AI-Powered supplier vetting

SummaryShanghai Jiangyi Precision Parts Co., Ltd. is a China-based limited company described as both a trading company and manufacturer/factory, offering machining parts, screws, insert nuts, hardware, shafts, standoffs, injection parts, and stamping parts. It reports broad export coverage, approximately 10 years of export experience, export sales of 41%–50%, and production information covering substantial quantities of insert nuts, machining parts, and screws. Its strengths include customization from samples, new product launches in the past year, ISO9001:2015 certification, and access to Shanghai and Ningbo ports. However, the investigation identifies important limitations: no available SDK, only one R&D engineer, no stock or overseas warehouse capability, no overseas showroom, zero reported quality-control test equipment, and procedures for complaints and corrective actions without written records. Financial information is present only as year references, so financial credibility cannot be conclusively assessed.

Supplier typeThe supplier is identified as a China-based limited company operating in Shanghai, with records describing it as both a trading company and manufacturer/factory. Its stated business and product scope covers fasteners, mechanical parts, metal and hardware products, and related industrial goods, but one record separately classifies the company as a trading company.

CertificationsThe supplier reports holding an ISO9001:2015 certificate, which is explicit evidence of a quality-management certification. No other certification is provided in the available information.

After-Sales capabilityThe supplier has procedures for customer complaints and corrective/preventive actions, but no written records are maintained. It also reports no in-stock service capability, no overseas warehouse, and no overseas showroom; these limitations indicate constrained service infrastructure despite the existence of basic procedures.

R&D capabilityThe supplier reports one R&D engineer and confirms that new products were launched during the past year, but it explicitly has no available SDK. These records show some product-development activity while also indicating limited documented R&D resources and no SDK capability.

Production capacityThe supplier reports annual outputs of 800,000,000 insert nuts, 80,000,000 machining parts, and 1,000,000,000 screws, with off-peak lead time within 15 working days and access to major logistics routes. However, it reports zero quality-control test equipment and no inventory capability, so production scale is documented but quality-control and stock-support capability are significant deficiencies.

Customization capabilityThe supplier explicitly offers customization from samples, providing direct evidence that it can support at least sample-based customized production. No broader engineering, tooling, or design-service scope is documented.
