Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If diluted for agricultural fertilizer use
Phosphoric acid blended into superphosphate fertilizers shifts to Chapter 31 for mineral/chemical fertilizers.
If converted to sodium or potassium phosphates
Metal salts of phosphoric acid are classified under heading 2835, not the acid itself.
If mixed with organic stabilizers for retail
Preparations containing phosphoric acid with additives become chemical preparations in 3824.
