Our high-purity Oxalic Acid is premium white crystalline organic chemical with ISO 9001 certification and full SGS quality compliance. Strict impurity control limits chloride, calcium and iron content to maximum 0.0005% separately, with ignition residue below 0.01%, delivering ultra-clean, stable neutral-grade raw material with uniform fine crystal appearance.
 
This eco-friendly multifunctional reagent boasts powerful chelating, rust-removing and reducing capacity. It is widely applied in metal surface derusting, industrial equipment descaling, water treatment formulations, textile bleaching, printing and dyeing reduction processes. It efficiently eliminates mineral stains, limescale and metal oxides with fast reaction speed and lower consumption than ordinary cleaning agents.
 
Each batch is sealed in 25kg moisture-proof PP woven bags lined with plastic film to prevent caking during transit and storage. Featuring reliable consistent purity, low heavy metal impurities and wide industrial adaptability, our oxalic acid serves as cost-effective, high-performance raw material for cleaning, textile, water treatment and metal processing industries worldwide.
