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

SHANDONG GUANSHENG NEW MATERIAL TECHNOLOGY CO., LTD. supplies ammonium sulphate fertilizer from its base in Zichuan District, Zibo City, Shandong Province. The product is specified at minimum 21.0% total nitrogen and minimum 24% sulphur, with maximum 1.0% moisture, and is described as white crystalline or granular in appearance. The supplier operates from Shuangyang Industrial Park and holds organic supplier tier and harbor trust tier classifications. No response rate data is available on the listing, and the company does not state production capacity or export volume figures.

The 24% sulphur content distinguishes this as a dual-nutrient fertilizer, with sulphur in plant-available sulphate form supporting protein synthesis and enzyme function in crops. The crystalline structure indicates a specific manufacturing route, typically reaction of ammonia with sulphuric acid followed by controlled crystallization, while granular material suggests drum or pan granulation for improved handling. Maximum 1.0% moisture is standard for storage stability and minimises caking during transport. The white colour indicates low iron and organic impurity levels, a typical quality marker for technical or fertilizer-grade material rather than by-product ammonium sulphate from caprolactam or steel production.

Application sectors include agriculture for cereals, fruits, and vegetables, horticulture, and landscaping, with particular value on alkaline soils where the mild acidifying effect of ammonium sulphate improves micronutrient availability. The supplier mentions ISO and SGS certifications though buyers should verify current validity and scope. Packaging flexibility and trade terms including FOB and CIF are referenced but require direct confirmation. Letter of credit and telegraphic transfer payment options are noted. MOQ, exact lead time, and price are not stated and must be negotiated with the supplier.
