AI-Powered supplier vetting

SummaryDemargo (Shanghai) Energy Saving Technology Co., Ltd. is a China-based limited trading company established in 2017, with 29 employees and operations in Shanghai. It offers refrigerated and desiccant compressed-air drying equipment and reports five production lines, monthly capacity of 5,000 units, and exports to multiple global regions. The supplier holds an ISO 9001:2015 management-system certificate, while a BV audit record is provided with a stated evaluation result of 0. Export activity is substantial, with 90% of sales reportedly from exports and self-operated import/export rights. Evidence supports production scale, export reach, and some customization/OEM/ODM positioning, but overseas service infrastructure, after-sales capability, customer cases, innovation details, and manufacturing-capacity controls remain insufficiently documented. Financial credibility is not assessed because financial information is excluded.

Supplier typeThe supplier is explicitly identified as a trading company and as a limited company established in Shanghai, China. Its legal/company profile is available, but the trading-company classification should be considered when evaluating manufacturing ownership and control.

CertificationsThe supplier reports an ISO 9001:2015 management-system certificate. A BV audit record is also listed with coverage from July 10, 2025 to July 9, 2026, although the stated audit evaluation result is 0 and no additional interpretation is provided.

Production capacityThe supplier reports five production lines, monthly capacity of 5,000 units, and compressed-air-dryer output of 5,000 sets, with one-month stated lead times in both seasons. However, the supplier is classified as a trading company and manufacturing-capacity reconciliation, outsourcing procedures, contracts, and inventory capability remain unknown.

Customization capabilityThe supplier explicitly states that it provides customized options with dew points from +10°C to -70°C and welcomes OEM and ODM partnerships. The broader OEM/ODM capability fields are otherwise marked unknown, so the evidence supports some customization positioning but not its full scope.
