## Common ground
All options refer to hollow glass products, such as containers or vessels made from glass.
## Options at a glance
**7013.10 – Glass ceramics**
- **Defining trait:** Made from glass-ceramic materials, which are heat-resistant and durable due to crystalline structure.
- **Typical examples:** Laboratory beakers, ovenware, cookware.
- **Best fit when:** The product is designed for high thermal stress or extreme temperature changes.
**7013.9X – Other glassware**
- **Defining trait:** Made from standard soda-lime or borosilicate glass, not classified as glass ceramics.
- **Typical examples:** Drinking glasses, bottles, jars, vials.
- **Best fit when:** The product is ordinary hollow glass used for storage, serving, or everyday use.
## Key differences
| Feature | 7013.10 – Glass ceramics | 7013.9X – Other glassware |
|---------------------|-------------------------------|----------------------------------|
| Material type | Glass-ceramic (crystalline) | Standard glass (amorphous) |
| Heat resistance | Very high | Moderate to low |
| Typical use | Lab, kitchen, industrial | Household, packaging, storage |
## How to choose
- Is the product designed to withstand sudden temperature changes or high heat? → 7013.10
- Is it a standard container for liquids or food, not meant for extreme heat? → 7013.9X
## Overlaps & pitfalls
Some borosilicate glassware (e.g., lab glass) may resemble glass ceramics but is still classified under "other glassware" unless explicitly labeled as glass-ceramic. The term “glass ceramics” refers to a specific material class, not just heat-resistant glass. If unsure, prioritize the **material composition** over function
