## Options at a glance
**3926.90 – Made of plastic material**
- **Defining trait:** Constructed primarily from plastic, typically lightweight and disposable.
- **Typical examples:** Single-use plastic bulb syringes for medical or lab use.
- **Best fit when:** The product is intended for one-time use, low cost, or needs to be lightweight and shatterproof.
**7010.10 – Made of glass**
- **Defining trait:** Crafted from glass, offering high chemical resistance and clarity.
- **Typical examples:** Reusable lab syringe bulbs or medical-grade glass bulbs for precise measurements.
- **Best fit when:** The product must withstand sterilization, resist chemical degradation, or requires visual inspection of fluid.
## Key differences
| Feature | 3926.90 (Plastic) | 7010.10 (Glass) |

## How to choose
- Is the bulb made of plastic? → 3926.90
- Is it made of glass and intended for repeated use? → 7010.10
## Overlaps & pitfalls
A syringe bulb could technically be both reusable and made of plastic, but the material (plastic vs. glass) is the key differentiator. If the product is clearly plastic, use 3926.90; if glass, use 7010.10. No priority rule is implied—choose based on the primary material
