Import Ammonium Sulphate Cp Grade — Buy in wholesale FOB from Supplier in China

Ammonium Sulphate CP Grade from Nanjing Jiayi Sunway Chemical Co., Ltd. is a chemical pure grade industrial compound with molecular formula (NH4)2SO4 and CAS number 7783-20-2. The material presents as colorless or white crystals or granules with no odor, meeting stringent purity standards for laboratory and industrial processes where contaminant levels must be tightly controlled. This grade sits above technical or fertilizer grades in purity hierarchy, making it suitable for analytical applications and precision chemical synthesis where trace impurities could compromise reactions or measurements.

The product consists of ammonium sulphate with a nitrogen content typically around 21% by mass, though buyers should request a current certificate of analysis for the specific batch. CP grade generally specifies limits on chloride, heavy metals, iron, and residue on ignition that exceed reagent grade specifications but remain tighter than agricultural fertilizer standards. In crystalline form, the material offers excellent solubility in water (approximately 70.6 g per 100 mL at 20 degrees C), a property exploited in both solution preparation and crystallisation-based purification processes. Standard packaging for this grade typically involves multi-layer moisture-resistant bags, often 25 kg or 50 kg, to prevent caking during storage.

Primary buyers include pharmaceutical manufacturers, analytical laboratories, electronics plating operations, and chemical synthesis facilities requiring consistent, documented purity. The compound serves as a nitrogen source in nutrient media, a precipitating agent in protein purification, and a raw material in flame retardant and food additive production. For import buyers, this listing originates from Nanjing in Jiangsu province, a major Chinese chemical manufacturing cluster with established logistics infrastructure. Confirm directly with Nanjing Jiayi Sunway Chemical Co., Ltd. regarding current MOQ, Incoterms, lead times, and whether they provide supporting documents such as SDS, COA, or third-party test reports, as these operational details are not specified in the available data.

Nanjing Jiayi Sunway Chemical Co., Ltd. is located at No.100 Qinhuai Road, Nanjing, Jiangsu, 211100, China, placing it in one of the country's established chemical manufacturing and distribution corridors. The supplier holds a harbor trust tier and shows a 0.00% response rate with zero average response hours recorded in the available data, which raises questions about current operational status that prospective buyers should investigate directly before committing to orders. No verified certifications, years in business, factory size, or client references are stated in the profile, so claims about ISO compliance or similar credentials cannot be confirmed from this listing alone.

The company trades Ammonium Sulphate CP Grade as a bulk industrial chemical, positioning it within the fertilizer and fine chemical supply chain. Buyers should note that the listing description mentions ISO and SGS certifications in generic terms, but these are not confirmed as held by this specific supplier in the provided data. The Jiangsu location offers proximity to Shanghai Port for export logistics, though actual shipping arrangements, Incoterms, and packaging customisation must be negotiated directly. Given the absence of response data, initiating contact through multiple channels and requesting recent COA, SDS, and business registration documents would be prudent due diligence steps.
