## Common ground
All options are medical waste containers designed for safe storage and disposal of biohazardous materials.
## Options at a glance
**3926.90 – Plastic material**
- **Defining trait:** Made from durable, non-corrosive plastic; often single-use or disposable.
- **Typical examples:** Disposable red bags in rigid plastic bins, puncture-resistant plastic sharps containers.
- **Best fit when:** Need lightweight, cost-effective, and easy-to-dispose-of containers for short-term use.
**7323.9X – Iron or steel**
- **Defining trait:** Made from heavy-duty ferrous metal; resistant to impact and puncture; reusable.
- **Typical examples:** Reusable metal bins with locking lids, industrial-grade waste containers.
- **Best fit when:** High-volume, long-term use in hospitals or labs requiring durability and reusability.
**7615.20 – Aluminium**
- **Defining trait:** Lightweight yet strong; corrosion-resistant; recyclable; often used for specialized applications.
- **Typical examples:** Portable medical waste bins, lightweight sharps containers for mobile clinics.
- **Best fit when:** Need a balance of strength, light weight, and recyclability in temporary or transportable settings.
## Key differences
| Feature | 3926.90 (Plastic) | 7323.9X (Iron/Steel) | 7615.20 (Aluminium) |
|------------------|-------------------|------------------------|-----------------------|
| Weight | Light | Heavy | Light |
| Reusability | Low (single-use) | High | Medium to high |
| Corrosion resistance | Moderate | Low (rusts) | High |
| Typical use | Short-term | Long-term, heavy-duty | Mobile/transportable |
## How to choose
- Is the container meant for single-use or short-term disposal? → 3926.90
- Does it need to withstand heavy use and repeated cleaning? → 7323.9X
- Is portability and corrosion resistance a priority? → 7615.20
## Overlaps & pitfalls
A container may combine traits (e.g., an aluminium bin with plastic liner). The main function—disposal type, frequency, and environment—should determine the choice. If not specified, prioritize based on **primary use**: disposable → plastic; durable/reusable → steel; lightweight/transportable → aluminium
