What is the correct HS code for hydrochloric acid?
Match the product to the legal wording, then verify the final pick in your country tariff schedule before filing.
HS-4 · Heading
2806 — Hydrogen chloride (hydrochloric acid); chlorosulphuric acid
Chapter 28: Inorganic chemicals
Plain-language overview
Use HS-4 2806 when importing hydrogen chloride (hydrochloric acid) or chlorosulphuric acid. For example, if you're bringing in a bulk shipment of hydrochloric acid for industrial cleaning or pH adjustment in water treatment, this is the correct code.
The distinction between HS-6 280610 and HS-6 280620 is crucial. If your product is pure hydrogen chloride, use 280610. However, if you have chlorosulphuric acid, which contains both chlorine and sulfur, you should classify it under 280620. Knowing the exact chemical composition will guide your classification.
When assessing your product, consider the end-use and concentration. For instance, a solution containing 30% hydrochloric acid is still classified under 280610, while a more complex acid like chlorosulphuric acid should be reported under 280620. Misclassification can lead to delays or penalties.
