## Common ground
All options are breast pumps that extract milk, differing only in their operating mechanism.
## Options at a glance
**8413.20 – Hand operated**
- **Defining trait:** Operated manually without electricity or vacuum systems.
- **Typical examples:** Manual syringe-style pumps, hand-squeeze pumps.
- **Best fit when:** Portability, no power source needed, low cost.
**8413.81 – Electronic (non-vacuum)**
- **Defining trait:** Powered by electricity or batteries; uses non-vacuum mechanisms (e.g., piston, peristaltic).
- **Typical examples:** Battery-powered electric pumps with motor-driven action.
- **Best fit when:** Convenience, consistent pumping speed, longer use sessions.
**8414.10 – Vacuum pump**
- **Defining trait:** Uses a vacuum (suction) system to extract milk, typically via a motorized pump.
- **Typical examples:** Double electric breast pumps with suction control.
- **Best fit when:** Strong, consistent suction; medical or frequent use.
## Key differences
| Feature | 8413.20 (Hand) | 8413.81 (Electronic) | 8414.10 (Vacuum) |
|------------------|----------------|------------------------|------------------|
| Power source | Manual | Battery/electric | Electric motor |
| Suction method | No vacuum | Non-vacuum mechanism | Vacuum-based |
| Use intensity | Low | Medium to high | High |
## How to choose
- Does it require no power or batteries? → 8413.20
- Is it electric but does not use suction/vacuum? → 8413.81
- Does it use a motorized vacuum system for suction? → 8414.10
## Overlaps & pitfalls
- Some electronic pumps (8413.81) may include vacuum-like action, but if they rely on suction via a pump mechanism, they belong in 8414.10.
- "Vacuum pump" (8414.10) is the only one with true suction-based operation; others use mechanical or motor-driven non-vacuum methods.
- If unclear, prioritize the **main operating principle**: manual → hand; electric + no vacuum → 8413.81; electric + suction → 8414.10
