## Common ground
All options are types of sound absorbers, designed to reduce noise by converting sound energy into heat.
## Options at a glance
**6304.9X – Made of textile material**
- **Defining trait:** Uses fabric-based materials like cotton, wool, or synthetic fibers as the primary sound-absorbing medium.
- **Typical examples:** Acoustic panels made from felt, fabric-wrapped foam, or woven textiles.
- **Best fit when:** The product is soft, flexible, and often used in rooms needing aesthetic appeal (e.g., offices, studios).
**6808.00 – Made of vegetable products**
- **Defining trait:** Constructed from natural plant-based materials such as cork, bamboo, or hemp.
- **Typical examples:** Cork tiles, bamboo acoustic panels, or fiberboard from agricultural waste.
- **Best fit when:** The product emphasizes sustainability, eco-friendliness, and natural materials.
**7019.90 – Made of glass fibers or fiberglass**
- **Defining trait:** Uses fine glass filaments to trap sound waves; known for high efficiency and durability.
- **Typical examples:** Industrial insulation panels, ceiling tiles in large buildings, HVAC duct lining.
- **Best fit when:** High-performance noise reduction is needed in commercial or industrial settings.
## Key differences
| Feature | 6304.9X (Textile) | 6808.00 (Vegetable) | 7019.90 (Glass Fiber) |
|---------------------|-------------------|---------------------|------------------------|
| Material source | Synthetic or natural fibers | Plants (e.g., cork, bamboo) | Recycled glass |
| Sound absorption | Moderate | Moderate to good | Excellent |
| Durability | Low to medium | Medium | High |
| Environmental impact| Varies | Low (biodegradable) | Higher (production energy) |
## How to choose
- Is the material primarily fabric or woven fiber? → 6304.9X
- Is it made from natural plant sources like cork or bamboo? → 6808.00
- Does it contain glass fibers or fiberglass insulation? → 7019.90
## Overlaps & pitfalls
A product could combine materials (e.g., textile-wrapped fiberglass), making it fit multiple codes. In such cases, prioritize the **main sound-absorbing material**. If uncertain, use the most dominant component. No option is inherently more accurate—context determines the correct classification
