## Overlaps & pitfalls
- A sugar-free gum (2106.90) might also contain chlorophyll (3004.90), but the **main function** determines the code. If health claim is primary, use 3004.90; if flavoring only, use 2106.90.
- A breath spray (3306.90) might be sugar-free—still fits 3306.90 unless it claims therapeutic use.
- No option clearly prioritizes "natural ingredients" or "essential oils"—those are secondary traits.
- **Choose based on the product’s MAIN function**: flavoring, hygiene, therapy, or physical tool integration
