## Common ground
All options refer to decorative or functional glass items, specifically small glass objects used as wine glass charms.
## Options at a glance
**7013.10 – Glass ceramics**
- **Defining trait:** Made from glass-ceramic materials, which are heat-resistant and often have enhanced durability.
- **Typical examples:** Heatproof decorative beads, labware-like charms with crystalline structure.
- **Best fit when:** The charm is explicitly made from a glass-ceramic blend (e.g., Pyroceram), not regular soda-lime glass.
**7013.9X – Other glassware**
- **Defining trait:** Made from standard glass types (e.g., soda-lime, lead crystal) without special heat resistance or ceramic composition.
- **Typical examples:** Plain colored glass beads, cut-glass charms, blown-glass trinkets.
- **Best fit when:** The charm is ordinary glass, not engineered for high heat or structural reinforcement.
## Key differences
| Feature | 7013.10 – Glass ceramics | 7013.9X – Other glassware |

## How to choose
- Is the charm made from a heat-resistant, crystalline glass-ceramic material? → 7013.10
- Is it regular blown, cut, or colored glass without special thermal properties? → 7013.9X
## Overlaps & pitfalls
Some glass charms may appear similar but differ in material composition. If unsure, check if the product is labeled as "glass-ceramic" or "heat-resistant." The main function (decoration) doesn’t determine classification—material does. No priority rule is implied; use the **defining material trait** for correct HS Code assignment
