3105.59.00.00 - Other

This HTS category, 3105.59.00.00, encompasses "other" mineral or chemical fertilizers that contain both the fertilizing elements nitrogen and phosphorus, but do not fall under the specific subheading for those containing nitrates and phosphates. These fertilizers are distinct from those containing solely nitrogen and phosphorus in nitrate forms, as well as from other categories within Chapter 31 which may contain different combinations of fertilizing elements or lack specific forms.

The key differentiator for this category lies in its exclusion of fertilizers where the phosphorus component is primarily in the form of phosphates and the nitrogen component is primarily in the form of nitrates. Therefore, fertilizers falling under 3105.59.00.00 would include nitrogen and phosphorus fertilizers where the phosphorus is present in forms other than standard phosphates, or where the nitrogen is in forms other than nitrates, or a combination of such differing compositions.

As this is a leaf node, there are no further subcategories. Classification under this specific HTS code hinges on identifying fertilizers that contain both nitrogen and phosphorus and carefully ruling out the more specific classification for those containing nitrates and phosphates. The absence of further subdivisions means that all goods meeting the primary criteria and not specified elsewhere within 3105.51.00.00 will be classified here.
