Products classified under HTS 2530.20.20.00
Kieserite-Epsom Salt Mineral Blend
A natural mixture of kieserite (monohydrate) and epsom salts (heptahydrate) from evaporite deposits. Falls under HTS 2530.20.2000 as natural magnesium sulfates including epsom salts per statistical notes. Primarily used in soil amendment for magnesium-deficient crops.
Evaporite Epsom Salt Coarse Grade
Coarse crystalline epsom salt extracted from ancient evaporite basins like the Permian deposits. HTS 2530.20.2000 covers this natural magnesium sulfate before grinding or refining. Ideal for bulk agricultural spreading.
Agricultural Epsom Salt Nuggets
Large nugget-form natural epsom salts for slow-release soil application. Specifically under HTS 2530.20.2000 as unprocessed natural epsom salts per chapter exclusions. Excludes synthetic forms explicitly noted in chapter notes.
Bulk Natural Magnesium Sulfate Heptahydrate
Unrefined bulk epsom salt (MgSO4·7H2O) from natural deposits for industrial magnesium extraction. HTS 2530.20.2000 per hierarchy for epsom salts specifically. Excludes dolomite mixes or processed forms noted in chapter exclusions.
Natural Epsom Salt Crystals
Naturally occurring epsom salts (magnesium sulfate heptahydrate) mined from mineral deposits, appearing as transparent to white crystals. Classified under HTS 2530.20.2000 as natural epsom salts, distinct from synthetic or precipitated magnesium sulfate in heading 2833. Used primarily in agriculture as a magnesium fertilizer source.
Pharmaceutical-Grade Natural Epsom Crystals
High-purity natural epsom salt crystals selected for minimal impurities, suitable for pharma laxative production. Remains HTS 2530.20.2000 as the natural mineral form before chemical processing. Distinguished by mining source certification.
