HS Code for Potassium chloride fertilizer

Potassium chloride is classified under HS code 3104.20 because it is a mineral or chemical fertilizer of the potassic variety. Chapter 31 of the Harmonized System covers fertilizers, and heading 3104 specifically addresses potassic fertilizers. For a product to be classified here, it must be intended for use as a fertilizer or be in a form commonly used for such purposes. Potassium chloride, often referred to as Muriate of Potash (MOP), is the most widely used potassium fertilizer in agriculture globally. The classification depends on the purity and the intended application; however, standard agricultural grade potassium chloride is strictly governed by this code. It provides essential nutrients to crops, helping with water retention, enzyme activation, and disease resistance. The Harmonized System ensures that such vital agricultural inputs are tracked consistently across international borders to facilitate trade and monitor agricultural trends. This code is specifically for the chloride salt of potassium when used in a fertilizing capacity, distinguishing it from industrial-grade chemicals. The physical form, whether granular, crystalline, or powder, does not change the classification as long as the primary use remains soil enrichment.

Products Included

• Agricultural grade potassium chloride
• Muriate of Potash (MOP)
• Granular potassium chloride for soil application
• Soluble potassium chloride for fertigation systems
• Standard grade potassic fertilizer salts

Common Misclassification

A frequent point of confusion is between HS code 3104.20 and HS code 2827.39. While 3104.20 is for fertilizer-grade potassium chloride, 2827.39 covers potassium chloride as a pure chemical compound used in industrial, pharmaceutical, or laboratory settings. If the product is of high purity (e.g., USP or analytical grade) and not intended for soil enrichment, it should be classified under Chapter 28. Additionally, it is sometimes confused with 3104.30, which is specifically for potassium sulfate.
