3102.10.00.50 - Other

This classification covers urea, whether or not in aqueous solution, intended for use as a fertilizer, that does not meet the specific criteria for other subcategories. It encompasses various forms of urea, including granular, prilled, and crystalline, that are not otherwise categorized. The primary purpose of goods classified here is nutrient provision for plant growth in agricultural and horticultural applications.

It is important to distinguish this category from its sibling, HTS 3102.10.00.30, which specifically covers Diesel Exhaust Fluid (DEF) meeting ISO 22241 standards. While DEF is urea-based, its application as an emissions control additive, rather than a direct fertilizer, places it in a distinct classification. Therefore, this "Other" category applies to urea solely intended for its fertilizing properties.

As this is a leaf node, there are no further subdivisions under this specific HTS code. Classification at this level is determined by the product being urea, in any form, and its intended use as a fertilizer, provided it is not classified under the more specific DEF subcategory.
