HS Code for Potassic fertilizer
Potassic fertilizers are classified under HS code 3104.90 when they do not fall into the more specific subheadings of Heading 3104. Chapter 31 of the Harmonized System is dedicated to fertilizers, and Heading 3104 specifically covers mineral or chemical potassic fertilizers. Subheading 3104.90 is a residual category for potassic fertilizers other than potassium chloride (3104.20) or potassium sulfate (3104.30). This classification includes natural potassium salts, such as carnallite or sylvite, and mixtures of potassic fertilizers. According to Note 4 to Chapter 31, Heading 3104 applies only to specific products like unpurified potassium salts and products mixed together. The classification is essential for distinguishing between pure chemicals (Chapter 28) and products intended for soil enrichment. Even if these products are used for industrial purposes, they remain in Chapter 31 if they meet the descriptions provided in the Chapter Notes.
Products Included
- Crude natural potassium salts
- Carnallite and kainite
- Sylvite (potassium chloride in natural form)
- Magnesium potassium sulfate mixtures
- Other mineral potassic fertilizers not elsewhere specified
Common Misclassification
Potassic fertilizers are frequently confused with multi-nutrient fertilizers under Heading 3105. If the fertilizer contains nitrogen or phosphorus in addition to potassium, it must be classified under 3105. Another common error is classifying pure, chemically defined potassium compounds under 3104; if they are not specifically listed in the Chapter 31 notes, they may belong in Chapter 28. For example, pure potassium nitrate is classified under 2834.21, even if used as a fertilizer.
