## Common ground
All options are garden beds made from different materials, used for growing plants in outdoor or controlled environments.
## Options at a glance
**9403.20 – Base metal**
- **Defining trait:** Constructed primarily from steel, iron, or other metallic alloys, often rust-resistant or coated.
- **Typical examples:** Galvanized steel raised beds, metal frame planters.
- **Best fit when:** Durability and long-term stability are priorities; for heavy soil or high-wind areas.
**9403.60 – Wood**
- **Defining trait:** Made from natural wood (e.g., cedar, pine), often untreated or weather-resistant.
- **Typical examples:** Wooden raised garden beds, rustic planters.
- **Best fit when:** Aesthetic appeal and natural look are important; for organic gardening with minimal chemical exposure.
**9403.70 – Plastic material**
- **Defining trait:** Manufactured from synthetic polymers like polyethylene or recycled plastic.
- **Typical examples:** Lightweight, molded garden beds, modular planters.
- **Best fit when:** Lightweight, low maintenance, and weather-resistant options are needed; ideal for balconies or small spaces.
**9403.82 – Bamboo**
- **Defining trait:** Made from bamboo, a fast-growing natural fiber known for strength and sustainability.
- **Typical examples:** Bamboo-framed raised beds, eco-friendly planters.
- **Best fit when:** Eco-conscious design and sustainable materials are key; for gardeners seeking renewable resources.
## Key differences
| Feature | Base metal | Wood | Plastic | Bamboo |
|------------------|----------------|----------------|----------------|------------------|
| Material source | Industrial metals | Natural trees | Synthetic polymer | Renewable plant |
| Durability | High | Medium (degrades) | High | Medium-high |
| Weight | Heavy | Medium | Light | Light-medium |
| Eco-friendliness | Low to medium | Medium | Low (plastic waste) | High |
## How to choose
- Is the bed made of steel, iron, or coated metal? → 9403.20
- Is it primarily made of untreated or natural wood? → 9403.60
- Is it molded from plastic or recycled polymer? → 9403.70
- Is it constructed from bamboo poles or woven bamboo? → 9403.82
## Overlaps & pitfalls
A bed with a wooden frame and plastic lining could fit both 9403.60 and 9403.70. Similarly, bamboo may be treated with plastic coatings. If multiple materials are used, prioritize the **main structural material**. No option is vague—each clearly defines a distinct material type
