3104.30.00.00 - Potassium sulfate

This HTS category, 3104.30.00.00, specifically covers potassium sulfate, a vital chemical compound utilized primarily as a fertilizer. Potassium sulfate is characterized by its chemical composition and is valued for providing both potassium and sulfur, essential nutrients for plant growth. Its distinct chemical properties and application as a source of these specific nutrients differentiate it within the broader scope of potassic fertilizers.

Within the context of Chapter 31, which deals with fertilizers, this classification stands apart from its siblings. It is distinct from 3104.20.00, which enumerates potassium chloride (often referred to as muriate of potash), a different chemical compound with a varying ratio of potassium and a lack of sulfur content. It also differs from the residual category 3104.90.01.00, which encompasses all other potassic fertilizers not specifically defined elsewhere in this heading.

As this is a leaf node in the HTS classification, there are no further subcategories for potassium sulfate. Therefore, the classification relies on the definitive identification of the material as potassium sulfate, ensuring accurate import and export declarations for this specific fertilizer product. Classification decisions for this code would typically hinge on laboratory analysis confirming the chemical composition and purity of the substance.
