This is the technical grade of ammonium sulfate, refined to 99% assay with iron held under 30 ppm and insolubles under 0.05%. In industrial work those two figures decide whether a batch disappears into a formulation or leaves a mark on it. The material serves as the ammonium and sulfur source in flame retardant systems, as an auxiliary in textile dyeing and leather processing, as the ammonium feed for chloramine disinfection, and as the starting material for ammonium persulfate.
Technical Advantages
Stable Chemical Property
Ammonium sulphate features high sulfur content and stable chemical properties. It dissolves easily and delivers consistent reaction results for textile, leather and water treatment processes.
Excellent Cost Performance
Compared with many other ammonium salts, it has obvious cost advantages. It helps cut raw material costs for industrial production while maintaining reliable performance.
Low Impurity Content
Industrial grade ammonium sulphate contains low water-insoluble substances. Its quality meets the standards for analytical reagents, electroplating and pharmaceutical auxiliary materials.
Wide Application Range
It serves multiple purposes including dyeing auxiliary, flame retardant, tanning agent and water purifying agent. One raw material fits different industrial scenarios.

FAQ
Q: What separates this grade from the fertilizer grade?
A: The refining. Iron, chloride, and insolubles are held to a fraction of the fertilizer figures, which is what industrial formulations pay for.
Q: Will the iron content show up in a white or pastel dyed fabric?
A: Not at 30 ppm maximum. Iron is the usual cause of dulled shades and rust spotting, and this level sits well below where that begins.
Q: How do I stop it caking in a humid plant?
A: Keep bags sealed and off the floor, and reseal after each charge. If your plant runs above 70% relative humidity year round, ask about drum packing before ordering.
Q: Can it be used for chloramine dosing in drinking water?
A: Yes, it is a standard ammonium source for that duty. Confirm the local dosing limit and permit requirements with your authority before you commit to a specification.
Q: What is the lead time and minimum order?
A: One 20' container of about 25 tons, shipping in 7 to 12 days from stock. Tighter specifications are scheduled around the production run.
