Jiansu (Shanghai) Information Technology is a supply chain intermediary for China's plastics and chemical industries. Jiansu buys plastic and chemical raw materials from suppliers and resells them to customers — primarily Chinese SMEs — through an online platform accessible via website, mobile app, and WeChat Mini-Program. The platform offers a catalog of over 3,000 SKUs, including basic chemicals, plastic particles, and other materials like steel and cotton, which customers use as inputs in automotive, electronics, packaging, and construction manufacturing. Jiansu takes ownership of inventory, manages logistics, and earns the spread between procurement cost and selling price. This is a thin-margin, high-volume model — gross margins run around 0.6% — reflecting the commodity nature of the products sold and the limited pricing power available to intermediaries. Jiansu extends credit to customers on terms typically ranging from 7 to 60 days, and maintains accounts receivable insurance through PICC to manage default risk. The company serves a fragmented base of domestic Chinese SMEs, with no single customer exceeding 10% of revenue. Beyond its trading business, Jiansu is constructing a polystyrene manufacturing facility in Jiangsu Province targeting 600,000 tons of annual capacity, representing a shift from pure intermediary toward manufacturing and a significant capital commitment funded partly through IPO proceeds.
