## Common ground
All options are types of planting trays defined by their material composition.
## Options at a glance
**3926.90 – Plastic material**
- **Defining trait:** Made from synthetic polymer materials, typically reusable and moisture-resistant.
- **Typical examples:** Polypropylene seedling trays, nursery pots with drainage holes.
- **Best fit when:** The tray is lightweight, molded, and designed for repeated use in greenhouses or indoor gardening.
**4602.19 – Plaiting materials, basketwork or wickerwork**
- **Defining trait:** Constructed from woven natural fibers like bamboo, rattan, or straw.
- **Typical examples:** Handwoven bamboo seed trays, rustic garden planters made of reeds.
- **Best fit when:** The tray has a natural, handmade appearance and is used in eco-friendly or decorative gardening.
**6811.89 – Asbestos cement or cellulose fiber cement**
- **Defining trait:** Made from cement-based composite materials; durable but heavy and not commonly used for planting trays.
- **Typical examples:** Industrial-grade plant containers, rarely seen in horticulture due to material restrictions.
- **Best fit when:** The tray is extremely durable, non-biodegradable, and intended for long-term outdoor use (though asbestos cement is now banned in most countries).
## Key differences
| Feature | 3926.90 (Plastic) | 4602.19 (Basketwork) | 6811.89 (Cement) |
|---------------------|-------------------|------------------------|------------------|
| Material origin | Synthetic | Natural fibers | Inorganic composite |
| Durability | Moderate to high | Low to moderate | Very high |
| Common use | Indoor/outdoor | Decorative, eco-gardens| Industrial |
| Environmental impact| High (non-biodeg.)| Low (biodegradable) | High (toxic risk) |
## How to choose
- Is the tray made of molded plastic? → 3926.90
- Is it woven from bamboo, reed, or similar natural material? → 4602.19
- Is it heavy, rigid, and made of cement-like material? → 6811.89
## Overlaps & pitfalls
- A tray made of recycled plastic might resemble a woven design but still falls under 3926.90.
- Cement-based trays are rare; asbestos cement is banned in most countries—verify material safety.
- If multiple traits apply (e.g., plastic with natural texture), prioritize the **main structural material**.
- No clear priority rule given—choose based on the product’s **defining material**
