Last updated: August 2026 dataUrea ammonium nitrate solution (UAN) is a liquid nitrogen fertilizer — typically 28%, 30%, or 32% nitrogen — that is one of the most widely applied nitrogen sources in US row-crop agriculture, used for pre-plant, side-dress, and fertigation applications. Classified under 3102800000, US imports arrive predominantly from Russia and Trinidad and Tobago, with Canada and the Netherlands also supplying the market. Russian-origin UAN has been subject to antidumping and countervailing duty orders, making origin verification and AD/CVD deposit calculations a routine compliance step for importers. The liquid form requires specialized tanker vessels and terminal infrastructure, concentrating import activity at Gulf Coast and inland river terminals.

Yes, antidumping and countervailing duty orders have been imposed on UAN solution from Russia, and orders have also covered other origins at various times. Importers must check the current scope of active orders with CBP or the International Trade Commission before entry, as AD/CVD cash deposits are required at time of importation and can significantly affect landed cost.
UAN solution must be transported in corrosion-resistant liquid tankers or barges and stored in dedicated liquid fertilizer tanks at import terminals. This limits viable entry points to ports with liquid fertilizer terminal capacity — primarily Gulf Coast and Mississippi River facilities — and requires coordination between vessel operators, terminal operators, and inland transport providers well in advance of the application season.
