Import Aluminum Sulphate — Buy in Bulk from Supplier in China

Aluminum sulphate from Tianjin Ruihaiweilin Chem Co.Ltd is an inorganic compound with the formula Al₂(SO₄)₃, supplied as a coagulating agent for industrial water treatment and paper processing. The material is water soluble and functions primarily as a flocculant, binding suspended particles for removal in clarification systems. The supplier sources from Yangbei Road in Wuqing District, Tianjin, with the facility located in northern China near Beijing.

The standard form available from Chinese producers is typically the octadecahydrate, Al₂(SO₄)₃·18H₂O, though exact hydration state should be confirmed with the supplier for this listing. Industrial grades vary by iron content, with lower-iron variants preferred for paper manufacturing and higher-iron grades acceptable for municipal wastewater applications. The pH of a 1% solution typically falls between 2.5 and 4.0, reflecting the acidic hydrolysis of the aluminium cation in water. Standard packaging for bulk chemical shipment from Chinese ports includes 25 kg or 50 kg woven polypropylene bags, or 1000 kg flexible intermediate bulk containers.

Primary buyers include municipal water authorities, industrial effluent treatment plants, pulp and paper mills, and textile processors. The compound serves as a mordant in dye fixation and as a pH adjustment aid in swimming pool maintenance. Importers should confirm whether this grade meets the requirements of GB 31060-2014, the Chinese national standard for water treatment grade aluminum sulphate, or whether the supplier can provide material tested to AWWA B403-18 or EN 878 standards. Payment terms, Incoterms, and minimum order quantities must be discussed directly with Tianjin Ruihaiweilin Chem Co.Ltd, as these are not stated in the listing.
