HS Code for Ammonium sulfate fertilizer

Ammonium sulfate, when specifically prepared and presented as a fertilizer, is classified under HS Chapter 31, which is dedicated to fertilizers. Within this chapter, heading 3102 covers "Mineral or chemical fertilizers, nitrogenous". Subheading 3102.21 is explicitly designated for "Ammonium sulphate". This classification is precise because the product is chemically ammonium sulfate and its intended use is as a fertilizer, aligning perfectly with both the chemical identity and the functional purpose described in the HS nomenclature. This distinction based on use is critical for correct classification.

Products Included

• Granular ammonium sulfate fertilizer
• Crystalline ammonium sulfate fertilizer
• Blended fertilizers where ammonium sulfate is the primary nitrogen component
• Ammonium sulfate solutions for agricultural application

Common Misclassification

A common misclassification involves distinguishing between ammonium sulfate as an industrial chemical and as a fertilizer. If ammonium sulfate is not presented or intended for use as a fertilizer, it would be classified under HS code 2833.29 as an inorganic chemical, specifically "Other sulphates". The distinction hinges entirely on the product's primary intended use and its presentation (e.g., packaging, marketing). Another potential confusion could be with other nitrogenous fertilizers, such as urea (3102.10) or ammonium nitrate (3102.30). However, the specific chemical identity of ammonium sulfate directs it unambiguously to 3102.21 when it functions as a fertilizer.

FAQ

What is the HS code for Ammonium sulfate fertilizer?

The HS code for Ammonium sulfate fertilizer is 310221.

How does the HS code differentiate between ammonium sulfate as a chemical and as a fertilizer?

The HS code differentiates based on the product's primary intended use and presentation. If ammonium sulfate is prepared, marketed, and packaged for agricultural purposes as a nutrient source, it falls under Chapter 31 (Fertilizers). If it is an industrial chemical for other applications (e.g., water treatment, food additive), it is classified under Chapter 28 (Inorganic Chemicals).
