AI-Powered supplier vetting

SummaryShenzhen Jiuhong Century Seal Technology Co., Ltd. is identified as a Chinese manufacturer/factory and limited company based in Shenzhen, Guangdong, producing rubber seals and related products. The supplier reports ISO 9001, TS 16949 and IATF16949 certifications, approximately 150 employees, six departments, one production line, and 6–10 quality-control staff and R&D engineers. Its stated capabilities include CNC-based mold development, production of pure rubber seals, material testing, and inspection of product size, hardness and appearance. Export activity began in 2019, with exports representing 41%–50% of sales and exports conducted partly through agents. However, the provided information shows only one recorded trade transaction, does not identify customer case details, and provides no direct evidence of after-sales service processes. Financial assessment is limited because financial figures are excluded.

Supplier typeThe supplier is described as both a manufacturer/factory and a trading company, with a limited-company structure. Its stated manufacturing identity, Shenzhen location, and manufacturing-industry association indicate that it operates in a production-oriented business context, although the concurrent trading-company classification should be clarified.

CertificationsThe supplier reports TS 16949 and ISO 9001 management-system certifications, while its company description also states IATF16949 certification. These certifications provide explicit evidence of formal quality and automotive-related management systems, although certificate validity, scope and issuing bodies are not provided.

R&D capabilityThe supplier reports 6–10 R&D engineers, a technology department, and CNC-based development of new molds for rubber seal products. These details support product-development capability, but the slices do not provide evidence of patented technology, proprietary inventions or quantified innovation outcomes.

Production capacityThe supplier reports approximately 150 employees, one production line, annual output below the stated threshold, and experience producing rubber seals. It describes production monitoring, full manual and machine inspection before packing, and quality-control staffing of 6–10 people, demonstrating an established but apparently limited-scale production setup.

Customization capabilityThe product range includes rubber O-rings, gaskets, seals, oil seals, kits and OEM rubber or silicone products. The supplier states that it develops a new CNC mold for each rubber seal product and can produce essentially any pure rubber seal product, providing explicit evidence of customization support, subject to technical validation.
