HS Code 2833.22 – Sulphates; of aluminium
HS code 2833.22 is the 6-digit subheading for sulphates, of aluminium. It is used for aluminium sulphate (solid), liquid aluminium sulphate, papermaker's alum, water treatment alum and ferric aluminium sulphate.
What HS 2833.22 covers
Aluminium sulphate, often referred to as alum, is a widely traded inorganic compound crucial for several industrial applications. Its primary uses are in water purification as a coagulant, in the paper industry as a sizing agent, and in the textile industry as a mordant. It also finds application in gardening to lower soil pH and in some food additives. The international trade involves chemical manufacturers, water treatment facilities, and pulp and paper mills as key importers and exporters. The global market for aluminium sulphate is driven by the continuous need for clean water and paper products, making it a high-volume commodity. Trade often involves various grades, including liquid and solid forms, with specifications tailored to the specific industrial process. Its role in municipal water treatment ensures a stable and essential demand worldwide.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
