AI-Powered supplier vetting

SummaryShandong Yankem Industry Co., Ltd is identified as a China-based manufacturer established in 2022, with operations in Shandong and a reported workforce of seven. Its stated activities cover ecological-environment materials, chemical products, technical development, and related material sales. The product scope includes water-treatment chemicals and general chemicals such as PAC, PAM, citric acid, calcium chloride, aluminum sulfate, soda ash, sodium bicarbonate, TCCA, and caustic soda. The supplier reports a 123.0 m² manufacturing plant, but the available information does not establish production scale, certifications, quality systems, customization processes, or after-sales capacity. Trade records show one transaction associated with each of two Philippine buyers for polyamine and poly aluminium chloride; these records support limited customer-case evidence but do not demonstrate broad or sustained commercial performance.

Supplier typeThe supplier is explicitly identified as a manufacturer and limited company in China, with chemicals as its commercial trade category and a product range centered on water-treatment and general chemicals. Its stated manufacturing area is 123.0 m² and its reported workforce is seven, indicating a small operating footprint.

R&D capabilityThe stated business scope includes new-material technology research and development, development, consultation, exchange, transfer, and promotion. It also references ecological-environment, bio-based, catalytic, membrane, ceramic, composite, and other advanced materials, providing explicit evidence of technology-related activities, though no proprietary technology, patents, or R&D results are documented.

Production capacityThe supplier explicitly identifies itself as a manufacturer and lists ecological-environment materials manufacturing, with a reported 123.0 m² manufacturing plant and chemical product portfolio. Nevertheless, no capacity, equipment, production volume, staffing breakdown, or manufacturing certifications are provided, so the evidence supports manufacturing status but not high-scale capability.

Client casesTwo trade records associate the supplier with Philippine buyers: one for polyamine and one for poly aluminium chloride, with one transaction recorded for each. These are concrete customer and product references, but the limited transaction count does not demonstrate a broad or sustained customer portfolio.
