Overview
This HTS category, 3102.40.00.00, encompasses mixtures where ammonium nitrate is combined with inorganic non-fertilizing substances, most commonly calcium carbonate. The primary purpose of these mixtures is still for fertilization, but the addition of substances like calcium carbonate serves to improve the handling properties, reduce the risk of explosion, or modify the release rate of the nitrogenous component. These are distinct from pure ammonium nitrate (3102.30.00.00), which is classified separately, and from urea (3102.10.00), another major nitrogenous fertilizer.
Unlike some sibling categories that focus on single compounds or specific double salts, 3102.40.00.00 specifically addresses mixtures designed for agricultural use. The key defining characteristic is the presence of ammonium nitrate as a primary component, blended with inert or non-fertilizing inorganic materials. This ensures that goods primarily composed of ammonium nitrate with other fertilizing components, or solely ammonium nitrate itself, are classified under different headings.
As this is a leaf node within the HTS structure, there are no further subdivisions under 3102.40.00.00. Classification within this category is determined by the confirmed presence of ammonium nitrate in combination with non-fertilizing inorganic substances. Importers should ensure that the composition of the product aligns with the description to maintain accurate customs declarations.
