2814.20.00.00 - Ammonia in aqueous solution

This HTS category, 2814.20.00.00, specifically classifies ammonia when it is presented in an aqueous solution. This means the ammonia is dissolved in water. It encompasses a wide range of products where ammonia is the primary active component and is delivered in a liquid form containing water. Examples include household ammonia cleaners, laboratory reagents that are aqueous ammonia solutions, and industrial process chemicals where ammonia is used in a water-based form.

It is crucial to distinguish this category from its sibling, 2814.10.00.00, which covers anhydrous ammonia. Anhydrous ammonia is ammonia in its pure gaseous or liquid form, without the presence of water. The defining characteristic for this category is the presence of water as a solvent for the ammonia, significantly altering its physical properties and handling requirements compared to anhydrous ammonia.

As a leaf node, this category does not have further subdivisions. Therefore, classification within 2814.20.00.00 relies solely on the definitive presence of ammonia dissolved in water. Any product meeting this criterion, regardless of concentration (within reasonable limits for a functional aqueous solution), and not otherwise specifically excluded or classified elsewhere, will fall under this heading. The concentration of ammonia in water can be a factor in determining its end-use and specific application, but the fundamental classification hinges on its dissolved state in an aqueous medium.
