Agricultural & Industrial Grade Diammonium Phosphate DAP CAS 7783-28-0 NPK Fertilizer & Industrial Material

Diammonium Phosphate (DAP, Ammonium Phosphate Dibasic, CAS:7783-28-0,EINECS:231-987-8, HS Code:3105300000, molecular formula (NH₄)₂HPO₄, MW:132.06) is a white granular or crystalline powder produced via neutralization reaction of phosphoric acid with ammonia. Our product is available in two mainstream specifications: agricultural grade (18-46-0 NPK) and industrial grade (21-53-0 NPK). It exhibits excellent water solubility, high nutrient availability and stable chemical properties, providing both essential nitrogen and phosphorus nutrients for plants and serving as a versatile raw material for various industrial sectors. As the most widely used high-concentration nitrogen-phosphorus compound fertilizer globally, it is suitable for all soil types and crops. Our product strictly complies with GB 10205-2009 and HG/T 4132-2021 standards, ensuring consistent quality for agricultural and industrial applications.
