AI-Powered supplier vetting

SummaryYUHUAN ZHONGDA BRASS INDUSTRY CO., LTD. is a limited company with a combined business profile, manufacturing valves and plumbing fittings and processing stamping parts. It reports 26 years of international trade experience, four production lines, two experienced export-trade staff, OEM/ODM services, recent new-product development, and flexible customization. ISO9001:2015 certification and documented procedures for supplier assessment, corrective actions, and customer complaints are reported. The supplier has exported to more than 30 countries and regions, but the available data also shows no SDK, overseas warehouse, overseas showroom, overseas agents or branches, offline trade-show participation, and no continuous batch-quantity reconciliation. Financial information is present only as year labels and cannot establish financial strength from the provided evidence.

Supplier typeThe supplier is identified as YUHUAN ZHONGDA BRASS INDUSTRY CO., LTD., a limited company with a combined company type. Its stated business scope covers manufacturing valves and plumbing fittings, stamping-part processing, and import/export of goods and technology; its primary products are valves and fittings.

CertificationsThe supplier reports an ISO9001:2015 certificate and states that products are manufactured in accordance with EN 331-ISO 9001. A TUVRHEINLAND audit record is shown with a report period from 2026-04-13 to 2027-04-12, although the audit result is recorded as 0 and the certification-management field is listed as “Others,” so the exact scope and audit outcome require clarification.

After-Sales capabilityThe supplier reports written and followed procedures for customer complaints, corrective and preventive actions, and supplier-service assessment. However, it reports no overseas warehouse, showroom, overseas agents or branches, and no overseas-service countries, limiting evidence of localized after-sales support.

R&D capabilityThe supplier reports new products during the past year and offers ODM services, indicating active product-development capability. It also reports no available SDK, so software-development support is not available based on the supplied information.

Production capacityThe supplier manufactures valves and fittings and reports four production lines, supporting established manufacturing capability. It has 26 years of international-trade experience, but does not continuously reconcile quantities for each batch or mass-production run, which is a process-control weakness.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization, together with OEM and ODM services. These statements provide direct evidence of broad customization support.

Client casesThe supplier reports providing OEM services to well-known brands and distributing products to more than 30 countries and regions, including Germany, Russia, Spain, Romania, and Argentina. The information does not identify specific customer names or independently verifiable case details.
