AI-Powered supplier vetting

SummaryNingbo Yinzhou Plumbing Hardware Co., Ltd. is a China-based manufacturer/factory in Ningbo, Zhejiang, producing brass and bronze plumbing hardware. It reports substantial annual output across brass ball valves, brass fittings, lead-free brass products, bronze products, and brass bibcocks, exports 90% of sales, and has 16 years of export experience. The supplier supports sample-based customization, ODM, and OEM services, and reported new products within the past year. ISO9001:2015 certification is stated. However, service procedures lack documented records, and the supplier has no overseas warehouse, showroom, agents or branches, or offline trade-show participation. Financial evidence is limited to year labels without substantive financial results, while customer cases are not provided.

Supplier typeThe supplier is explicitly identified as a Manufacturer/Factory and a limited company located in Ningbo, Zhejiang, China. Its reported product-specific output indicates direct manufacturing activity rather than only trading or distribution.

CertificationsThe supplier reports an ISO9001:2015 management-system certificate. Product compliance certification is listed only as “Others,” so the evidence supports management certification but does not identify specific product-standard certifications.

R&D capabilityThe supplier reported new products during the past year and provides ODM services. However, it explicitly reports no available SDK, which limits the evidence of broader R&D or technical-development capability.

Production capacityReported capacity includes 150 tons of lead-free brass products, 50 tons of bronze products, 1,500,000 brass fittings, 300,000 brass bibcocks, and 1,000,000 brass ball-valve sets annually. The supplier exports to multiple global regions, has one-month peak and off-season lead times, and is located near Ningbo and Shanghai ports.

Customization capabilityThe supplier explicitly offers customization from samples, ODM services, and OEM services for well-known brands. These stated capabilities provide direct evidence of product customization and contract manufacturing support.
