HS Code for Phosphatic fertilizer

Phosphatic fertilizers that do not fall under the more specific categories of superphosphates are classified under HS code 3103.90. Chapter 31 of the Harmonized System is dedicated to fertilizers. Heading 3103 specifically covers mineral or chemical fertilizers that are phosphatic in nature. While superphosphates are categorized under 3103.11 and 3103.19, the "other" category (3103.90) captures various phosphatic mineral products used to enrich soil. This includes basic slag and other phosphatic materials not specifically named elsewhere in the heading. The classification depends on the chemical composition and the intended use as a fertilizer, provided the product is not a mixture containing nitrogen or potassium, which would shift it to heading 3105. To qualify for Chapter 31, the product must be intended for use as a fertilizer and must contain phosphorus as the primary nutrient. This code is essential for distinguishing between common superphosphates and more specialized or less common phosphatic mineral treatments used in agriculture.

Products Included

• Basic slag (Thomas slag)
• Calcined natural phosphates
• Fused phosphates
• Other mineral or chemical phosphatic fertilizers not elsewhere specified
• Ground or unground phosphatic rock treated for fertilizer use

Common Misclassification

The most common misclassification is using 3103.11 or 3103.19, which are reserved specifically for superphosphates. Another error is classifying these under 3105.20 or 3105.30 if the product contains even trace amounts of nitrogen or potassium; heading 3105 is for multi-nutrient fertilizers. Additionally, raw phosphate rock that has not been chemically treated is classified in 2510 rather than 3103.

FAQ

What is the HS code for Phosphatic fertilizer?

For phosphatic fertilizers other than superphosphates, the HS code is 3103.90.

What is the difference between 3103 and 3105?

Heading 3103 is for fertilizers containing only phosphorus as a nutrient, while 3105 is for fertilizers containing two or three fertilizing elements (nitrogen, phosphorus, and potassium).
