Ammonium Sulphate
HS3102.21.00Standard
Ammonium Sulphate (AS) provides 21% nitrogen and 24% sulphur, making it uniquely valuable in sulphur-deficient soils increasingly common across Europe, Asia, and Sub-Saharan Africa. SFERA LLC supplies crystalline and granular ammonium sulphate from Russian producers, including caprolactam co-product material and direct synthesis grades. With its acidifying effect, AS is the preferred nitrogen source for alkaline soils and chloride-sensitive crops such as tea, tobacco, and potatoes. The stable ammonium-N form reduces leaching risk compared to nitrate sources. Full laboratory analysis confirms N, S, moisture, and free acid content on every consignment.
