- **Best fit when:** The dispenser has visible wood grain, is handcrafted, or uses wood veneers.
**7324.90 – Iron or steel**
- **Defining trait:** Made from metal, typically durable and heavy-duty; often used in high-traffic areas.
- **Typical examples:** Industrial-grade dispensers, wall-mounted steel units, commercial bathroom fixtures.
- **Best fit when:** The dispenser is made of iron, steel, or similar metallic material.
**8479.89 – Mechanical paper roll towel dispensers, hands-free with sensors**
- **Defining trait:** Uses mechanical or sensor-based operation (e.g., motion-sensor activation); not just a passive holder.

## Key differences
| Feature | 3925.90 (Plastic) | 4420.90 (Wood) | 7324.90 (Metal) | 8479.89 (Sensor) |
|-----------------------|-------------------|----------------|------------------|------------------|
| Material | Plastic | Wood | Iron/Steel | Varies |
| Operation | Manual | Manual | Manual | Automatic |

## How to choose
1. Is the dispenser made of plastic? → 3925.90
2. Is it made of wood or wood-like material (e.g., veneer)? → 4420.90
3. Is it made of iron or steel? → 7324.90
4. Does it use a sensor to dispense towels automatically? → 8479.89
## Overlaps & pitfalls
- A metal dispenser with a sensor could fit both **7324.90** and **8479.89**. In such cases, prioritize the **operation mode (sensor)** if automation is the key feature.
- "Plastic" or "wood" dispensers may still have sensors—this would make them fall under **8479.89**, which takes precedence due to its functional specificity.
- If unsure, ask: *Is the main function automatic operation?* → Choose 8479.89. Otherwise, use material to decide
