AI-Powered supplier vetting

SummaryShandong Bluesun Chemicals Co., Ltd. is identified as a China-based manufacturer/factory specializing in paper-making and water-treatment chemicals. The supplier reports ISO 9001 and ISO 14001 certifications, R&D and quality-control personnel, six production lines in one data slice and twelve advanced production lines in another, and product coverage including paper sizing, strength, coating, functional and coloring agents. It states export activity across multiple regions and reported lead times within 15 workdays in both peak and off-peak seasons. Evidence is insufficient to confirm after-sales service processes, customization capability, or verifiable customer cases. The records also contain inconsistencies, including different company names and company classifications, which should be clarified during due diligence.

Supplier typeThe primary supplier records identify Shandong Bluesun Chemicals Co., Ltd. as a Manufacturer/Factory in Weifang, Shandong, China, producing paper-making and water-treatment chemicals. However, another slice lists Shandong Kairui Chemical Co., Ltd. as a trade company, creating a company-identity and entity-classification inconsistency that requires verification.

CertificationsThe supplier explicitly reports ISO 9001 and ISO 14001 certification holdings. These certifications support stated quality-management and environmental-management capabilities, although certificate numbers, validity dates, and issuing bodies are not provided.

R&D capabilityThe supplier states that it focuses on advanced technology research, uses refined raw materials and DCS-controlled production lines, and has 18 R&D personnel among 120 employees. Its stated green-chemicals approach and turnkey paper-chemical solutions further support an innovation orientation.

Production capacityThe supplier reports six production lines in one record and twelve advanced production lines in another, along with paper and water-treatment chemical product ranges. It also states lead times within 15 workdays during both peak and off-peak periods, indicating claimed production responsiveness, although the production-line discrepancy should be clarified.
