HS chapter 31: Fertilisers
Section VI — Products of the chemical or allied industries
Goods classified under this chapter include various fertilizers, such as nitrogenous fertilizers like urea or phosphatic fertilizers like superphosphate. For instance, if you're importing a shipment of ammonium nitrate, you would refer to this chapter for the appropriate classification.
To determine the correct HS-4 code, start by identifying the primary ingredient of your fertilizer. If it’s animal or vegetable-based, you’ll likely look at 3101. For mineral or chemical fertilizers, check if they are nitrogenous (3102), phosphatic (3103), or potassic (3104). Each of these categories has specific criteria that can help narrow down your choice.
Next, consider the composition of your fertilizer. If it contains multiple elements, such as nitrogen, phosphorus, and potassium, you’ll want to explore 3105. This code also applies to smaller packages weighing 10 kg or less. Pay attention to the product form and intended use to avoid misclassification.
Review the notes associated with each HS-4 code for additional details or exceptions that might apply to your specific product. If you're unsure, consulting with a customs broker can provide clarity and ensure compliance with national regulations.
