AI-Powered supplier vetting
SummaryZhejiang Zhenhang Industrial Group Co., Ltd 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 applications. Evidence indicates IATF16949 and TS16949 system implementation, dedicated R&D personnel, quality-control staff, multiple production lines, and broad filter-product coverage. The supplier has exported since 2015, with exports representing 71%–90% of total sales and markets including Europe and other regions. It states that it provides after-sales responses within 24 hours for relevant issues. Production information is inconsistent across slices: one record lists five lines and specified product volumes, while company descriptions claim eight lines and output exceeding 3 million pieces or sets. Customization capability and specific customer cases are not sufficiently documented.
Supplier typeThe supplier is explicitly classified as a trade company and limited company, while its business information and product descriptions show manufacturing and processing activities focused on filters. It therefore appears to combine trading and manufacturing-related operations, but the exact legal operating model is not fully clarified.
CertificationsThe supplier explicitly reports IATF16949 certification and states that it follows or has implemented the TS16949 system. These automotive-quality-system references support a positive assessment of its formal quality-management capability.
After-Sales capabilityThe supplier states that it will complete regular product-related after-sales service within the specified time and resolve problems within 24 hours. This is explicit evidence of a defined response commitment, although actual service performance is not independently documented.
R&D capabilityThe supplier reports 17 years of total R&D engineer experience, independent research and development, technological innovation as a strategic policy, and experience taking projects from concept definition through industrialization. These statements provide direct support for R&D and innovation capability.
Production capacityThe supplier reports 142 employees, five production lines in one operational record, a 15,353 m² manufacturing plant, and stated output for oil filters, fuel filters, fuel-water separators, and hydraulic filters. Its descriptions separately claim eight modern lines and output exceeding 3 million pieces or sets, creating an unresolved data inconsistency, but the combined evidence still confirms substantial production activity and broad product coverage.
