## Common ground
All options refer to glass-based products used in office environments, such as containers or decorative items.
## Options at a glance
**7013.10 – Glass ceramics**
- **Defining trait:** Made from glass-ceramic materials, which are heat-resistant and durable, often used for high-performance lab or kitchen-like office use.
- **Typical examples:** Laboratory beakers, heat-resistant glass cups, digital display enclosures.
- **Best fit when:** The product is designed to withstand high temperatures or mechanical stress beyond standard glass.
**7013.9X – Other glassware**
- **Defining trait:** Standard glass products not classified as glass ceramics; includes transparent, non-heat-resistant items common in offices.
- **Typical examples:** Water glasses, ink bottles, decorative vases, pen holders.
- **Best fit when:** The item is ordinary glass used for storage, display, or daily office use without special thermal resistance.
## Key differences
| Feature | 7013.10 – Glass ceramics | 7013.9X – Other glassware |
|---------------------|-------------------------------|----------------------------------|
| Heat resistance | High (can withstand boiling) | Low (breaks with sudden heat) |
| Material type | Glass-ceramic composite | Standard soda-lime or borosilicate glass |
| Typical use case | Lab, high-stress environments | General office storage/display |
## How to choose
- Is the glass designed to withstand boiling water or oven-like temperatures? → 7013.10
- Is it a standard drinking glass, bottle, or decorative item for daily office use? → 7013.9X
## Overlaps & pitfalls
Some items (e.g., a heat-resistant ink bottle) might fit both, but the main function determines classification. If the product is primarily used for storage and not exposed to high heat, it belongs in 7013.9X. The key is whether heat resistance is a defining feature—otherwise, default to “Other glassware.”
