Magnesium Sulfate

Magnesium sulfate — commercially familiar as Epsom salt in its heptahydrate form — serves industrial roles in agriculture (as a soil amendment and fertilizer additive), chemical manufacturing, and food processing, as well as consumer health applications. The entire heading resolves to a single tariff line (2833210000), so classification is straightforward, though purity and hydration state (anhydrous, monohydrate, heptahydrate) affect pricing and end-use suitability. China dominates US supply by a wide margin, with Japan, Germany, Mexico, and India also among the top sources.
