About Hydrochloric Acid (Muriatic)

Buy hydrochloric acid (HCl, CAS 7647-01-0), also known as muriatic acid, from Alliance Chemical in 5%-37% concentrations. This collection includes Technical and ACS grades for pH adjustment, metal cleaning, scale removal, oilfield use, and laboratory reagent work.

Products In This Collection

This collection includes dilute HCl for controlled cleaning and pH adjustment, mid-strength concentrations for process use, and 31%-37% products for industrial and laboratory applications. ACS grades are selected for reagent work, while Technical Grade supports production and maintenance needs.

Common Applications

  • Metal cleaning and pickling: Hydrochloric acid removes scale, rust, and oxide layers from compatible metal surfaces before finishing or processing.
  • pH adjustment: Water treatment and industrial processes use HCl to lower pH when the chloride load is acceptable for the system.
  • Concrete, stone, and scale removal: Dilute muriatic acid is used for mineral scale and masonry cleaning where surface compatibility is confirmed.
  • Laboratory reagent use: ACS hydrochloric acid supports digestion, sample preparation, and acid-base chemistry where reagent grade is required.

Grade & Selection Notes

Choose dilute grades when control and lower fume generation matter. Choose 31%-37% HCl only when your process requires concentrated acid and your site is prepared for corrosive vapor handling.

Safety & Handling

Hydrochloric acid is corrosive and can release irritating hydrogen chloride vapors. Use acid-resistant PPE and ventilation. Never mix hydrochloric acid with bleach, hypochlorite, or other oxidizers. Review the Safety Data Sheets before use and follow your site-specific handling procedure.

Why Buy From Alliance Chemical

Most in-stock HCl orders ship in 1-2 business days with SDS availability and lot-specific COA support. As a bulk hydrochloric acid distributor, Alliance Chemical fills wholesale, multi-drum, and recurring HCl orders as well as single quarts, with volume pricing on request.

Frequently Asked Questions

Where can I buy hydrochloric acid?
Right here. Alliance stocks hydrochloric acid from 5% to 37% in technical and ACS reagent grades, in 1 quart, 1 gallon, 5, 15 and 55 gallon drums and 275 and 330 gallon totes. Ships from Texas in 1 to 2 business days with the SDS on every product page.
Which hydrochloric acid strength should I buy?
37% is full strength for processing and labs; 31% is muriatic-acid strength for masonry, concrete and pool work; 15% is a ready working strength for descaling and pH adjustment; 5% and 10% for gentle cleaning and teaching labs.
Can I buy hydrochloric acid in bulk?
Yes. 55-gallon drums and 275-gallon and 330-gallon totes ship on a pallet by LTL freight. For multi-drum or recurring supply, use the quote form on any product page and we price it with freight.
Who can buy hydrochloric acid?
Anyone. Alliance sells hydrochloric (muriatic) acid, 5% to 37%, online to businesses and individuals, quart through tote. It is a DEA List II chemical, but DEA excludes domestic sales from regulated transactions, so U.S. buyers need no license and DEA requires no purchase record. Its 50-gallon threshold applies only to exports to 14 Latin American countries.
How is hydrochloric acid shipped?
Every strength ships as UN1789, Hydrochloric acid, Class 8, Packing Group II (5%: PG III), packed by staff trained to 49 CFR 172.704. Quarts, and 5% gallons, ship UPS Ground as Limited Quantity, other gallons and pails as regulated hazmat by UPS Ground, drums and totes by LTL freight.
Which hydrochloric acid concentration should I choose?
Choose the lowest concentration that meets your process requirement. Dilute grades are used where controlled pH adjustment or lower fume generation matters, while 31% and 37% HCl are selected for applications that require concentrated acid and appropriate corrosive-vapor controls.
What is the difference between ACS and Technical Grade hydrochloric acid?
ACS Reagent Grade is intended for laboratory and analytical work where tighter impurity specifications are required. Technical Grade is commonly used for industrial cleaning, metal processing, pH adjustment, and other production applications. Review the product specification and lot-specific COA against your process requirements.
Do hydrochloric acid orders include SDS and COA documentation?
Safety Data Sheets are available for all hydrochloric acid products. Alliance Chemical also provides lot-specific Certificate of Analysis support; confirm the documentation requirements for your grade and application before ordering.
Can hydrochloric acid be used for metal cleaning or pH adjustment?
Hydrochloric acid is used in compatible metal cleaning, scale removal, and pH adjustment processes. Suitability depends on the material, chloride tolerance, concentration, ventilation, and site procedure. Review the SDS and validate compatibility before use.
