## How to choose
- Is the trolley made of steel or iron? → 9403.10
- Is it primarily wood (solid or panel)? → 9403.30
- Is it mostly plastic (e.g., molded, lightweight)? → 9403.70
- Is it made from bamboo? → 9403.82
- Is it woven from rattan? → 9403.83
- Does it use cane, osier, or similar natural fiber? → 9403.89
## Overlaps & pitfalls
- A trolley with a bamboo frame and plastic drawers may blend 9403.82 and 9403.70; prioritize the **main structural material**.
- "Other materials" (9403.89) is broad—avoid if the material is clearly bamboo or rattan.
- If unsure, ask: *What is the primary material of the frame and main body?*
