3105
In plain English
This category covers fertilizers made from minerals or chemicals that contain two or three of the key elements: nitrogen, phosphorus, and potassium. It also includes other types of fertilizers and any goods from this chapter that are packaged in tablets or containers weighing ten kilograms or less. The specific subcategories separate these items based on their chemical composition, such as those containing all three main elements, specific phosphate compounds like diammonium or monoammonium phosphate, or mixtures of nitrogen and phosphorus without nitrates. Additional divisions distinguish products by the presence of nitrates, combinations of phosphorus and potassium, or other fertilizers not listed elsewhere in this group.
