## Common ground
All options refer to decorative glass items, specifically ornamental glass balls.
## Options at a glance
**7013.10 – Glass ceramics**
- **Defining trait:** Made from glass-ceramic materials, which are heat-resistant and often have a crystalline structure.
- **Typical examples:** Heatproof decorative orbs, labware-style ornaments, high-durability holiday balls.
- **Best fit when:** The ball is explicitly labeled as "glass-ceramic" or designed for high thermal resistance (e.g., candle holders with glass-ceramic shells).
**7013.9X – Other glassware**
- **Defining trait:** Standard soda-lime or lead glass, not classified as glass-ceramic; includes most common decorative glass items.
- **Typical examples:** Traditional Christmas tree ornaments, blown-glass paperweights, colored hanging balls.
- **Best fit when:** The item is ordinary glass, commonly used in home decor and not heat-resistant.
## Key differences
| Feature | 7013.10 – Glass ceramics | 7013.9X – Other glassware |
|---------------------|-------------------------------|----------------------------------|
| Material type | Glass-ceramic (crystalline) | Standard soda-lime or lead glass |
| Heat resistance | High | Low to moderate |
| Typical use | Functional decor, heat exposure | Purely decorative |
## How to choose
- Is the ball made from a heat-resistant, crystalline glass material? → 7013.10
- Is it standard blown or molded glass used only for decoration? → 7013.9X
## Overlaps & pitfalls
Some ornamental balls may appear similar but differ in material; if unsure, check product specs. "Glass ceramics" is a specific technical category—do not assume all durable glass qualifies. If the item is both heat-resistant and decorative, prioritize **7013.10** only if it's explicitly made from glass-ceramic. Otherwise, default to **7013.9X** for general ornamental use
