AI-Powered supplier vetting

SummaryChengdu Taiyu Industrial Gases Co., Ltd. is a China-based limited trading company located in Chengdu, Sichuan, with 39 employees and operations reported in industrial, specialty, electronic, medical, rare, refrigerant, mixture, and high-purity gases. The company states that it manufactures, researches, and sells various gas products, although its registered business type is trading company and the available manufacturing-plant area is limited to 367.0 m². It reports export activity, self-operated import and export rights, and multiple payment methods. Evidence supports capabilities in gas logistics, refilling, analysis, application design, transportation, and technical consulting. However, no certification records or specific customer cases are provided. The company’s establishment date is inconsistent across the supplied information: 2012 in one record and 2002 in another.

Supplier typeThe supplier is identified as a trading company and limited company, while its company overview describes it as a manufacturer specializing in rare, industrial high-purity, specialty, electronic, and standard mixed gases. This indicates a trading-led entity that also claims manufacturing operations, but the supplied records do not fully resolve the distinction.

After-Sales capabilityThe supplier states that it provides professional logistics support, overseas local shipping-agent coordination, gas refilling, gas analysis, gas application design, gas transportation, and three months of free online technical consulting. These statements provide explicit evidence of logistics and technical support after or around purchase.

R&D capabilityThe supplier describes research activities in rare, high-purity, specialty, electronic, and standard mixed gases, and lists specialized semiconductor-related gas applications such as ion implantation, CVD, dilution, and doping. This supports product and application technical capability, although no patents, R&D investment, laboratory certifications, or new-product records are provided.

Production capacityThe supplier claims manufacturing experience and offers industrial, specialty, medical, rare, refrigerant, mixture, electronic, and high-purity gases, with services including refilling and transportation. A manufacturing plant area of 367.0 m² is reported, but no production capacity, equipment list, throughput, or factory-compliance evidence is provided.

Customization capabilityThe supplier presents one-stop gas solutions, gas application design, technical engineering consultation, standard and calibration mixtures, and a broad range of electronic and specialty gases. These details explicitly support application-oriented and potentially customized gas solutions, though specific customization examples or configurable specifications are not given.
