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

Hebei Sanyuan Jiuqi Fertilizer Co., Ltd. supplies Ammonium Sulphate in Caprolactam Grade with a nitrogen content of 21% N, based at 218 Yuxiang Street in Shijiazhuang's Equipment Manufacturing Industry Park. The material takes the form (NH4)2SO4, a standard nitrogenous fertiliser used globally to correct sulphur deficiencies and provide readily available ammoniacal nitrogen. The supplier's profile indicates availability in both granular and crystalline forms, with packaging configured for bulk shipping and containerised handling. This grade is distinguished from Steel Grade variants by its lower residual moisture and lower heavy-metal content, making it suitable for direct agricultural application and certain industrial uses.

Caprolactam Grade Ammonium Sulphate typically contains 21.0% nitrogen minimum and 24% sulphur, with moisture content kept below 0.5% to prevent caking during storage. The crystalline structure referenced in the source description appears white, though the exact crystal size distribution is not stated and should be confirmed. In industrial practice, this grade is produced as a by-product of caprolactam synthesis, yielding a purer product than coke-oven or gypsum-based routes. Typical specifications for this grade include water insolubles below 0.05% and free acidity below 0.05% as H2SO4, though buyers should verify these parameters against the supplier's certificate of analysis for each shipment.

Agricultural buyers apply this fertiliser for basal or top-dressing application in wheat, maize, rice, and oilseed crops where both nitrogen and sulphur are required. It is also used in blended fertiliser formulations and as a raw material in flame retardant and food additive manufacturing. The supplier holds a harbor trust tier, with a response rate of 0.00% and zero average response hours recorded on the profile, so buyers should establish direct communication channels before finalising orders. Packaging options referenced include bulk and bagged formats, with FOB terms mentioned as available.
