HS Code for SOP fertilizer
SOP (Sulphate of Potash) fertilizer, chemically known as potassium sulphate, is classified under HS code 3104.30. This classification is governed by the notes in Chapter 31, which covers fertilizers. Heading 3104 is specifically designated for mineral or chemical fertilizers, potassic. Within this heading, 3104.30 is the specific subheading for potassium sulphate. To be classified here, the product must be of a kind used as a fertilizer or be a separate chemically defined compound of potassium sulphate. SOP is highly valued in agriculture for providing both potassium and sulphur while maintaining a low chloride content, making it ideal for chloride-sensitive crops. The classification remains consistent whether the product is in crystalline, powder, or granular form, provided it is not put up in tablets or similar forms or in packages of a gross weight not exceeding 10 kg, which would move it to heading 3105.
Products Included
- Agricultural grade potassium sulphate
- Water-soluble SOP for fertigation
- Granular SOP fertilizer
- Crystalline potassium sulphate (K2SO4)
- Industrial grade potassium sulphate used as fertilizer
Common Misclassification
SOP is often confused with MOP (Muriate of Potash), which is potassium chloride and is classified under HS code 3104.20. While both are potassic fertilizers, they are distinct chemical compounds with different subheadings. Another common misclassification occurs with HS code 3105.20, which covers NPK fertilizers. If SOP is blended with nitrogen or phosphorus, it must be moved to 3105. Additionally, if the SOP is packaged for retail sale in bags weighing 10 kg or less, it must be classified under HS code 3105.10, regardless of its chemical purity, as per the rules of Chapter 31.
FAQ
What is the HS code for SOP fertilizer?
The HS code for SOP (potassium sulphate) fertilizer is 3104.30.
Is potassium sulphate classified differently if it is food grade?
If potassium sulphate is not intended for use as a fertilizer and is a pure chemical, it might still fall under 3104.30, but some jurisdictions may look at 2833.29; however, for most trade, 3104.30 is the standard.
