## How to choose
- Is the cart made of metal (e.g., steel, aluminum)? → 9403.10
- Is it primarily solid wood? → 9403.30
- Is it molded plastic or rigid plastic? → 9403.70
- Is it made from bamboo? → 9403.82
- Is it woven from rattan? → 9403.83
- Does it use cane, osier, or similar flexible natural fibers? → 9403.89
## Overlaps & pitfalls
- A cart made of bamboo may resemble wood or plastic in appearance—check material composition.
- Rattan and other fiber-based products (e.g., cane) are distinct from woven plastic or metal; avoid confusion with synthetic materials.
- If multiple materials are used (e.g., wooden frame with plastic bins), the primary structural material determines classification.
- No clear priority rule—choose based on the **main structural material**
