AI-Powered supplier vetting

SummarySUPERGREEN TECH CO., LTD. is identified as both a trading company and manufacturer/factory based in Chongqing, China. The supplier reports ISO 9001 and ISO 14000 certification, robust R&D resources, 50 years of total R&D engineer experience, and six to ten quality-control staff. Its stated production portfolio includes solar air conditioners, refrigerators/freezers, street lights, and pest-control lamps, with two production lines and stated annual product quantities. The company offers technical training, before- and after-sales service, and 24-hour customer feedback and support. It also states that it provides OEM solutions and special designs. Evidence of customer activity is limited to a small number of recorded transactions involving buyers in Bangladesh and India, including a sample solar air-conditioner shipment for R&D purposes. Financial credibility cannot be determined because the available information does not provide sufficient non-financial evidence for that assessment.

Supplier typeThe supplier is explicitly classified as both a Trading Company and Manufacturer/Factory. Its description also presents it as a manufacturer offering its own Solargreen brand and OEM solutions, supporting a combined manufacturing and trading profile.

CertificationsThe supplier reports holding ISO 9001 and ISO 14000 certification for its management systems. These certifications are explicit evidence of formal quality and environmental management systems, although no certificate numbers, issuing bodies, or validity dates are provided.

After-Sales capabilityThe supplier states that it provides technical training, before- and after-sales technical services, and fast 24-hour feedback and customer support. This is direct evidence of an after-sales service commitment and defined response capability.

R&D capabilityThe supplier reports robust R&D capabilities, a strong R&D team, 50 years of total R&D engineer experience, and the ability to develop a full range of solar appliances. A sample solar air-conditioner shipment for R&D purposes also appears in the trade records, supporting active product-development activity.

Production capacityThe supplier reports two production lines and stated annual capacities of 50,000 solar air conditioners, 20,000 solar refrigerators/freezers, 50,000 solar street lights, and 80,000 solar pest-control lamps. It also states that a 2019 facility move doubled production capacity, providing explicit evidence of established production operations.

Customization capabilityThe supplier explicitly states that it provides flexible solutions for special customer requirements, special designs, and customized OEM solutions in addition to standard products. These statements directly support customization capability.

Client casesTrade records associate the supplier with IMPRESS MOTOR & FAN INDUSTRIES in Bangladesh for fan components and with GIGGLE AND BYTES in India for a sample solar air-conditioner shipment for R&D purposes. These records provide identifiable customer and shipment examples, but the evidence is limited to three recorded transactions and does not establish broad or long-term customer performance.
