## Common ground
All options refer to glass-based containers used for holding or dispensing powdered substances.
## Options at a glance
**7013.10 – Glass ceramics**
- **Defining trait:** Made from glass-ceramic materials, which are heat-resistant and durable.
- **Typical examples:** Laboratory powder bowls, high-temperature resistant mixing vessels.
- **Best fit when:** The bowl must withstand thermal shock or extreme temperatures.
**7013.9X – Other glassware**
- **Defining trait:** Made from standard glass (e.g., soda-lime or borosilicate), not glass-ceramic.
- **Typical examples:** Cosmetic powder compacts, kitchen spice bowls, general-purpose lab containers.
- **Best fit when:** The product is ordinary glass and does not require special heat resistance.
## Key differences
| Feature | 7013.10 – Glass ceramics | 7013.9X – Other glassware |
|---------------------|-------------------------------|----------------------------------|
| Material | Glass-ceramic (heat-resistant) | Standard glass (e.g., borosilicate) |
| Thermal resistance | High | Moderate to low |
| Typical use | Lab, industrial settings | Home, cosmetic, general use |
## How to choose
- Is the bowl designed to withstand high heat or thermal shock? → 7013.10
- Is it made from regular glass (not specially heat-resistant)? → 7013.9X
## Overlaps & pitfalls
A product might be mistaken for glass ceramics if it’s borosilicate glass, which is heat-resistant but not classified as glass-ceramic. The key distinction is material composition: glass-ceramics are crystallized glass with enhanced durability. If unsure, prioritize the **main function**: use 7013.10 only if heat resistance is a defining feature; otherwise, default to 7013.9X
