AI-Powered supplier vetting

SummaryYantai Wenxu is identified as a China-based manufacturer/factory established in 2003, with chemical production, research and development, and sales integrated within the business. Its stated product portfolio includes aluminum sulfate, alum, polyaluminium chloride, calcium hydroxide, water-treatment chemicals, and related products. Evidence indicates substantial production capacity, including stated annual output of 150,000 tons overall, 30,000 tons for aluminum sulfate-series products, and 20,000 tons each for polyaluminium chloride and calcium hydroxide. The supplier reports multiple ISO-related certifications, GMP, and environmental-management credentials, as well as relevant production and hygiene-license approvals. It has exported since 2015 and reports that exports account for 51%–70% of sales. Innovation and sustainability activities are described, but evidence for after-sales service, customization, financial credibility, and specific customer cases is insufficient.

Supplier typeThe supplier is explicitly classified as a Manufacturer/Factory and is described as an integrated chemical enterprise covering production, research and development, and sales. Its stated founding year is 2003, supporting an established operating history.

CertificationsThe supplier reports ISO 9000, ISO 14001, ISO 9001, ISO 14000, GMP, and ISO 14064 certifications, plus ISO 9000:2008 quality-management certification, a national industrial product production license, and a Shandong drinking-water sanitation safety product hygiene approval. These are explicit indicators of quality, environmental, manufacturing, and product-compliance systems.

R&D capabilityThe supplier describes technology development, innovative solutions, research and development integration, green-chemistry efforts, and sustainability-oriented environmental and safety management. It also reports 11–20 years of total R&D-engineer experience, providing explicit support for innovation capability, although no quantified R&D investment or independently verified innovation results are provided.

Production capacityThe supplier offers a broad chemical product range and reports annual output of 150,000 tons overall, including 30,000 tons for aluminum sulfate-series products and 20,000 tons each for polyaluminium chloride and calcium hydroxide. It also reports 6–10 quality-control staff and factory facilities in Yantai, supporting substantial production and quality-control capacity.
