Import Diammonium Phosphate Ammonium Phosphate Dap — Buy in wholesale FOB from Supplier in China

Diammonium phosphate (DAP) from Sichuan Bangyuan Technology Co., Ltd. is a white crystalline compound with the chemical formula (NH4)2HPO4 and a molecular weight of 132.0 g/mol. It has a density of 1.619 g/cm³, melts at 155°C, and is highly soluble in water but insoluble in alcohol. The product meets the HG/T4132-2010 industrial standard and achieves 99% purity, with a 1% aqueous solution pH of 8.0. It is supplied in palletized form as per buyer requirements and has a shelf life of two years when stored in dry, cool conditions.

This DAP grade is produced for industrial applications, not food use, and differs from food-grade DAP governed by GB 30613-2014. The material is crystalline with low moisture content and minimal foreign matter, typical of industrial-grade DAP. It does not contain additives or anti-caking agents. The supplier does not confirm certification to ISO or other international standards, and the product is not labeled for agricultural use despite common industry overlap.

Primary applications include ABC dry chemical fire extinguisher formulations, where DAP constitutes over 75% of the active ingredient, acting as a flame inhibitor by interrupting combustion radicals and forming a protective char layer. It is also used as a fire retardant for textiles, timber, and paper, and as a dispersant in dye and fiber processing. Buyers typically source this material for industrial fire safety manufacturers and chemical compound formulators. Trade terms are FOB China port, packaging is bulk or palletized, and MOQ is confirmed only upon direct inquiry.

Sichuan Bangyuan Technology Co., Ltd. is based in Mianzhu, Sichuan Province, China, with a registered address in Anguo New District. The company operates as a chemical supplier with no public information on production capacity, workforce size, or export history. Its trust tier is listed as harbor, indicating basic verification of legal registration. There is no data on certifications, third-party audits, or client references. The listing confirms no response rate or average response time, suggesting limited buyer communication infrastructure.

The company does not claim to be a manufacturer, and the source material does not indicate ownership of a production facility. It may act as a trader or distributor sourcing DAP from regional producers. No information is provided about quality control procedures, lab testing capabilities, or packaging customization beyond palletization. Buyers should treat this supplier as a sourcing agent and verify all technical claims directly before order placement.
