Supplier typeThe supplier is identified as a factory and a limited company located in Kunshan, Suzhou, Jiangsu, China. It was established on March 10, 2016, and has 25 employees, indicating a relatively small manufacturing enterprise.
After-Sales capabilityThe supplier has written procedures and records for customer complaint handling, corrective and preventive actions, and service-capability assessment. However, it has no overseas warehouses, showrooms, agents or branches, has not participated in offline trade shows, and reports zero countries with overseas services.
