Frequently Asked Questions
What is the full form of HCl — and is muriatic acid the same as hydrochloric acid?
HCl is the chemical formula and short form of hydrochloric acid (CAS 7647-01-0). Muriatic acid is simply the older trade name for the same chemical — hydrochloric acid and muriatic acid are one and the same substance.
What is the CAS number and HSN code of hydrochloric acid?
Hydrochloric acid has CAS number 7647-01-0 and HSN code 2806 10 00. For transport it is classified UN 1789, Hazard Class 8 (Corrosive), Packing Group II.
What grades of hydrochloric acid do you supply — 30%, 33% or 35%?
We supply three grades: Commercial (30%), Technical (33%) and Synthetic (35%). Our commercial grade conforms to IS 265:1995 (RA2015) and is sourced from an ISO 9001 / ISO 14001 certified manufacturer — the manufacturer's analytical report on a recent lot recorded 32.50% total acidity (as HCl).
What is hydrochloric acid used for?
Hydrochloric acid is widely used for steel pickling and metal cleaning, pH control in water treatment, ore processing, and the production of chlorides and other chemical intermediates. We supply it to industrial buyers across South India in carboy, barrel, IBC and bulk tanker quantities.
Can I buy hydrochloric acid in bulk in Chennai?
Yes. We stock hydrochloric acid at our Redhills, Chennai warehouse and dispatch across South India in 35 kg HDPE carboys, 200 L HDPE barrels, 1000 L HDPE IBCs and bulk rubber-lined tankers, typically ex-stock to 2 working days. Order sizes depend on packaging and current stock — call or WhatsApp +91 86087 80096 for a quote.
How should hydrochloric acid be stored?
Store hydrochloric acid in HDPE, FRP or rubber-lined containers in a cool, well-ventilated area, away from metals and alkalis. It is corrosive to skin, eyes and the respiratory tract and emits irritating fumes, so acid-resistant PPE is essential. Shelf life is 12 months from manufacture.
