AI-Powered supplier vetting

SummaryCommander Group Ltd. is a China-based trading company established in 2014, headquartered in Jiangyin, Jiangsu. It supplies surveying instruments and accessories, offers OEM/ODM services, and reports ISO 9001:2015 quality-system certification. The supplier states that it operates two production lines, has 21–30 quality-control staff, and can fulfill orders within 15 working days in both peak and off-peak seasons. However, the records also describe only five total employees, one year of R&D-engineer experience, and a 100.0 m² manufacturing plant, creating uncertainty about the scale and structure of its production and technical capabilities. Export activity is substantial, with 71%–90% of sales reported as exports and markets across Asia, Europe, Australia, and North America. The provided information does not establish after-sales service performance, financial credibility, or specific customer cases.

Supplier typeThe supplier is explicitly identified as a trading company, legally organized as Commander Group Ltd., headquartered in Jiangyin, Jiangsu, China. Its stated business focuses on marketing surveying equipment and accessories, although other records also report production lines and a manufacturing location.

CertificationsThe supplier states that it conducts quality control according to the ISO 9001 quality-management system, and specifically lists an ISO 9001:2015 certificate. This provides explicit evidence of certification-related quality-system compliance.

Production capacityThe supplier reports two production lines, 21–30 quality-control staff, order fulfillment within 15 working days in both peak and off-peak seasons, and a 100.0 m² manufacturing plant. These are explicit operational indicators, but the small stated plant area and limited supporting production detail prevent a strong assessment of manufacturing scale.

Customization capabilityThe supplier explicitly offers OEM and ODM services and has its own import-export rights, indicating that it supports customized sourcing or product arrangements. The records do not define customization scope, tooling resources, minimum order requirements, or examples of completed customized products.
