HS Code for Ammonium hydroxide

Ammonium hydroxide, commonly known as aqueous ammonia or ammonia water, is classified under HS code 2814.20. This code specifically covers "Ammonia in aqueous solution." It falls under heading 2814, which includes ammonia, whether anhydrous or in aqueous solution. The distinction between the two subheadings in 2814 is based entirely on the physical state and the presence of water as a solvent. Anhydrous ammonia, which is ammonia gas or liquefied ammonia without water, is classified under 2814.10. Ammonium hydroxide is a solution of ammonia in water and is a vital industrial chemical used in the production of fertilizers, explosives, plastics, and various cleaning agents. The classification remains 2814.20 regardless of the concentration of the ammonia in the water, provided it is a simple solution. It is important to distinguish this bulk chemical from prepared cleaning products. If ammonium hydroxide is mixed with surfactants, perfumes, or other additives and packaged for retail sale as a household cleaner, it would be classified under heading 3402. However, the pure aqueous solution used for industrial or laboratory purposes is strictly 2814.20.

Products Included

• Aqueous ammonia solution
• Ammonia water
• Household ammonia (if not containing other detergents)
• Technical grade ammonium hydroxide
• Reagent grade ammonium hydroxide

Common Misclassification

The most common misclassification is using HS code 2814.10, which is only for anhydrous ammonia. Another frequent error is classifying industrial ammonium hydroxide under 3824.99 (miscellaneous chemical products) or 3402.90 (cleaning preparations). If the product is simply ammonia dissolved in water, 2814.20 is the only appropriate code.

FAQ

What is the HS code for Ammonium hydroxide?

The HS code for ammonium hydroxide (ammonia in aqueous solution) is 2814.20.

Does the concentration of the solution change the HS code?

No, as long as it is a solution of ammonia in water, it is classified under 2814.20 regardless of the concentration percentage.
