Import Diammonium Phosphate (Dap 21-53-0) — Buy in wholesale FOB from Supplier in China

Diammonium Phosphate (DAP 21-53-0) is a granular fertilizer containing 21% nitrogen and 53% phosphorus pentoxide, derived from ammonium phosphate with the chemical formula (NH4)2HPO4. This product is offered in both tech grade and food grade forms, with a minimum P2O5 content of 53.0% and nitrogen content of at least 20.8%. The pH of a 1% aqueous solution ranges from 7.7 to 8.2, indicating moderate alkalinity suitable for most soil types. Moisture content is tightly controlled at 0.2% or less, and water-insoluble matter is limited to 0.10% or lower.

The material is produced using refined phosphoric acid and ammonia, with heavy metals capped at 0.001% as lead, arsenic at 0.0003%, and fluoride at 0.001%. These limits align with international standards for agricultural and food-grade phosphates. The product is typically crystallized and dried into free-flowing granules, with no added anti-caking agents. In industry practice, this grade is often used in compound fertilizers or as a direct application in high-value crops requiring concentrated phosphorus. The tech grade is standard for industrial blending, while the food grade meets requirements for use in animal feed additives and phosphorus fortification.

Buyers in Southeast Asia, Latin America, and Eastern Europe commonly source this grade for precision agriculture and fertigation systems. It is packed in 25kg polypropylene bags with inner polyethylene lining, or in 50kg bulk bags upon request. Standard export packaging is designed for sea freight and stackable storage. Lead times are typically 15 to 25 days after order confirmation, and terms are usually FOB Shanghai or CIF destination port. Buyers should request a certificate of analysis for each batch to verify purity and compliance with the stated limits.

Sichuan Shucan Chemical Co. Ltd. operates from Hefeng Industrial Zone in Shifang, Sichuan Province, China. The company identifies as a manufacturer and exporter focused on phosphate-based chemicals. Its listing indicates ISO 9001:2008 certification, but no verification badge or audit report is displayed on the platform. The supplier has no recorded response rate or average response time, suggesting limited buyer engagement or inactive communication channels.

The company does not claim production capacity, export volume, or client names. No factory photos, laboratory details, or workforce information are provided. The absence of response metrics and third-party verification signals means buyers must rely solely on product documentation and independent testing. The supplier's location in Sichuan places it near regional phosphate resources, but no details are given on raw material sourcing or production methods.
