Pharmaceutical-Grade Natural Epsom Crystals
Pharmaceutical-grade natural epsom crystals are high-purity natural epsom salt selected for minimal impurities, intended for pharma laxative production. As the natural mineral form before chemical processing, they remain classifiable under tariff item 2530.20.00, provided they are not formulated into medicaments, which are excluded by chapter note 2(c).

Agricultural Epsom Salt Nuggets
Agricultural epsom salt nuggets are large natural epsom salt forms intended for slow-release soil application. As unprocessed natural magnesium sulphate heptahydrate, they fall under tariff item 2530.20.00, which covers epsomite and natural magnesium sulphates, provided no chemical processing has occurred.
Bulk Natural Magnesium Sulfate Heptahydrate
Bulk natural magnesium sulfate heptahydrate is unrefined epsom salt from natural deposits, used for industrial magnesium extraction. As a natural mineral in crude form, it is classifiable under tariff item 2530.20.00, which includes epsomite and natural magnesium sulphates, and is not excluded by chapter notes.
Crude Kieserite Crystals
Crude kieserite crystals are naturally occurring magnesium sulfate monohydrate minerals extracted from evaporite deposits. They are minimally processed by washing to remove surface impurities, which does not alter their crystalline structure, and are therefore classified under tariff item 2530.20.00 as natural magnesium sulphates.
Evaporite Epsom Salt Coarse Grade
Evaporite epsom salt coarse grade consists of coarse crystalline epsom salt extracted from ancient evaporite basins. Before grinding or refining, it is a natural magnesium sulphate heptahydrate, classifiable under tariff item 2530.20.00, as the extraction and sizing are mechanical processes permitted by chapter note 1.
Kieserite-Epsom Salt Mineral Blend
Kieserite-epsom salt mineral blend is a natural mixture of kieserite monohydrate and epsom salt heptahydrate from evaporite deposits. As a natural combination of magnesium sulphates, it falls under tariff item 2530.20.00, which covers both kieserite and epsomite, provided no mixing with other substances has occurred.
Kieserite Evaporite Rock
Kieserite evaporite rock consists of kieserite-bearing material from ancient salt deposits, crushed to fist-sized pieces for transport. The crushing is a mechanical process permitted by chapter note 1, and the rock remains a natural magnesium sulphate, classifiable under tariff item 2530.20.00.
