Overview

This HTS classification, 3105.60.00.00, specifically covers mineral or chemical fertilizers that contain exactly two of the three primary fertilizing elements: phosphorus and potassium. These fertilizers are characterized by the presence of these two nutrients, without the inclusion of nitrogen. They are intended for agricultural or horticultural use to enrich soil and promote plant growth by providing essential phosphorus and potassium.

To differentiate this category from its siblings, it is crucial to note the exclusion of nitrogen. For example, HTS 3105.20.00.00 covers fertilizers containing all three elements (nitrogen, phosphorus, and potassium), while other sibling categories like 3105.30.00.00 and 3105.40.00 detail specific diammonium and monoammonium phosphate compounds, which inherently include nitrogen. This category focuses solely on the binary combination of phosphorus and potassium.

As a leaf node in the HTS structure, HTS 3105.60.00.00 does not have further subdivisions. Therefore, classification within this code hinges on the confirmed presence of both phosphorus and potassium as the sole fertilizing elements, to the exclusion of nitrogen. Examples of such products might include mixtures of potassium phosphates or certain blended mineral salts where nitrogen is not a component.
