How to choose the right subheading

Decide whether the product is a nitrite (2834.10) or a nitrate (2834.21 or 2834.29).
For nitrites, use 2834.10.10.00 for sodium nitrite and 2834.10.50.00 for other nitrites.
For nitrates, use 2834.21.00.00 for potassium nitrate.
For other nitrates, identify the metal cation: bismuth 2834.29.05.00, calcium 2834.29.10.00, strontium 2834.29.20.00, or other 2834.29.51.00.
