HS Code 2530.20 – Kieserite, epsomite (natural magnesium sulphates)
HS code 2530.20 is the 6-digit subheading for kieserite, epsomite (natural magnesium sulphates). It is used for kieserite fertilizer, epsomite (natural), magnesium sulphate monohydrate (natural), animal feed grade kieserite and industrial magnesium sulphate.
What HS 2530.20 covers
This HS code covers natural magnesium sulphates, specifically kieserite and epsomite. These minerals are primarily traded for their high magnesium and sulfur content, making them invaluable in agriculture as fertilizers and soil conditioners. Kieserite (magnesium sulphate monohydrate) is widely used to correct magnesium deficiencies in crops, while epsomite (magnesium sulphate heptahydrate), commonly known as Epsom salts, has applications in agriculture, animal feed, and even some industrial processes. Exporters are typically countries with significant natural deposits, such as Germany and China, which have established mining and processing operations. Importers are predominantly agricultural nations worldwide, seeking to enhance crop yields and animal health. The trade in these natural sulphates is driven by global food production demands and the need for efficient nutrient management in farming.

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).
