2809.20.00.20 - Other 🖩

This HTS classification, 2809.20.00.20, specifically covers "Other" phosphoric acid when it is intended for fertilizer applications. This designation implies that any fertilizer-grade phosphoric acid not explicitly defined by its P2O5 content will fall under this residual category. The primary characteristic is its composition as phosphoric acid (H₃PO₄) or polyphosphoric acids, chemically defined or not, which are utilized in the agricultural sector for nutrient enhancement of soil and plant growth.

This category is distinguished from its sibling, 2809.20.00.10, by its lack of a specified minimum percentage of available diphosphorus pentaoxide (P2O5) equivalents. The sibling category is for fertilizer-grade phosphoric acid containing less than 65 percent P2O5 equivalents. Therefore, 2809.20.00.20 is a catch-all for fertilizer-grade phosphoric acid where this specific P2O5 threshold is not a determining factor for classification.

As this is a leaf node within the HTS structure, there are no further subcategories for this specific classification. The scope is finalized at this point, encompassing all remaining fertilizer-grade phosphoric acids that do not fit into more specific subdivisions. When classifying under this code, importers and exporters should ensure that the product is indeed phosphoric acid or polyphosphoric acids intended for fertilizer use and does not meet the criteria of any preceding, more specific fertilizer-grade phosphoric acid subcategories.
