## Common ground
All options are vacuum insulation panels (VIPs), high-performance thermal insulators using a vacuum-sealed core to minimize heat transfer.
## Options at a glance
**6806.90 – Mineral-based VIPs**
- **Defining trait:** Core made from mineral materials like perlite or rock wool, not specifically glass-based.
- **Typical examples:** VIPs with mineral foam or granular mineral cores.
- **Best fit when:** The product uses non-glass mineral insulation material (e.g., expanded perlite).
**7019.80 – Glass wool-based VIPs**
- **Defining trait:** Core made from glass wool (a fibrous, flexible form of glass insulation).
- **Typical examples:** VIPs using standard glass wool mats as the core material.
- **Best fit when:** The product uses a felt-like or batt-style glass wool core.
**7019.90 – Glass fibre-based VIPs (other than glass wool)**
- **Defining trait:** Core made from non-woven glass fibres not classified as glass wool (e.g., fine, rigid, or engineered fibres).
- **Typical examples:** VIPs with high-density, spun or blown glass fibre mats.
- **Best fit when:** The core is a more structured or specialized glass fibre product, not standard wool.
## Key differences
| Feature | 6806.90 (Mineral) | 7019.80 (Glass wool) | 7019.90 (Other glass fibres) |
|---------------------|-------------------|------------------------|-------------------------------|
| Core material | Non-glass minerals | Glass wool (flexible) | Engineered glass fibres |
| Texture/structure | Granular or rigid | Fibrous, soft | Dense, uniform |
| Typical use case | Industrial insulation | Building insulation | High-performance applications |
## How to choose
- Is the core made of non-glass mineral material (e.g., perlite)? → 6806.90
- Is the core a standard glass wool mat? → 7019.80
- Is the core a fine, rigid, or engineered glass fibre not classified as wool? → 7019.90
## Overlaps & pitfalls
Glass wool and other glass fibres can be similar; if unsure, check whether the material is described as “wool” in technical specs. 6806.90 may overlap with mineral-based VIPs that include glass components, but only if they are not primarily glass-based. **No clear priority**—choose based on the **main core material**
