AI-Powered supplier vetting

SummaryHualong Test Co., Ltd. is a China-based limited company in Shanghai, identified as a trading company, manufacturer/factory, and group corporation. It reports more than 10 production lines, ISO 9001 and ISO 14001 management-system certifications, 21–30 years of R&D-engineer experience, and 50 quality-control staff. Its product scope covers numerous material and mechanical testing machines and fixtures, with R&D completed for testers across more than 420 types. The supplier exports to multiple global regions and has operated export activities since 1993. It states that products follow ASTM, BS, EN, ISO, JIS, and other standards. Evidence of after-sales capability is limited to a stated after-service department, while customization is supported by broad product development evidence but not explicitly confirmed for customer-specific orders. Trade records show one transaction each for several products with a Bangladesh buyer, providing limited customer-case evidence.

Supplier typeThe supplier is explicitly identified as a trading company, manufacturer/factory, and group corporation, with a limited-company ownership structure and operations in Shanghai, China. This indicates both manufacturing and trading involvement rather than a purely intermediary profile.

CertificationsThe company states that its processes are controlled according to ISO 9001, and its management-system certifications are listed as ISO 9001 and ISO 14001. These certifications provide explicit evidence of formal quality and environmental management systems.

R&D capabilityHUALONG reports completed R&D work for testers covering more than 420 types and indicates 21–30 years of total R&D-engineer experience. This is explicit evidence of substantial product-development capability across multiple testing categories.

Production capacityThe supplier reports more than 10 production lines, manufactures a broad range of testing equipment, and maintains 50 quality-control staff. Its products cover tensile, compression, impact, fatigue, torsion, bending, and other testing applications, supporting a broad production scope.

Client casesTrade records associate HUALONG TEST CO., LTD. with CABLE INDUSTRIES OF BANGLADESH LTD. for extensometers, shear test fixtures, three-point bending fixtures, and testing grips/compression plates. Each listed product has one recorded transaction, so the evidence confirms a customer relationship but provides only a limited set of documented cases.
