Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If when packaged for retail sale in consumer-ready containers
Retail-packed diammonium phosphate fertilizers shift to Chapter 31 heading 3105 for consumer products.
If mixed with urea to form UAN solution exceeding simple aqueous ammonium nitrate
Mixtures of ammonium nitrate with urea in solution fall under specific subheading for those combinations.
If when imported as high-purity chemical grade rather than fertilizer application
Chemically pure ammonium nitrate for non-fertilizer industrial synthesis moves to Chapter 29 organic chemicals.
