AI-Powered supplier vetting

SummaryShanghai Guanru Chemical Co., Ltd. is identified as a China-based limited company engaged in chemical trade and manufacturing. The available information indicates experience in defoamers, water-treatment agents, papermaking additives, and related chemicals, with stated production bases and historical sales or capacity figures. It reports ISO 9001 and environmental-management certifications, as well as a broader list of management-system certifications. The supplier describes R&D, technical support, and product solutions for multiple industries, with 21–30 years of total R&D-engineer experience and a 2017 product-performance achievement. Evidence of customer activity includes one named buyer and one product shipment description. However, the slices do not sufficiently establish after-sales performance, customization execution, or overall financial credibility.

Supplier typeThe supplier is described as a trade company and also as a manufacturer/factory, with a limited-company structure. Its stated business covers chemicals and related industrial products, including defoamers, water-treatment products, and papermaking additives, indicating a combined manufacturing and trading profile.

It also lists BSCI, ISO 9000, TS 16949, ISO 14001, ISO 9001, ISO 14000, and ISO 20000; however, the slices do not provide certificate numbers, validity dates, or scope details.

R&D capabilityThe supplier states that it integrates chemical R&D, production, sales, and technical service, was founded by experienced defoamer R&D professionals, has 21–30 years of total R&D-engineer experience, and completed emulsion-polymerization chemicals for high-viscosity systems in 2017. It further claims that the product performance reached the level of similar foreign products, supporting a positive innovation assessment.

Production capacityThe supplier reports multiple production bases and stated defoamer capacities, including 6,000 tons annually in 2007 and 30,000 tons annually in 2011, along with historical defoamer sales exceeding 30,000 tons in 2014 and 40,000 tons in 2016. It also describes a large-scale Anhui base planned with phased capacity, but the slices do not confirm the later project’s completion or current operating capacity.

Client casesThe records include one named associated buyer, CÔNG TY TNHH SẢN XUẤT THƯƠNG MẠI GIẤY LÂM MINH PHÁT, and a product description for a paper-industry TPC Acrylate copolymer shipment. This provides a concrete customer and application reference, but the slices do not establish the relationship’s duration, order volume, performance results, or broader customer portfolio.
