3% Hydrochloric Acid (CAS No.: 7647-01-0), chemically known as aqueous hydrogen chloride (HCl), is a colorless to light yellow transparent liquid with a pungent odor, strong acidity, and excellent solubility. As a critical basic chemical, it is widely used in industrial cleaning, metallurgy, chemical synthesis, and water treatment. Our 33% hydrochloric acid is produced via the advanced “chlorine-hydrogen combustion” process at state-of-the-art facilities in China’s key chemical clusters (Shandong, Jiangsu, Tianjin), using high-purity chlorine (Cl₂) and hydrogen (H₂) as raw materials—ensuring consistent concentration and low impurity levels.​

With a fixed concentration of 33% (w/w, customizable ±2% per request), our product meets stringent international standards (GB/T 320-2023, ASTM D1141-18, ISO 7627-1:1990). Key quality indicators are rigorously controlled: iron (Fe) ≤ 0.001%, arsenic (As) ≤ 0.0001%, heavy metals (Pb/Cd) ≤ 0.0005%, free chlorine ≤ 0.005%, and residue on ignition ≤ 0.005%. It is free from harmful contaminants and organic impurities, ensuring safe and stable performance across industrial processes. As a leading Chinese supplier, we leverage China’s mature chlor-alkali industry chain, large-scale production capacity, and cost advantages to deliver high-quality 33% hydrochloric acid to global customers.​
