3102.10.00 - Urea, whether or not in aqueous solution

This HTS category, 3102.10.00, specifically covers urea, a primary nitrogenous fertilizer essential for plant growth. It encompasses urea in its pure solid form, as well as solutions where urea is dissolved in water. Urea is highly valued for its high nitrogen content and ease of application in agricultural settings.

While other categories within mineral fertilizers, nitrogenous (3102) address different nitrogen-containing compounds, this sub-heading is exclusively dedicated to urea. For instance, siblings like ammonium sulfate (3102.20) and ammonium nitrate (3102.30) are distinct chemical compounds with their own unique properties and classification rules, even though they serve similar fertilizing purposes. This differentiation is crucial for accurate customs declarations and tariff application.

This category has further subdivisions to refine the classification of urea. Sub-category 3102.10.00.10 specifically identifies solid urea, distinguishing it from urea in aqueous solution. The subsequent "Other" subcategory exists to capture any remaining forms of urea that do not fall under the solid classification, ensuring comprehensive coverage within the broader urea designation.
