AI-Powered supplier vetting

SummaryZhejiang Zhenhang Industrial Group Co., Ltd is a China-based limited company focused on filters for agricultural machinery, construction machinery, heavy-duty vehicles, and related applications. Evidence indicates established manufacturing and export activity, with 5 reported production lines, a 15,353 m² manufacturing plant, 142 employees, and product output across oil, fuel, fuel-water separator, and hydraulic filters. The supplier reports IATF16949 and TS16949-related quality-system implementation, 17 years of R&D engineer experience, and 6–10 quality-control staff. It exports 71%–90% of sales, began exporting in 2015, and serves Europe and other international markets. Its after-sales statement commits to resolving regular product-related issues within 24 hours, although customization capability and specific customer cases are not sufficiently documented. Company financial information is excluded.

Supplier typeThe supplier is identified as a Chinese limited company and trade company associated with manufacturing, specializing in filters for agricultural machinery, construction machinery, heavy-duty vehicles, and related industrial applications. Its reported activities integrate development, production, sales, and service, although the company is also classified as a trade company.

CertificationsThe supplier explicitly reports IATF16949 certification and describes implementation of the TS16949 system, together with strict production-system practices. This provides direct evidence of automotive-oriented quality-system capability, although no certificate scope or validity details are provided.

After-Sales capabilityThe supplier states that it completes regular product-related after-sales matters within the specified time and aims to solve problems within 24 hours. Its integrated development, production, sales, and service model further supports service coverage, though independently verified service performance is not provided.

R&D capabilityThe supplier reports independent research and development, technological innovation as a strategic policy, advanced production equipment, and 17 years of total R&D engineer experience. Its stated product-development focus and technical support activities indicate innovation capability, although no specific patents, new-product records, or quantified R&D investment are provided.

Production capacityProduction capability is supported by 142 employees, 5 reported production lines, a 15,353 m² manufacturing plant, stated output for multiple filter categories, and more than 500 filter types. However, the slices contain inconsistent facility descriptions, including one statement of 8 production lines and a factory area exceeding 60,000 m², so the exact current scale is not fully consistent.
