AI-Powered supplier vetting

SummaryNINGBO YI PIAN HONG FASTENER CO., LTD. is a China-based trading company and manufacturer/factory in Ningbo, Zhejiang, established in 2001. Its stated products include fasteners, bolts, nuts, washers, thread bars, and related steel products. The supplier reports 10 production lines, 21–30 quality-control staff, over 260 production equipment units, 30 examination devices, and testing for hardness, cracks, and raw-material chemical composition. It reports multiple management-system certifications, including ISO 9001, ISO 14001, ISO/TS 16949, and BSCI. Export activity is identified from 2016, with Western Europe listed as a primary export market, while trade records also show transactions involving Brazil and Kazakhstan. Evidence is insufficient to assess after-sales service, financial credibility, customization, and customer-case quality in depth.

Supplier typeThe supplier is identified as both a trading company and manufacturer/factory, while its basic company classification also states “trade company.” Its listed business scope covers industrial equipment and components and transportation, and its product keywords focus on fasteners and related hardware.

CertificationsThe supplier lists numerous management-system certifications, including BSCI, ISO 9000, ISO/TS 16949, OHSAS/OHSMS 18001, ISO 14001, ISO 9001, ISO 14000, ISO 20000, GMP, HSE, QC 080000, and ISO 14064. The slices do not provide certificate numbers, validity dates, issuing bodies, or scope, so the assessment is based on the stated holdings only.

R&D capabilityThe supplier reports 6–10 years of R&D engineer experience and uses specialized testing equipment, including a vortex durometer, flaw detector, and direct-read spectrograph. These facts support technical and quality-engineering capability, but do not explicitly demonstrate new product development, patents, or other innovation outcomes.

Production capacityThe supplier reports 10 production lines, 21–30 quality-control staff, over 260 production equipment units, and 30 examination devices. Its stated 100% hardness testing and additional crack and chemical-composition checks provide direct evidence of organized manufacturing and inspection capability for fastener products.

Client casesTrade records associate the supplier with BOLLHOFF SERVICE CENTER LTDA in Brazil and ТОО LTNPROJECT ЛТНПРОДЖЕКТ in Kazakhstan, with recorded transactions in the supplied data. These entries demonstrate identifiable buyer-related trade activity, but the limited records do not establish customer satisfaction, project scale, repeat business, or performance outcomes.
