Product classification
HS code for Aluminum sulphate: 2833.22
Sulphates, of aluminium.
Classification of aluminum sulphate under HS 2833.22
HS code 283322 is specifically designated for sulphates of aluminium. This classification falls under Chapter 28 of the Harmonized System, which covers inorganic chemicals. Aluminium sulphate is a distinct chemical compound, typically appearing as a white crystalline solid or in solution, and is widely used in various industrial applications. The code precisely identifies this specific salt, distinguishing it from other aluminium compounds or general chemical mixtures. Its classification here reflects its identity as a pure inorganic chemical compound.

Codes often confused with 2833.22
Common mistake. Aluminum sulphate (283322) can sometimes be confused with other aluminium compounds, such as aluminium hydroxide (281800) or aluminium oxide (281800), or with general chemical preparations. The key distinction is the specific chemical composition: 283322 is exclusively for the sulphate salt of aluminium. Aluminium hydroxide and oxide are different chemical compounds, despite containing aluminium. Furthermore, 283322 is for a distinct chemical compound, not a mixture or preparation that might fall under broader residual categories like 382499 (Other chemical products and preparations of the chemical or allied industries, n.e.c.), which is reserved for products without a more specific chemical classification.
Top exporters and importers of HS 283322 (the code used for aluminum sulphate), 2025
In 2025, the largest exporter of HS 283322 (the code used for aluminum sulphate) in UN Comtrade data was Türkiye, with 20% of world exports; the largest importer in UN Comtrade data was France, with 7.3% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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).
