We are one of the leading manufacturers, distributors, and suppliers of Sulfamic acid in USA. Its CAS Number is 5329-14-6, and the chemical formula is H3NO3S.
Sulfamic acid, also known as Amidosulfonic acid, with the chemical formula (H₃NSO₃), is a white crystalline solid known for its strong cleaning, descaling, and chemical reactivity properties. It is odorless and soluble in water. The molar mass of sulfamic acid at 97.09 g/mol makes it particularly efficient for industrial applications, as relatively small quantities can achieve significant chemical reactions. As a trusted manufacturer and supplier of sulfamic acid in the USA, we provide high-purity (99.95%) sulfamic acid crystals that ensure consistent quality. Sulfamic acid is essential for applications in water treatment, metal cleaning, dye production, and paper bleaching, adhering to strict U.S. standards. Our product has TSCA and NSF certifications. We also provide the necessary documentation, including the SDS/MSDS for sulfamic acid and the COA. Our sulfamic acid price (USD) is competitive and varies depending on order volume, packaging, and delivery terms (FOB or CIF). Sulfamic acid crystals are available in small and bulk packaging that includes 2.2 lb, 11 lb, 22 lb, and 55 lb bags.

Water treatment plants use sulfamic acid procured from reputed sulfamic acid suppliers to formulate acid-based descalers for boilers, heat exchangers, and pipelines. It effectively removes limescale, rust, and hard water deposits.
Sulfamic acid is applied as a bleaching agent and pH stabilizer in the pulp and paper industry. It prevents over-acidification, enhances whiteness, and improves chemical efficiency
Sulfamic acid plays a vital role in chemical synthesis. It acts as a sulfonating agent in organic reactions and is involved in producing intermediates for herbicides, sweeteners, and API molecules.
In the metal finishing and automotive sectors, sulfamic acid is widely used for pre-cleaning of metals before plating and rust removal from stainless steel, copper, and aluminum.
The high-purity grades produced by specialized sulfamic acid manufacturers serve critical roles in circuit board etching processes and semiconductor wafer cleaning.
