Overview

This HTS category, 3105.20.00.00, specifically encompasses mineral or chemical fertilizers that uniquely contain all three primary fertilizing elements: nitrogen (N), phosphorus (P), and potassium (K). These fertilizers are designed to provide a comprehensive nutrient profile for plant growth, supplying essential macronutrients in a single product. Examples include compound fertilizers formulated with urea, superphosphate, and potassium chloride, or complex fertilizers where these elements are chemically bonded.

It is crucial to distinguish this category from its siblings. Category 3105.10.00.00 covers goods from Chapter 31 presented in specific small-quantity retail formats like tablets or packages not exceeding 10 kg, regardless of their nutrient composition. Other sibling categories, such as 3105.30.00.00 (Diammonium hydrogenorthophosphate) and 3105.40.00 (Ammonium dihydrogenorthophosphate), are for specific diammonium phosphate products. Additionally, categories for fertilizers containing only two of the primary elements, like phosphorus and potassium (3105.60.00.00), are separate. Therefore, 3105.20.00.00 is reserved exclusively for products explicitly providing nitrogen, phosphorus, and potassium together.

As this is a leaf node in the HTS, there are no further subcategories branching from 3105.20.00.00. Classification within this code relies solely on the presence of all three fertilizing elements. Importers and exporters must ensure that the product's guaranteed analysis or composition clearly indicates the inclusion of nitrogen, phosphorus, and potassium to correctly classify under this heading.
