AI-Powered supplier vetting

SummarySHANGHAI CHANG AI TECHNOLOGY & DEVELOPMENT CO., LTD. is identified as a China-based limited company operating as both a trading company and manufacturer/factory, although another record classifies it as a trading company. Its product scope covers oxygen, hydrogen, dew point, humidity, thermal conductivity, nitrogen and related gas analysis systems, including oxygen sensor components. The supplier reports more than 10 production lines, annual oxygen analyzer productivity of 5,000 sets, 6–10 quality-control staff and 11–20 years of R&D-engineer experience. It reports export activity since 2007, sales coverage across multiple regions, and products exported to more than 20 countries. Three Chinese marketing branches and over 30 service outlets are stated. No certification information is provided. The evidence supports production, service-network, product-development and market-experience strengths, while customization, financial credibility and certification status remain insufficiently documented.

Supplier typeThe supplier is described as a limited company based in Shanghai, China. Its business type is reported both as "Trading Company,Manufacturer/Factory" and, separately, as a "贸易公司" (trading company), indicating trading activity with a stated manufacturing role but some classification inconsistency.

After-Sales capabilityThe supplier states that it has three marketing branches and more than 30 service outlets across over 30 Chinese provinces and municipalities. It also reports technical consultation and solution provision, supporting a documented service infrastructure, although specific warranty, maintenance or response terms are not provided.

R&D capabilityThe supplier reports 11–20 years of combined R&D-engineer experience and states that it expanded from gas analyzers into gas analysis systems, technical consultations and solutions. This directly indicates product-development experience and broader technical capability.

Production capacityThe supplier reports more than 10 production lines, 6–10 quality-control staff and annual productivity of 5,000 oxygen analyzer sets. It also states order fulfillment within 15 working days in both off-peak and peak seasons, providing explicit evidence of production capacity and stated delivery performance.

Client casesThe supplier states that its products have been exported to more than 20 countries and applied in air separation, petroleum, chemical engineering, coal mining, metallurgy, electronic power, medical, food and aviation sectors. A listed oxygen sensor is intended for oxygen and hydrogen measurement in steel plants, providing application evidence, though no named customer references are supplied.
