Ammonium Sulphate 21-0-0-24S

21% N / 24% S | Compacted granular (SGN 200–280) & caprolactam crystal for plantations

Ammonium sulphate is the nitrogen-plus-sulphur nutrient source for plantation and Rabi programmes, and CBIL brokers it direct from the production hubs: China (Tianjin, Huanghua, Qingdao and Zhanjiang, loading for Southeast Asia and India), Northwest Europe (Belgium and the Netherlands), Japan, Taiwan, and Egypt. Cargoes move in Handysize and Supramax bulk vessels (25,000–55,000 MT), 50 kg heavy-duty woven polypropylene bags with inner polyethylene liners, and 1 MT UV-stabilised jumbo bags (FIBCs), backed by SGS or Intertek load-port certification for N, S, moisture, free acid, and mechanical granule sizing.

Our ammonium sulphate delivers 20.5–21.0% ammoniacal nitrogen (NH₄-N) and 24.0% water-soluble sulphate sulphur (SO₄-S), moisture ≤ 0.5% on crystal and ≤ 1.0% on granular, and free acid strictly capped at ≤ 0.05% H₂SO₄. Two distinct physical grades are supplied: White Caprolactam-Grade Crystalline AS (0.5–2.0 mm), highly purified with immediate aqueous solubility for compound NPK granulation plants and fertigation; and Compacted Granular AS 21-0-0-24S (2.0–4.0 mm, ≥ 90%), manufactured to a Size Guide Number (SGN) of 200–280 with crushing strength of 2.5–3.5 kgf (25–35 N) and anti-caking surface conditioning. This compacted granular grade is dimensionally matched to granular urea, DAP, and MOP, ensuring zero segregation in bulk blenders and enabling wide 24–36 m mechanical broadcast spreading. In plantation agriculture, ammonium sulphate is indispensable: Southeast Asian oil palm estates require high sulphur inputs alongside nitrogen to synthesise methionine and cysteine for maximum oil content in fresh fruit bunches (FFB) while preventing plantation chlorosis on leached tropical soils. In rubber estates, it enhances latex flow; in sugarcane, it boosts ratoon vegetative tillering; and in Indian Rabi oilseed cultivation (mustard and rapeseed), sulphate sulphur directly determines seed oil extraction percentage.
