## Common ground
All options describe soleplates for steam irons, the flat base that contacts fabric during ironing.
## Options at a glance
**3926.90 – Plastic soleplate**
- **Defining trait:** Made from plastic, typically lightweight and resistant to corrosion.
- **Typical examples:** Non-stick coated plastic plates in budget or travel irons.
- **Best fit when:** Lightweight design, low cost, or non-metallic surface is preferred.
**7615.10 – Aluminium soleplate**
- ** **Defining trait:** Made from aluminium, offering better heat conductivity and durability.
- **Typical examples:** High-performance irons with even heat distribution and long lifespan.
- **Best fit when:** Fast heating, consistent temperature control, or professional use is needed.
## Key differences
| Feature | 3926.90 (Plastic) | 7615.10 (Aluminium) |
|------------------|--------------------------|----------------------------|
| Material | Plastic | Aluminium |
| Heat conductivity| Low | High |
| Durability | Lower (prone to scratches)| Higher (resists wear) |
| Weight | Lighter | Heavier |
## How to choose
- Does the soleplate feel light and non-metallic? → 3926.90
- Is it made of a shiny, heavy metal that heats quickly? → 7615.10
## Overlaps & pitfalls
A plastic soleplate may have an aluminium coating or insert, but if the base is primarily plastic, use 3926.90. Aluminium soleplates may be coated (e.g., non-stick), but the core material determines classification. The main function—heat transfer and durability—should guide choice: prioritize conductivity for performance, lightweight for portability
