Minerals & Fuels
View full HS code details

Kieserite is classified under HS code 2530.20 because it is a naturally occurring mineral substance, specifically a hydrated magnesium sulfate. According to the General Rules of Interpretation (GRI) and the Chapter 25 notes, this heading covers mineral products in their natural state or those that have been washed, crushed, ground, or screened, provided they have not been chemically modified. Kieserite (magnesium sulfate monohydrate) and epsomite (natural magnesium sulfate heptahydrate) are specifically named in this subheading. The classification is determined by the mineralogical identity of the product rather than its intended use. While kieserite is frequently used as a fertilizer in the agricultural sector to provide magnesium and sulfur to crops, it remains in Chapter 25 as long as it is a natural mineral. If the product were chemically synthesized or presented in specific tablets or similar forms for retail sale as a fertilizer, the classification would shift to Chapter 31. However, bulk natural kieserite is strictly maintained under 2530.20.

Common Misclassification

Kieserite is often confused with HS code 2833.21, which covers magnesium sulfate that has been chemically synthesized or highly purified. The distinction lies in whether the product is a natural mineral (Chapter 25) or a chemical compound (Chapter 28). Additionally, it may be misclassified under 3104.20 or 3104.90 if it is perceived solely as a potassium or mineral fertilizer, but 2530.20 is the more specific code for the natural mineral form.
