified as part of a larger company group.

CertificationsThe supplier reports holding an ISO9001:2015 certificate in both its sustainable-development information and management-system certification records. This explicitly supports the presence of a quality management certification.

After-Sales capabilityThe supplier has 56 qualified service-capability suppliers, but reports no written procedures or records for complaint handling, corrective and preventive actions, supplier approval, or service-capability assessment. It also lacks overseas warehouses, showrooms, agents, and branches, limiting documented and local after-sales support evidence.

Production capacityThe supplier operates two production lines and reports stainless steel seamless pipe output of 23,000 tons, with access to Wenzhou, Ningbo, and Shanghai ports. It exports to numerous regions and reports lead times within 15 working days in off-peak periods and one month in peak periods, but it does not continuously reconcile quantities for every batch.

Customization capabilityThe supplier explicitly supports customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also reports OEM and ODM services, providing direct evidence of broad customization capability.
