About Duty Rates: Rates are divided into Column 1 and Column 2. Column 1 is subdivided into General (normal trade relations rates for all countries not eligible for special programs) and Special (preferential rates for countries with free trade agreements or preference programs). Column 2 rates apply to products from Cuba, North Korea, Belarus, and Russia. When no special rate exists for a classification, General rates apply.

Overview

This classification, HTS Code 3102.29.00.00, covers "Other" nitrogenous fertilizers that fall under the broader category of ammonium sulfate, double salts, and mixtures of ammonium sulfate and ammonium nitrate, but do not fit into the specifically defined subheading. Essentially, it serves as a residual category for these types of nitrogenous fertilizers that do not qualify for more precise subheadings within this group.

The key distinction from its sibling category, 3102.21.00.00 (Ammonium sulfate), is that this subheading is not exclusively for pure ammonium sulfate. Instead, it encompasses products that are either mixtures containing ammonium sulfate, or double salts which are compounds formed from two different salts where ammonium sulfate is a component, but the overall composition is not solely ammonium sulfate. The classification hinges on the presence of ammonium sulfate as a primary constituent, alongside other salts or components.

As this is a leaf node, there are no further subcategories to introduce. Classification into this subheading requires careful examination of the product's composition. If a product is a nitrogenous fertilizer primarily composed of ammonium sulfate, but contains other compounds making it a mixture or a double salt not specifically defined elsewhere, it will be classified here. The determination will depend on the chemical analysis and the precise formulation of the fertilizer.
