Last updated: July 2026 dataUrea, ammonium nitrate, ammonium sulfate, and urea-ammonium nitrate (UAN) solutions are the principal nitrogenous fertilizers traded under this NAICS line, classified in HTS Chapter 31 by nitrogen compound type and concentration. Antidumping and countervailing duty orders have targeted specific nitrogen fertilizer products — including UAN solutions — from multiple origins, and importers must verify current order scope before contracting. Because ammonia synthesis is energy-intensive, global natural gas price swings create significant landed-cost variability that trade professionals must factor into procurement planning.

Yes. The US has maintained antidumping duty orders on UAN solutions from certain origins. The scope of these orders is product- and origin-specific, and importers should consult the Department of Commerce's Enforcement and Compliance database and obtain a scope ruling if their product's classification is uncertain.
Bulk liquid nitrogen fertilizers such as UAN require standard CBP entry documentation, a commercial invoice with nutrient concentration details, and a bill of lading. If the product contains ammonium nitrate above certain thresholds, additional DHS/EPA hazardous materials reporting may apply. Importers should also confirm whether the specific origin and product are subject to any active ADD/CVD orders before shipment.
