3105.40.00.50 - Other

This HTS category, 3105.40.00.50, encompasses "Other" fertilizing compounds that fall under the broader classification of mineral or chemical fertilizers. Specifically, it covers substances containing two or three of the primary fertilizing elements: nitrogen, phosphorus, and potassium. This category is designed to capture fertilizer products that are not specifically enumerated in more detailed subheadings within the 3105 chapter.

This classification is distinct from its sibling category, 3105.40.00.10, which specifically covers Ammonium dihydrogenorthophosphate (Monoammonium phosphate) on its own. Category 3105.40.00.50 is intended for situations where the fertilizer is either a combination of Monoammonium phosphate and Diammonium phosphate, or other complex fertilizer compounds that meet the general criteria of containing nitrogen, phosphorus, and potassium but do not fit into more precise classifications.

As this is a leaf node, there are no further subcategories for this specific code. Therefore, the classification hinges on the precise chemical composition and formulation of the fertilizer. Importers and exporters should carefully examine the product's declared components and compare them against the descriptions of more specific fertilizer codes to ensure accurate classification under this "Other" residual category when applicable.
