AI-Powered supplier vetting

SummaryShaanxi SGJ International Co., Ltd. is a China-based limited company in Xi’an, identified as both a trading company and manufacturer/factory. Its stated focus is ceramic-metal seal assemblies, alumina and zirconia ceramics, feedthrough electrodes, Kovar parts, isolators, vacuum brazing, and related products. The supplier reports three production lines, annual output of 1,000,000 ceramic-metal seal assemblies, 6–10 quality-control staff, and 6–10 R&D engineers. It states a lead time of within 15 working days during off-peak periods and exports to multiple global regions. Listed management certifications include ISO 9001, ISO 14001, ISO 14000, TS 16949, BSCI, and others, although the slices do not specify certificate scope or validity. The supplier claims after-sales support and a 70-year history, but these claims are not independently substantiated in the provided data. Trade records show one transaction associated with a Vietnamese buyer, providing limited customer evidence.

Supplier typeThe supplier is classified as a trading company in its company nature, while its business-entity profile also identifies it as a trading company, manufacturer/factory, and group corporation. This indicates combined trading and manufacturing positioning, although the slices do not clarify which products are internally manufactured.

CertificationsThe supplier lists BSCI, ISO 9000, OHSAS/OHSMS 18001, TS 16949, ISO 9001, ISO 14001, ISO 14000, ISO 20000, GMP, HSE, ISO 14064, and QC 080000, and states support for hazardous-substance restrictions in electrical and electronic equipment. The data does not provide certificate numbers, issuing bodies, validity periods, or applicable sites, so the certification claims cannot be fully verified.

After-Sales capabilityThe supplier explicitly states that customer satisfaction, after-service, and related competence are supported, and says customers can continue addressing the company with questions. These are direct company claims, but no service process, response-time commitment, warranty policy, or service staffing evidence is provided.

R&D capabilityThe supplier reports 6–10 years of total R&D engineer experience and describes technical work involving ceramics, metals, vacuum brazing, and ceramic-metal seal assemblies for material, energy, and information applications. This supports some technical development capability, but there is no evidence of patents, proprietary designs, new-product launches, or documented R&D results.

Production capacityThe supplier reports three production lines, annual output of 1,000,000 ceramic-metal seal assemblies, 6–10 quality-control staff, and off-peak lead time within 15 working days. It also identifies broad export coverage and Xi’an as the nearest port location, indicating an operating production and logistics setup; however, capacity data is supplied for ceramic-metal seal assemblies only.

Client casesThe provided trade records associate the supplier with CÔNG TY TNHH TRACE - TEC VIỆT NAM and Vietnam, with one transaction reported in each record. This is evidence of at least one named buyer relationship, but the records are limited and do not provide product performance, repeat-order history, customer references, or broader verified case studies.
