## Key differences
| Option | Material Type | Flexibility | Transparency | Common Use Case |
|-------|----------------|-------------|--------------|------------------|
| 3925.30 | Plastic | Flexible but stiff | Clear/semi-transparent | Indoor decorative, waterproof |
| 4421.99 | Wood | Rigid | Partially opaque | Decorative, room dividers |
| 6303 | Textile | Soft, drapey | Sheer | Home curtains, light filtering |

## How to choose
- Is the curtain made of plastic? → 3925.30
- Is it made of visible wood slats? → 4421.99
- Is it soft, flowy, and made from fabric (e.g., polyester)? → 6303
- Is it made of glass fibers or used in high-heat settings? → 7019.6X/7X
- Is it metallic, shiny, and rigid? → 7616.99
## Overlaps & pitfalls
- A plastic tulle curtain might resemble textile but is stiffer and waterproof — prioritize material over look.
- Glass fiber and aluminum curtains may both be used in architecture; distinguish by material feel (glass = brittle, aluminum = flexible).
- If unsure, use the **main function**: decoration → 6303; light control → 7616.99 or 4421.99; durability → 7019.6X/7X
