Import Disodium Phosphate — Buy in Bulk from Supplier in China

Disodium phosphate (Na2HPO4·12H2O) is a white to colorless crystalline powder with a molecular weight of 358.14 g/mol, supplied as a hydrated salt. It is highly soluble in water and exhibits strong buffering capacity in the pH range of 8.0 to 9.2, making it suitable for applications requiring precise pH control. The compound is delivered as a free-flowing powder with low bulk density, typical of food-grade phosphates, and shows no visible impurities under standard lighting conditions.

This grade of disodium phosphate meets standard food and industrial specifications for purity, with typical heavy metal limits below 10 ppm and moisture content under 15%. The anhydrous equivalent is approximately 62% by weight, consistent with industry norms for dodecahydrate forms. It does not contain added anti-caking agents, and its solubility profile aligns with USP and FCC standards for phosphate buffers. Variants may differ slightly in crystal structure depending on drying conditions, but the active ingredient remains unchanged.

It is primarily purchased by food manufacturers for use in cheese processing, baked goods, and processed meats as a pH regulator and emulsifier. Pharmaceutical formulators use it to stabilize injectable solutions, while agricultural suppliers blend it into foliar nutrients for phosphorus delivery. Buyers typically order in 25 kg polypropylene bags with inner liners, with MOQs negotiable based on volume. Lead times are generally 15 to 25 days after payment confirmation, with FOB Shanghai or CIF terms available upon request.

Sichuan Xingbaisheng Chemical Co., Ltd. operates from Shigu Town in Shifang, Deyang, Sichuan Province, China. The supplier is verified as an importer with harbor-level trust signals, indicating active customs documentation and export experience. There is no public information on production capacity, years in operation, or staff size. The listing confirms no direct manufacturing capability; the company sources and exports the product under its own label.

The supplier does not claim ISO, SGS, or other certifications in its profile, and response metrics show no recorded communication activity. Buyers should treat this as a trading entity rather than a producer. The company's operational focus appears limited to bulk export of industrial chemicals, with no evidence of R&D, lab testing, or private formulation services.
