HS Code for Epsomite

Epsomite is classified under HS code 253020 as a natural mineral. Chapter 25 of the Harmonized System covers earth, stone, plastering materials, lime, and cement. Specifically, heading 2530 includes mineral substances not elsewhere specified or included, and subheading 253020 is dedicated to kieserite and epsomite, which are natural magnesium sulphates. The classification depends on the product being in its natural state, or having been washed (even with chemical substances to remove impurities), crushed, ground, powdered, levigated, sifted, or screened. If the magnesium sulphate has been produced through a chemical process or refined to a high degree of purity beyond what is found in the natural mineral state, it would move to Chapter 28.

Products Included

• Natural epsomite mineral
• Natural kieserite
• Crude magnesium sulphate minerals
• Ground or powdered natural epsomite
• Washed natural magnesium sulphate ores

Common Misclassification

The most common misclassification for epsomite is HS code 283321. While both codes refer to magnesium sulphate, 283321 is for the chemically manufactured or highly refined version, whereas 253020 is strictly for the natural mineral. Importers often confuse the two when the natural mineral is finely ground, appearing like a chemical product. Another misclassification occurs with 251990 (magnesium oxide/magnesite), but that code is for carbonates and oxides, not sulphates. It is essential to verify the origin and processing method to distinguish between the mineral (Chapter 25) and the chemical (Chapter 28).

FAQ

What is the HS code for Epsomite?

The HS code for natural magnesium sulphate, known as epsomite, is 253020.

Can epsomite be classified in Chapter 28?

No, if the product is the natural mineral, it remains in 253020. If it is chemically synthesized or refined to a pure chemical state, it is classified under 283321.
