AI-Powered supplier vetting

SummaryJiaxing Yheng Group Limit is a China-based limited company in Zhejiang, with a stated establishment date of November 17, 2021 and three employees in the supplied company profile. It offers a broad fastener range, including nuts, bolts, washers, screws, anchors, threaded rods, rivets, CNC parts, and solar accessories. The supplier states that it holds ISO 9001 certification, operates four production lines, and applies quality checks from raw materials through packaging. It reports export activity beginning in 2012 and exports to multiple regions, although another record identifies domestic markets as primary and shows only one recorded transaction. The supplier claims drawing-based non-standard-part production, technical personnel, one year of R&D experience, and customer responsiveness within one hour. Several operational claims are inconsistent or insufficiently corroborated, particularly company history, employee count versus production scale, output data, and customer-track-record depth.

Supplier typeThe supplier is identified as a combined business entity and a limited company based in Jiaxing, Zhejiang, China. The profile states an establishment date of November 17, 2021 and three employees, providing a clear legal and organizational classification.

CertificationsThe supplier explicitly states that it has obtained ISO 9001 quality management system certification and that third-party inspection is accepted. The slices do not provide a certificate number, issuing body, validity period, or verification record, but they do contain a direct certification claim.

After-Sales capabilityThe supplier states that questions will receive a reply within one hour and emphasizes considerate service, customer satisfaction, and peace of mind in product use. These statements support communication responsiveness, but no evidence is provided regarding warranty terms, complaint handling, returns, replacement procedures, or technical after-sales support.

Production capacityThe supplier describes production and inspection stages covering raw materials, cold heading, threading, cleaning, inspection, and packaging; it also reports four production lines, over 9,000 square meters of production area, and stated output for wedge anchors, DIN 934, and DIN 975. However, the stated three employees and conflicting company-history information create verification concerns, so the scale claims should be validated before reliance.

Customization capabilityThe supplier explicitly states that it produces stamping and non-standard parts according to customer drawings and aims to create tailored products for each customer. This is direct evidence of drawing-based and customized production capability, although the slices do not specify tolerances, tooling resources, or sample-development procedures.
