AI-Powered supplier vetting

SummaryShandong Boyu Chemical Co., Ltd. is identified as a Chinese manufacturer/factory engaged in chemical trade, with production and supply activities covering organic intermediates, inorganic chemicals, food additives, dyes, pigments, and related products. The supplier reports ISO 9001 certification, a citric acid annual productivity figure of 150,000 tons, self-operated import and export rights, and exports representing 90% of total sales. It claims exports to more than 100 countries and stable cooperation with more than 200 countries, although these statements are not independently verified in the provided information. After-sales service and product quality are emphasized in company descriptions. Audit information identifies TÜV Rheinland, but the audit result and several operational capability fields are not sufficiently interpretable or remain unknown. Evidence is insufficient to assess financial credibility, innovation, customization, or specific customer cases.

Supplier typeThe supplier is explicitly classified as a manufacturer/factory and limited company in China, with operations described as integrating chemical R&D, production, and supply. Its stated product scope includes organic intermediates, inorganic chemicals, food additives, daily chemicals, dyes, pigments, and related chemical materials.

CertificationsThe supplier reports ISO 9001 certification. TÜV Rheinland is identified as the audit organization, with an audit period from 2023-10-31 to 2024-10-30, but the stated audit evaluation result is “0” and its meaning is not explained; therefore, the clearly supported certification evidence is limited to ISO 9001.

After-Sales capabilityThe supplier explicitly states that it provides good after-sales service and attributes its domestic and international reputation to product quality and after-sales service. These are supplier claims, with no detailed service process, response-time data, or independent verification provided.

Production capacityThe supplier is identified as a manufacturer/factory and reports annual productivity of 150,000 tons for citric acid, alongside a broad chemical product portfolio. However, no capacity details are provided for most other products, and manufacturing-capacity contract status is unknown.
