## Common ground
All options refer to play pens—folding or fixed enclosures for children—classified by their primary material.
## Options at a glance
**9403.20 – Base metal**
- **Defining trait:** Constructed primarily from metals like steel or aluminum.
- **Typical examples:** Metal-framed play pens with mesh sides.
- **Best fit when:** The frame is rigid, durable, and made of metal (e.g., foldable baby gates with metal joints).
**9403.60 – Wood**
- **Defining trait:** Made predominantly from solid or laminated wood.
- **Typical examples:** Wooden play pens with slats or panels.
- **Best fit when:** The structure uses visible, solid wooden components (e.g., carved or joined wooden bars).
**9403.70 – Plastic material**
- **Defining trait:** Primarily made from plastic (e.g., polypropylene, PVC), often molded.
- **Typical examples:** Lightweight, colorful plastic play pens with snap-together parts.
- **Best fit when:** The product is molded, lightweight, and non-metallic, with no wood or natural fiber visible.
**9403.82 – Bamboo**
- **Defining trait:** Made from bamboo, a fast-growing grass used as a structural material.
- **Typical examples:** Eco-friendly play pens using bamboo poles or strips.
- **Best fit when:** The frame or panels are visibly made from bamboo (e.g., natural bamboo rods).

- **Defining trait:** Constructed from rattan, a tropical climbing palm used in weaving.
- **Typical examples:** Woven play pens with flexible rattan frames or panels.
- **Best fit when:** The product uses woven or pliable rattan strands (e.g., basket-like structure).
**9403.89 – Other materials (cane, osier, etc.)**
- **Defining trait:** Made from natural fibers like cane, osier (willow), or similar plant materials.
- **Typical examples:** Woven play pens using reed or willow rods.
- **Best fit when:** The material is not bamboo or rattan but another flexible natural fiber used in weaving.

## How to choose
- Is the frame made of metal (e.g., steel, aluminum)? → 9403.20
- Is it made of solid or laminated wood? → 9403.60
- Is it molded plastic with no visible natural material? → 9403.70
- Are the main components bamboo rods or strips? → 9403.82
- Is it woven from rattan strands? → 9403.83
- Is it made from cane, willow, or similar flexible plant fiber? → 9403.89
## Overlaps & pitfalls
- Bamboo and rattan are both natural fibers but differ in origin and structure; avoid confusion.
- Rattan and other materials (cane/osier) may look similar—check if it’s specifically rattan.
- If a pen uses multiple materials (e.g., plastic frame with bamboo sides), prioritize the **main structural material**.
- No clear priority rule: choose based on the product’s **defining feature**
