3104.20.00.10 - Containing not more than 62 percent by weight of potassium oxide (K2O)

This HTS category, 3104.20.00.10, specifically classifies potassium chloride-based fertilizers that contain a maximum of 62 percent by weight of potassium oxide (K2O). These products are essential agricultural inputs designed to supply potassium, a vital nutrient for plant growth and development, contributing to improved crop yield and quality.

This classification is distinct from its sibling category, 3104.20.00.50, which covers potassium chloride fertilizers with a higher concentration, exceeding 62 percent by weight of potassium oxide (K2O). The key differentiating factor for this specific subcategory is its comparatively lower potassium oxide content, meaning it is a less concentrated form of potassium chloride fertilizer.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, classification under 3104.20.00.10 relies solely on the accurate determination of the potassium oxide (K2O) content. Importers and exporters should ensure their product's chemical analysis confirms it meets the "not more than 62 percent by weight of potassium oxide" requirement to ensure proper declaration.
