## Common ground
All options refer to medical devices used to collect bodily waste from a colostomy.
## Options at a glance
**3926.90 – Made of plastic material**
- **Defining trait:** Constructed primarily from flexible plastic (e.g., polyethylene or PVC), offering lightweight, disposable use.
- **Typical examples:** Single-use, transparent plastic bags with adhesive flanges.
- **Best fit when:** Disposable, hygienic, and cost-effective solutions are needed; common in home care.
**4014.90 – Made of rubber**
- **Defining trait:** Constructed from natural or synthetic rubber, typically more durable and reusable.
- **Typical examples:** Reusable rubber pouches with adjustable straps and valves.
- **Best fit when:** Long-term use, durability, and reusability are prioritized; less common today.
## Key differences
| Feature | 3926.90 (Plastic) | 4014.90 (Rubber) |
|---------------------|--------------------------|----------------------------|
| Material | Plastic (e.g., PVC) | Natural/synthetic rubber |
| Reusability | Disposable | Reusable |
| Common use | Home care, short-term | Long-term, durable needs |
| Modern prevalence | High | Low |
## How to choose
- Is the bag intended for single use and easy disposal? → 3926.90
- Is it designed for repeated use and long-term wear? → 4014.90
## Overlaps & pitfalls
Some modern colostomy bags combine plastic and rubber components (e.g., rubber seals on plastic pouches), which may create ambiguity. However, the primary material determines classification. If unsure, prioritize the **main structural material**: if plastic dominates, use 3926.90; if rubber is central, use 4014.90. No option is inherently superior—choice depends on user needs
