Overview

This HTS classification, 3104.90.01.00, is designated for "Other" mineral or chemical fertilizers, potassic, that do not fall under the more specific categories of potassium chloride (3104.20.00) or potassium sulfate (3104.30.00.00). This category serves as a residual for potassic fertilizers, encompassing a variety of compounds or mixtures where potassium is a principal nutrient element but the product is not solely potassium chloride or potassium sulfate.

The distinction from its sibling categories is crucial. While 3104.20.00 specifically covers potassium chloride (often referred to as Muriate of Potash or MOP) and 3104.30.00.00 covers potassium sulfate (Sulfate of Potash or SOP), this "Other" category captures potassic fertilizers that might be natural potassium magnesium sulfate (potash-magnesia), potassium nitrate, or complex fertilizers containing potassium in combination with other nutrients, provided they are not predominantly classified as the aforementioned specific salts.

As this is a leaf node, there are no further subcategories within 3104.90.01.00. Classification into this category hinges on identifying a potassic fertilizer that does not meet the exact composition or chemical definition of potassium chloride or potassium sulfate. Importers and exporters should ensure that the product's chemical composition and intended use as a fertilizer are clearly documented to justify its classification under this residual heading.
