AI-Powered supplier vetting

SummaryChengdu Taiyu Industrial Gases Co., Ltd. is a China-based limited trading company established in 2012, offering specialty, industrial, electronic, and mixture gases. It reports ISO9001:2015 and ISO14001:2015 certification and has documented supplier-service procedures with 30 qualified service suppliers. Its service coverage is primarily export-oriented through port-based delivery, with no overseas warehouses, showrooms, agents, or branches, although it has participated in an offline trade show. R&D is limited: the company identifies as a professional technical supplier and supports sample-based customization, but reports no new products in the past year, no 3D software design, no ODM, no SDK, and no popular-brand OEM capability. The available information does not establish in-house production capability, financial strength, after-sales performance, or customer case history.

Supplier typeThe supplier is identified as a trading company and limited company based in Chengdu, Sichuan, China, rather than a stated manufacturer. Its offered products are specialty, industrial, electronic, and mixture gases, and it is not part of a larger company group.

CertificationsThe supplier reports holding ISO9001:2015 and ISO14001:2015 certificates, along with other unspecified certifications. These explicitly support quality-management and environmental-management certification coverage.

After-Sales capabilityThe supplier has written procedures and records for assessing service capability, 30 qualified service suppliers, and stated quotation and payment options. However, it has no overseas warehouse, showroom, agent, or branch, and reports zero countries with overseas services, indicating limited local after-sales infrastructure outside China.

R&D capabilityThe supplier identifies as a professional technical supplier and has one year of total R&D-engineer experience, but reports no new products in the past year, no 3D software design, no ODM, and no SDK. These stated limitations indicate weak demonstrated innovation capability.

Customization capabilityThe supplier reports customization from samples as an R&D-related design service. However, it does not provide 3D software design, ODM, or SDK services, so customization is evidenced only in a limited sample-based form.
