Product classification
HS code for Muriatic acid: 2806.10
Hydrogen chloride (hydrochloric acid).
Classification of muriatic acid under HS 2806.10
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.

Codes often confused with 2806.10
Common mistake. 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.
Top exporters and importers of HS 280610 (the code used for muriatic acid), 2025
In 2025, the largest exporter of HS 280610 (the code used for muriatic acid) in UN Comtrade data was Germany, with 16% of world exports; the largest importer in UN Comtrade data was the United States, with 16% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).

Questions about muriatic acid
What is the HS code for Muriatic acid?
The HS code for Muriatic acid is 280610 (Hydrogen chloride (hydrochloric acid)). The HS code for muriatic acid (hydrochloric acid) is 2806.10.
How do I classify Muriatic acid for customs?
Muriatic acid is classified under HS code 280610 — Hydrogen chloride (hydrochloric acid). This is a 6-digit subheading level code.
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.
Which countries are the top exporters of muriatic acid (HS 280610)?
In 2025, the top exporters of HS 280610 (the code used for muriatic acid) in UN Comtrade data were Germany ($66M, 16% of world exports), Canada ($57M) and Japan ($33M). World exports came to about $410M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Which countries are the top importers of muriatic acid (HS 280610)?
In 2025, the top importers of HS 280610 (the code used for muriatic acid) in UN Comtrade data were the United States ($70M, 16% of world imports), France ($50M) and Germany ($25M). World imports came to about $444M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Is the HS code for Muriatic acid the same in all countries?
The base HS code 280610 for Muriatic acid is internationally standardized for the first 6 digits across 200+ countries. Individual countries may add additional digits for national tariff lines and specific classifications.
What is the NCM code for muriatic acid in Brazil?
Brazil splits HS 280610 into 2 NCM codes, so the right one for muriatic acid depends on the product's details: 2806.10.10 (Hydrogen chloride, gaseous or liquefied), 2806.10.20 (Hydrochloric acid in aqueous solution).
