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.

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.
