Full Description

Hydrochloric acid (HCl, CAS 7647-01-0), sold technically as muriatic acid, is an aqueous solution of hydrogen chloride. It is used for metal pickling and surface cleaning, electroplating, ore and oil-well acidizing, pH neutralization, and as a feedstock for producing chlorides and other chemicals.

Frequently Asked Questions

What is hydrochloric acid used for?

Hydrochloric acid (HCl, CAS 7647-01-0), sold technically as muriatic acid, is an aqueous solution of hydrogen chloride. Industrial uses include metal pickling and surface cleaning, electroplating prep, oil-well acidizing and stimulation, pH neutralization of alkaline streams, ore leaching, and as a feedstock for producing chlorides and other chemicals.

What concentrations of hydrochloric acid are available in bulk?

HCl is commonly supplied in technical grades such as approximately 31–37% (muriatic) as well as lower dilutions for pH control. Specify your required concentration and grade when requesting a quote; the CoA confirms the lot assay.

What is the UN number and DOT shipping classification for hydrochloric acid?

Hydrochloric acid solution ships under UN 1789 (HYDROCHLORIC ACID, SOLUTION). Packaging, labeling, and carrier requirements follow the SDS and applicable transport regulations — RawSource provides the SDS and shipping documentation with every order.

What is the HS code for hydrochloric acid?

It classifies under HS 2806.10 (hydrogen chloride / hydrochloric acid). Confirm destination-country tariff treatment with your customs broker; commercial and transport documents accompany each shipment.

What bulk packaging is available for hydrochloric acid?

HCl is supplied in drums, IBC totes, and bulk for industrial users. MOQ, lead time, and pricing are quote-based — request a bulk quote with your target concentration and volume; an SDS and CoA accompany the order.
