Import Tips
• Provide detailed blending ratios in commercial invoice to prove mixture status; imbalances may lead to classification as 3102.30 ammonium nitrate
• Label as 'non-pressurized UAN solution' to distinguish from explosive-grade materials requiring hazmat declarations
• Pre-register as agricultural input with USDA/AP HIS if importing to US; test for biuret content to ensure quality compliance
