Alum, a chemical compound commonly known as potassium aluminum sulfate, is widely used in water treatment, paper manufacturing, and as a coagulant due to its ability to precipitate impurities—key attributes include solubility, purity, and particle size. Conceptually, alum is structured into subtypes like potash alum and ammonium alum, each differing in chemical composition and application suitability, with purity and moisture content being critical attributes that influence performance. To source it effectively on a B2B platform, first filter by application (e.g., water treatment), then verify product specifications such as chemical formula, minimum purity (e.g., ≥98%), and packaging size; for example, select a 50kg bag of potash alum with 98% purity for water purification or a 25kg container of ammonium alum for paper production. Before finalizing, verify with suppliers that they provide a certificate of analysis (CoA), confirm the manufacturing location, and ask for test results to ensure consistency and compliance with industry standards.

Alum is primarily imported in Asia, Europe, and North America, with China, India, and Germany being key destination markets. Commonly traded variants include potassium alum (also known as potassium aluminum sulfate), ammonium alum, and sodium alum, with potassium alum being the most widely exported. Supplier listings typically specify material composition (e.g., potassium aluminum sulfate), chemical grade (e.g., 99.5% purity), and packaging (e.g., 25kg bags). Potassium alum is especially preferred in Europe and North America for use in water treatment and food processing, while ammonium alum is more commonly used in Asia for industrial applications. A key differentiator is the chemical purity, with 99.5% and above being standard in high-demand markets, and packaging sizes of 25kg or 50kg being the most common in B2B trade. This data is verified through verified supplier listings on Freshdi, ensuring accuracy and reliability in trade specifications.

Alum, a versatile chemical compound used in water treatment, paper manufacturing, and textile processing, is categorized under industrial chemicals on Freshdi, with common applications in water purification, dyeing, and coagulation. It is widely adopted by industries such as wastewater management, paper mills, and textile producers to improve efficiency and product quality. A plant manager at a wastewater treatment facility in India may search for alum suppliers to enhance sedimentation processes, while a textile engineer in Bangladesh might look for alum to improve fabric dyeing consistency—both scenarios are common triggers for buyers seeking reliable B2B sourcing on Freshdi.

Freshdi lists alum suppliers with verified credentials such as ISO 9001, ISO 14001, and CE certification, which are commonly expected to establish reliability in B2B deals. Buyers typically look for suppliers with at least 5 years of operation and proven exporting experience to key regions like China and India. Common trade terms include FOB Shanghai and FOB Mumbai, with payment terms often set at 30% advance payment and 70% against bill of lading, reflecting standard practices in international alum procurement.
