## Common ground
All options are sound-producing devices used for signaling, alerting, or musical purposes.
## Options at a glance
**8306.10 – Non-electric**
- **Defining trait:** Produces sound through manual striking or mechanical action without electricity.
- **Typical examples:** Handbell, brass gong, temple block, wind chime.
- **Best fit when:** The device is struck by hand, mallet, or natural motion (e.g., wind), with no electrical components.
**8531.80 – Electric or battery operated**
- **Defining trait:** Uses electricity or battery power to generate sound, often via electronic circuits or electromagnets.
- **Typical examples:** Electronic bell, battery-powered door chime, electric gong with built-in timer.
- **Best fit when:** The device requires power to produce sound, even if it mimics traditional tones.
## Key differences
| Feature | 8306.10 (Non-electric) | 8531.80 (Electric/battery) |
|---------------------|------------------------|----------------------------|
| Power source | None (manual/mechanical) | Electricity or battery |
| Sound generation | Physical impact | Electronic/electromagnetic |
| Typical use case | Music, traditional signaling | Alarms, automated systems |
## How to choose
- Does it require electricity or a battery to make sound? → 8531.80
- Is it struck by hand, mallet, or wind with no power source? → 8306.10
## Overlaps & pitfalls
A device like an electric gong that can also be manually struck may fit both categories. In such cases, the **main function** determines classification: if it's primarily used via electricity (e.g., automated door chime), use 8531.80; if used as a musical instrument with manual striking, use 8306.10. No priority rule is implied—choose based on primary operation
