Import Ammonium Sulfate — Buy in wholesale FOB from Supplier in China

Ammonium sulfate ((NH4)2SO4) from Shijiazhuang Kunmai Chemical Technology is a nitrogen-sulfur fertilizer produced in Shijiazhuang, Hebei Province, China. The compound provides ammoniacal nitrogen in a form less prone to volatilization than urea, coupled with sulfate sulfur readily available for crop uptake. The supplier's material is available in prilled or crystalline form, with the source indicating typical nitrogen content of 20.5 percent by weight, a standard figure for this commodity grade.

Hebei Province is a major hub for Chinese chemical and fertilizer production, with access to coking coal byproduct ammonia and sulfuric acid streams that feed ammonium sulfate synthesis. The typical manufacturing route involves neutralization of synthetic or byproduct ammonia with sulfuric acid, followed by crystallization or prilling. Product purity for standard agricultural grade typically exceeds 99 percent ammonium sulfate with moisture content below 1.0 percent, though buyers should request the specific certificate of analysis from Shijiazhuang Kunmai Chemical Technology to confirm these parameters for the offered lot.

Primary applications include direct application as a basal or top-dressing fertilizer for wheat, maize, rice, and oilseed crops, as well as blending into compound NPK formulations.
