## Common ground
All options are types of sun screens made from different materials, used to block or reduce sunlight.
## Options at a glance
**6304.9X,6307.90 – Made of textile material**
- **Defining trait:** Constructed from fabric or woven textiles (e.g., canvas, polyester).
- **Typical examples:** Outdoor shade sails, patio curtains, retractable sun shades.
- **Best fit when:** Flexibility, ease of installation, and aesthetic design are priorities.
**7019.6X,7019.7X,7019.90 – Made of glass fibers or fiberglass**
- **Defining trait:** Uses rigid, durable glass fiber mesh or fabric for high heat and UV resistance.
- **Typical examples:** Industrial sun screens, greenhouse covers, architectural shading panels.
- **Best fit when:** Long-term durability, fire resistance, and weatherproofing are essential.
**7616.99 – Made of aluminium**
- **Defining trait:** Constructed from lightweight, corrosion-resistant aluminum slats or frames.
- **Typical examples:** Louvered sun screens, adjustable window shades, balcony shading systems.
- **Best fit when:** Structural strength, adjustability, and modern appearance are key.
## Key differences
| Feature | Textile | Glass fiber | Aluminium |

- Does it use aluminum slats or frames with adjustable angles? → 7616.99
## Overlaps & pitfalls
A sun screen may combine materials (e.g., aluminum frame with textile fabric), but the **main structural material** determines the correct HS Code. If unsure, prioritize the primary functional component. The term "sun screen" can refer to both flexible and rigid types—clarify based on material and use
