## Common ground
Both options describe non-electric, manually operated tools used for processing fruit by removing stones.
## Options at a glance
**8205.51 – Hand tools of base metal**
- **Defining trait:** Designed primarily as handheld tools with a simple mechanical function, typically used directly by hand without being mounted or powered.
- **Typical examples:** Fruit corers, manual pitters, hand-held seed removers.
- **Best fit when:** The device is small, lightweight, and operated entirely by hand with no moving parts beyond the tool itself.
**8210.00 – Mechanical appliances under 10 kg**
- **Defining trait:** A more complex mechanical device that may include moving parts, a frame, or a mechanism for consistent operation, even if manually powered.
- **Typical examples:** Manual fruit stoners with rotating cranks, lever systems, or adjustable chucks.
- **Best fit when:** The tool has a structured design with multiple components working together (e.g., a crank and press mechanism), even without electricity.
## Key differences
| Feature | 8205.51 – Hand tools of base metal | 8210.00 – Mechanical appliances under 10 kg |
|-----------------------|------------------------------------|---------------------------------------------|
| Complexity | Simple, single-function tool | Multi-part, mechanized design |
| Operation | Direct hand use | Lever, crank, or press mechanism |
| Weight & Structure | Lightweight, no frame | May have a base or housing |
## How to choose
- Is it just a simple handheld tool (like a pusher or corer)? → 8205.51
- Does it have moving parts like a crank, lever, or adjustable clamp? → 8210.00
## Overlaps & pitfalls
A fruit stoner with a handle and a single metal point may fit both. If the device has a mechanism (e.g., a rotating screw or press), prioritize **8210.00**. The key is whether it functions as a *tool* or a *mechanical appliance*. When in doubt, use the **main function**: if it’s primarily a hand-held implement, choose 8205.51; if it uses mechanical advantage via a system, choose 8210.00
