Import Disodium Phosphate — Buy in Bulk from Supplier in China

Disodium phosphate is supplied in three hydrated forms: anhydrous (Na2HPO4), dihydrate (Na2HPO4·2H2O), and dodecahydrate (Na2HPO4·12H2O), each with distinct molecular weights of 141.96, 177.99, and 358.14 g/mol respectively. The compound appears as white or colorless orthorhombic or monoclinic crystals, highly soluble in water but insoluble in ethanol, with a relative density of 1.52 and a melting point of 34.6°C. At 180°C, the hydrated forms lose water and convert to the anhydrous state, a behavior critical for industrial processing. The CAS numbers for each form are provided: 7558-79-4 for anhydrous, 10028-24-7 for dihydrate, and 10039-32-4 for dodecahydrate.

This material is manufactured under food-grade standards, with packaging consisting of an inner polyethylene liner and an outer composite plastic woven bag, each weighing 25 kg net. The product is stable under dry, ventilated storage conditions and must be kept isolated from toxic or corrosive substances to prevent contamination. Moisture exposure can cause caking or degradation, so humidity control is essential during storage. The supplier does not claim certification to ISO or HACCP, but the formulation aligns with typical food additive specifications used in processed food manufacturing.

Disodium phosphate is primarily used in bakery products to regulate pH, prevent oxidative discoloration, and improve dough consistency. It acts as an emulsifier in dairy applications, prevents protein coagulation in processed cheeses, and serves as a chelating and buffering agent in solid beverage mixes. Buyers include food manufacturers of dairy alternatives, bakery chains, and beverage powder producers. Trade is conducted FOB Lianyungang Port, with bulk shipments typically in 20-foot containers holding 20 metric tons. Lead time is not stated and must be confirmed directly with the supplier.

Lianyungang Longtaiwei Food Ingredients Co., Ltd is based in the Guannan Economic Development Zone of Lianyungang City, Jiangsu Province, China. The company operates from a facility located at Longtaiwei Road No. 1, with direct access to the Port of Lianyungang for export logistics. The listing confirms the supplier's physical address and product packaging details but provides no information on company history, employee count, revenue, or client list. Response rate and average response time are not tracked in the system, indicating limited buyer engagement capability.

The supplier specializes in food-grade phosphate compounds, with disodium phosphate as a core offering. No third-party certifications such as ISO 22000, HACCP, or FDA registration are mentioned in the listing. The facility appears to be a manufacturer or bulk packager, given the specificity of packaging and storage instructions. The absence of verified buyer reviews or export documentation details suggests the supplier may be a smaller or newer participant in international trade. Buyers should request independent lab reports before placing bulk orders.
