HS Code for Muriatic acid

Muriatic acid is the common industrial name for hydrochloric acid, and it is classified under HS code 2806.10. This code is located in Chapter 28, which encompasses inorganic chemicals and precious metal compounds. Heading 2806 specifically covers hydrogen chloride (hydrochloric acid) and chlorosulphuric acid. Muriatic acid is typically an aqueous solution of hydrogen chloride gas. The classification remains consistent regardless of the concentration of the acid, provided it is not mixed with other chemicals that would change its essential character into a prepared chemical mixture. As a strong mineral acid, it is used in various applications, from pH adjustment in swimming pools and water treatment to metal pickling, ore processing, and chemical synthesis. Accurate classification is vital due to the hazardous nature of the substance, which triggers specific regulatory requirements for transport, safety data sheets (SDS), and environmental handling. Customs officials verify the chemical composition to ensure it meets the criteria for hydrogen chloride under the inorganic chemical chapter.

Products Included

Common Misclassification

Muriatic acid is sometimes misclassified under HS code 2807.00, which is reserved for sulphuric acid and oleum. It may also be confused with HS code 3824, which covers prepared binders for foundry moulds or chemical products and preparations of the chemical or allied industries not elsewhere specified. This happens when the acid is part of a proprietary cleaning mixture rather than a pure aqueous solution.

FAQ

What is the HS code for Muriatic acid?

The HS code for muriatic acid (hydrochloric acid) is 2806.10.

Does the concentration of the acid change the HS code?

No, varying concentrations of hydrochloric acid in water are still classified under 2806.10, provided no other substances are added that change its chemical nature.
