3104.20.00.50 - Containing more than 62 percent by weight of potassium oxide (K2O)

This HTS classification covers potassium chloride-based fertilizers that contain a high concentration of potassium oxide (K2O), specifically exceeding 62 percent by weight. These products are primarily used as mineral fertilizers to supply essential potassium nutrients to crops, promoting healthy growth, disease resistance, and improved yield. The classification specifically targets granular or powdered forms of potassium chloride that meet this elevated K2O threshold.

The key differentiator for this category is the percentage of potassium oxide by weight. It is distinct from its sibling category, HTS 3104.20.00.10, which encompasses potassium chloride fertilizers containing 62 percent or less K2O. This precise numerical threshold is the sole determining factor for distinguishing between these two closely related classifications, ensuring accurate tariff application based on the specific chemical composition of the fertilizer.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, classification into this specific code is determined solely by meeting the criteria of being potassium chloride and containing more than 62 percent by weight of potassium oxide (K2O). Examples of products falling under this classification would be high-analysis potassium chloride fertilizers marketed for their concentrated potassium content.
