Import Ammonium Chloride — Buy in Bulk from Supplier in China

Ammonium chloride from Weifang Doze Chemtech Co., Ltd is a white crystalline powder or granule with the chemical formula NH4Cl and CAS number 12125-02-9. The product meets the GB/T 7118-2008 standard and is supplied at a minimum purity of 99.5%, with moisture content capped at 0.5% and residue on ignition at 0.4%. It is odorless, with a salty and cool taste, and is soluble in water, glycerol, and ammonia but insoluble in ethanol, acetone, and ethyl acetate. The material has a melting point of 340°C (sublimes), a density of 1.52 g/cm³, and a pH of 4.7 in a 200 g/l aqueous solution at 25°C.

This grade is produced to precise specifications, with heavy metal (Pb) content limited to 0.0005%, ensuring suitability for industrial and reagent applications. Ammonium chloride is commonly used as a flux in metalworking, a component in dry batteries, and a source of nitrogen in fertilizers. Its weak acidic nature in aqueous solution and sublimation behavior at elevated temperatures are key to its performance in these applications. Typical industry use also includes pharmaceuticals and food additives, where purity and low heavy metal content are critical.

Primary buyers include chemical manufacturers, agrochemical producers, and metal processing plants. The product is packaged for bulk shipment, with stability ensured under dry conditions to prevent caking. Buyers should confirm packaging type, shelf life, and storage recommendations with the supplier. Lead times and incoterms are negotiable, with FOB or CFR terms common for exports from Shandong’s ports.

Weifang Doze Chemtech Co., Ltd is based in Shouguang City, Shandong Province, China, a region known for its chemical manufacturing hubs. The company operates from an address at South of Xingan Road, with a postal code of 262700. Its profile indicates a focus on chemical production, with ammonium chloride as one of its key offerings.

The supplier holds a harbor trust tier, though its response rate and average response hours are currently listed as zero. This suggests that direct contact may require persistence, but the address and regional reputation provide a foundation for verification. The company’s listing does not state certifications, production capacity, or export history, so buyers should confirm these details through direct inquiry.
