AI-Powered supplier vetting

SummaryThe supplier is identified as a manufacturing factory and limited company with 52 employees, valid import/export licensing, and approximately 10 years of export experience. It reports R&D activity, new products within the past year, ODM services, and broad customization options. Quality and service processes are documented, including finished-product inspection, complaint handling, and corrective/preventive actions. Production information is provided for several ceramic and thermal-analysis product categories, with 80,000 pieces stated for diesel particulate filters, but overall capacity data is incomplete. The supplier serves India and offers multiple trade and payment terms, with stated lead times within 15 working days in both peak and off-seasons. No overseas warehouse, showroom, agent/branch, or offline trade-show participation is reported. Certification holdings, customer cases, and detailed financial performance evidence are not sufficiently provided.

Supplier typeThe supplier is described as a factory, a combined company, and a limited company with 52 employees. It is not part of a larger company group and reports valid import/export licensing, indicating a directly manufacturing and exporting business structure.

After-Sales capabilityThe supplier has written procedures and records for handling customer complaints, corrective and preventive actions, and service-capability assessment. It also reports service availability in India and lead times within 15 working days in both peak and off-seasons, supporting a documented service process, although overseas service infrastructure is limited.

R&D capabilityThe supplier reports new products within the past year and provides ODM services, indicating active product-development capability. However, it reports no available SDK, which limits evidence of software or developer-interface capability but does not negate the stated product R&D capability.

Production capacityThe supplier is identified as a factory with manufacturing capacity and 52 employees, and it lists production categories including ceramic foam filters, honeycomb ceramics, thermocouples and thermal-analysis cups, riser sleeves and pouring cups, and diesel particulate filters. The stated diesel particulate filter productivity is 80,000 pieces, while capacity figures for the other categories are not supplied.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, flexible customization, and minor customization. These options are reported consistently across the R&D and design-capability information, providing direct evidence of broad customization support.
