How to choose the right subheading
- Decide whether the product is nitric acid alone or a mixture of nitric acid with sulfuric acid.
- Use 2808.00.00.10 for nitric acid, including water solutions and fuming grades.
- Use 2808.00.00.20 for sulfonitric acids, meaning nitric acid and sulfuric acid mixtures.
- Do not use 2808 for nitrate salts; those are classified in heading 2834.
- Purity or intended use does not create another line in the provided heading data.
