Import Diammonium Phosphate — Buy in Bulk from Supplier in China

Diammonium phosphate from Shifang Changfeng Chemical Co., Ltd is a granular fertilizer-grade compound with a minimum purity of 98% and a nutrient profile of 18% nitrogen and 46% phosphorus pentoxide (P2O5). It is produced in granular form to minimize dust and improve handling during mechanical application. The material is designed for agricultural use, with controlled solubility to ensure even nutrient release in soil.

This product is manufactured using standard wet-process phosphoric acid and ammonia reaction methods, common in Chinese fertilizer production. The granules are typically 1 to 4 mm in diameter, with low friability to reduce breakage during transport. While the listing claims industrial-grade quality, the material is not refined for food or pharmaceutical use. Typical impurities include chloride (below 0.2%) and heavy metals within Chinese agricultural standards, though exact limits are not specified.

Primary buyers include large-scale farms, cooperative fertilizer distributors, and agro-industrial processors in Asia, Africa, and Latin America. Packaging is offered in 25 kg polypropylene bags or bulk jumbo bags (1 metric ton). Trade terms are generally FOB Qingdao or Shanghai, with lead times of 15 to 25 days after deposit. MOQs start at 10 metric tons for container shipments. Buyers should request a material safety data sheet and confirm compatibility with their existing fertilizer blends.
