Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If mixed with other fertilizer substances
Blends containing potassium nitrate for direct agricultural use shift to Chapter 31 fertilizers, excluding pure compounds.
If prepared for explosive manufacture
Mixtures or preparations specifically for detonators or explosives fall under Chapter 36, not pure nitrates.
If containing silver or gold
Nitrates of precious metals are classified separately in heading 2843, per Chapter 28 notes excluding them from 2834.
