Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing only urea as nitrogen source without phosphorus
Pure urea fertilizers fall under heading 3102, but adding phosphorus creates a two-nutrient mix requiring 3105 classification
If packaged in retail bags over 10kg gross weight
Heading 3105 applies only to packages ≤10kg; larger retail packages shift to diammonium hydrogenorthophosphate classification
If containing additional micronutrients beyond N-P
Products with more than two primary fertilizing elements fall under the 'other fertilizers' subheading
