Potassium phosphate dibasic

Potassium Phosphate Dibasic (K2HPO4) is a highly versatile chemical used across multiple sectors. In the food industry, it acts as a buffering agent, emulsifier, and stabilizer, commonly found in non-dairy creamers and electrolyte drinks. In agriculture, it serves as a high-efficiency liquid fertilizer due to its high solubility. For laboratory and pharmaceutical use, it is critical for pH control in culture media and as a buffering reagent in drug formulation.

Buyers must distinguish between Food Grade, Pharmaceutical Grade, and Technical Grade. Key parameters include Purity (typically ≥98%), pH value (8.7–9.3 in a 5% solution), and Heavy Metal content (Lead <2ppm, Arsenic <3ppm) for food-grade applications. Additionally, check the Loss on Drying specs, as this chemical is hygroscopic and can cake if moisture levels exceed 2.0%.

For food-grade exports, the product must comply with FCC (Food Chemicals Codex) or E340(ii) standards. Pharmaceutical applications require adherence to USP/BP/EP (United States, British, or European Pharmacopoeia). Ensure the supplier provides a COA (Certificate of Analysis) and MSDS (Material Safety Data Sheet). For European markets, REACH registration is essential for chemical substances.

Since Potassium Phosphate Dibasic is deliquescent (absorbs moisture from air), it must be stored in cool, dry, and well-ventilated areas. Ensure the supplier uses double-layered packaging, typically a PE (Polyethylene) inner bag sealed inside a PP (Polypropylene) woven bag or fiber drum to prevent clumping and chemical degradation during transit.

While not classified as a hazardous 'dangerous good' by most maritime codes, it is a chemical powder, which often triggers stringent customs inspections. Buyers should ensure the supplier provides a 'Certification for Safe Transport of Chemical Goods' to avoid port delays. Failure to declare the correct HS Code (typically 283524) can lead to customs seizures or incorrect tariff applications.

When negotiating, request a pre-shipment inspection (PSI) by third parties like SGS or Intertek to verify that the chemical purity matches the sample. Always clarify Incoterms; for chemicals, CIF (Cost, Insurance, and Freight) is often preferred by new buyers to ensure the seller handles the complex export logistics.

The chemical market is sensitive to raw material costs (phosphoric acid and potassium hydroxide). It is recommended to sign annual framework agreements with verified manufacturers to lock in prices. For cross-border logistics, allow a buffer of 10-15 days beyond the standard 20-day production lead time to account for ocean freight congestion and export clearance procedures.
