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

HTS Code 3102.90.01.00 encompasses all nitrogenous mineral or chemical fertilizers not specifically classified under preceding subheadings within the 3102 series. This broad category is designed to capture those nitrogenous fertilizer products that do not fit neatly into the more specific groupings of urea, ammonium sulfate, ammonium nitrate, or sodium nitrate. It serves as a residual classification for nitrogenous fertilizers that are otherwise identifiable as such but lack a more precise classification elsewhere.

Distinguishing this category from its siblings is crucial for accurate classification. Unlike 3102.10.00 which exclusively covers urea, or 3102.30.00.00 and 3102.40.00.00 which deal with ammonium nitrate and its mixtures, 3102.90.01.00 is for those nitrogenous fertilizers that are neither urea nor primarily ammonium nitrate. Similarly, it excludes the specific classification of sodium nitrate (3102.50.00.00). This subheading is for nitrogenous fertilizers that do not fall into these more defined categories, including various nitrogen compounds or mixtures whose primary function is fertilization.

As a leaf node within the HTS, 3102.90.01.00 does not have further subcategories. Therefore, classification within this heading relies heavily on the exclusion of goods from the preceding, more specific nitrogenous fertilizer subheadings. When a nitrogenous fertilizer cannot be classified under urea, ammonium sulfate, ammonium nitrate, or sodium nitrate, it will be examined to determine if it qualifies for this "Other" category. The key criterion remains that the substance must be a nitrogenous mineral or chemical fertilizer and not specifically described elsewhere in the 3102 chapter. Examples could include calcium ammonium nitrate (unless specifically covered by 3102.40.00.00 if it's a mixture with calcium carbonate or other inert substances), or certain organo-mineral nitrogenous compounds that are primarily intended for use as fertilizers.
