What is NOT Classified Here?
To ensure correct classification, note the following exclusions:
- Inorganic hydrazine compounds and their salts are classified under different HTS codes.
- Simple hydrazine or hydroxylamine substances without organic derivatives fall outside this heading.
- Other organic nitrogen compounds not derived from hydrazine or hydroxylamine are classified elsewhere in Chapter 29.
