AI-Powered supplier vetting
SummaryTaizhou Jiaxin Metals Co., Ltd. is identified as a China-based limited company described as both a manufacturer/factory and a group corporation, although another record classifies it as a trading company and reports only three employees. It offers brass plumbing products and states substantial output across drains, pipe fittings, valves, and related items. The supplier supports multiple customization methods, exports to broad international markets, and holds BSCI and ISO 9001 certifications. Its descriptions mention CAD/3D design, production equipment, quality-control personnel, and R&D engineers. However, it explicitly lacks OEM service for popular brands and has no available SDK. Financial records are represented only by years rather than performance values, while after-sales service, customer-specific cases, and several sustainability controls are not sufficiently documented.
CertificationsThe supplier reports holding BSCI and ISO 9001 management-system certifications. These are explicit certifications relevant to social compliance and quality management, supporting a positive assessment for this field.
R&D capabilityThe supplier explicitly reports no available SDK and no OEM service for popular brands. It does report CAD and 3D design use, design and development competence, and 6–10 years of total R&D-engineer experience, but the explicit lack of SDK and popular-brand OEM capability prevents a clear positive assessment of innovation capability.
Production capacityThe supplier is described as a manufacturer/factory producing brass plumbing products, with stated output of 1,000,000 sets of brass drains, 2,000,000 pieces of brass pipe fittings, and 1,000,000 pieces each across several other product categories. Its facilities include melting furnaces, a coated-sand production line, molding machines, multi-station machines, and leak-testing equipment, supporting a positive production-capability assessment.
Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. Its stated CAD and 3D design capability further supports the ability to handle customized product development.
