Dipotassium phosphate (DKP), with the chemical formula K2HPO4·3H2O and a molecular weight of 228.23, is supplied as white or colorless crystals or powder that readily absorbs moisture. It dissolves easily in water, forming a slightly alkaline solution with a pH range of 8.8 to 9.2, and only partially dissolves in alcohol. The anhydrous form has a relative density of 2.338, and dehydration occurs at 204°C. This product meets the industrial standard Q/70894764 03-1998, with both industrial and superior grades maintaining a minimum of 98.0% main content and 30.50% P2O5.
The superior grade includes controlled limits for heavy metals, with lead capped at 0.001%, arsenic at 0.0003%, and fluoride at 0.003%, while water-insoluble content remains below 0.10%. Moisture content is held at 3.0% for both grades. These specifications align with typical food-grade and agricultural-grade DKP benchmarks, where purity and contaminant control are critical for use in fermentation and hydroponic systems. The material is hygroscopic and requires dry storage to prevent caking and degradation.
DKP is primarily used as a high-efficiency potassium-phosphorus fertilizer in controlled-release agriculture and as a buffer in microbial culture media for fermentation processes. Buyers include agrochemical distributors, biotech labs, and specialty fertilizer manufacturers sourcing for precision nutrient formulations. Packaging is in plastic-woven sacks with polythene liners, available in 25kg, 50kg, or 1000kg net weights. Storage must be in ventilated, dry conditions to preserve integrity. Trade terms are typically FOB China port, with bulk shipments preferred.

Before ordering, verify the batch-specific Certificate of Analysis for P2O5, K2O, moisture, and heavy metals against the supplier’s stated limits. Request test reports from an ISO 17025 accredited lab, not internal data. Confirm the product matches the Q/70894764 03-1998 standard by reviewing the full document, as some suppliers use outdated versions. Do not accept samples without sealed, labeled containers and batch codes matching the COA.
Logistics are typically FOB China port, with containerized shipments preferred. Lead time is not stated but typically ranges from 15 to 30 days after order confirmation, depending on production scheduling. Payment terms are commonly 30% advance, 70% against BL copy. Incoterms should be clearly defined; avoid CFR or CIF unless the buyer controls insurance. Confirm that packaging is moisture-sealed and labeled in English with hazard class UN 3077.
Perform a physical inspection upon arrival for signs of moisture damage, clumping, or discoloration. Conduct a simple solubility test: 10g in 100ml water should dissolve completely with no residue. Test pH with a calibrated meter. Retain a 500g sample for 60 days in case of quality disputes. Request the supplier to provide a Material Safety Data Sheet compliant with GHS standards. Documentation must include the batch number, production date, and test results for all critical parameters.
