## Key differences
| Material | Weight | Durability | Corrosion Resistance | Typical Use Case |
|----------------|----------|------------|------------------------|----------------------------|
| Plastic | Light | Low–Medium | High | Home, temporary use |
| Wood | Medium | Medium | Low (needs treatment) | DIY, indoor workshops |
| Stone | Very Heavy | High | High | Permanent architecture |
| Concrete/Art. Stone | Heavy | Very High | High | Construction sites |
| Iron/Steel | Heavy | Very High | Low (rusts if untreated)| Industrial, heavy-duty |
| Aluminium | Light | High | High | Portable, outdoor use |
## How to choose
- Is the product made of plastic? → 3926.90
- Is it made of natural wood? → 4421.9X
- Is it heavy and built from stone or concrete? → 6802.2X,6802.9X or 6810.99
- Is it made of metal (iron/steel)? → 7326.90
- Is it made of aluminum alloy? → 7616.99
## Overlaps & pitfalls
A product may combine materials (e.g., aluminum frame with plastic steps), but the **main structural material** determines the correct code. If unclear, prioritize the primary load-bearing component. No option is vague—each clearly defines a distinct material group
