What is NOT Classified Here?
To avoid misclassification, note these exclusions:
- Other organic chemicals without carboxyimide or imine functional groups are classified elsewhere in Chapter 29.
- Inorganic chemicals and salts not containing the specified functional groups.
- Prepared pharmaceutical formulations are typically classified under Chapter 30.
Notes
- Usage and Applications: Many of the compounds classified here serve as intermediates or additives in pharmaceuticals, polymers, flame retardants, and agriculture chemicals.
- Regulatory Considerations: Some substances may be controlled due to their pharmaceutical nature or chemical reactivity.
- Duty Rates: Duty rates for these chemical compounds vary depending on the exact substance and country of origin; importers should consult the latest USHTS schedule.
