## Common ground
All options are monitor stands or holders, designed to support a display screen.
## Options at a glance
**3926.90 – Made of plastic material**
- **Defining trait:** Constructed primarily from synthetic polymer materials (e.g., ABS, polycarbonate).
- **Typical examples:** Lightweight desktop stands with adjustable height, foldable plastic bases.
- **Best fit when:** The stand is lightweight, mass-produced, and cost-sensitive; often used in home or office settings.
**4420.90 – Made of wood**
- **Defining trait:** Crafted from natural wood (e.g., pine, oak), often with a solid or laminated structure.
- **Typical examples:** Wooden desk mounts with minimalist design, vintage-style monitor risers.
- **Best fit when:** Aesthetic appeal, natural material preference, or high-end interior design is prioritized.
**7326.90 – Made of iron or steel**
- **Defining trait:** Built from ferrous metals, offering high strength and durability.
- **Typical examples:** Heavy-duty industrial stands, adjustable height arms with metal frames.
- **Best fit when:** The stand must support large or heavy monitors, or withstand frequent adjustments.
**7616.99 – Made of aluminium**
- **Defining trait:** Constructed from lightweight yet strong aluminum alloy, often anodized.
- **Typical examples:** Sleek, modern monitor arms, minimalist wall mounts with smooth motion.
- **Best fit when:** A balance of strength, lightness, and modern appearance is needed (e.g., in creative studios).
## Key differences
| Feature | Plastic | Wood | Iron/Steel | Aluminium |
|------------------|---------------|--------------|----------------|----------------|
| Weight | Light | Medium-heavy | Very heavy | Light |
| Durability | Low–medium | Medium | High | High |
| Aesthetic | Modern, basic | Natural, warm| Industrial, rugged | Sleek, modern |
| Adjustability | Limited | Limited | High | Very high |
## How to choose
- Is the stand made of a synthetic polymer (e.g., ABS, PVC)? → 3926.90
- Is it made from natural wood (e.g., oak, pine)? → 4420.90
- Does it feel heavy and use iron or steel? → 7326.90
- Is it lightweight with a smooth, modern finish? → 7616.99
## Overlaps & pitfalls
A stand may combine materials (e.g., aluminum frame with plastic parts), but the **primary structural material** determines the HS Code. If unclear, prioritize the main load-bearing component. No option is inherently more correct—choose based on material composition
