## Common ground
All options refer to badge holders made from different metallic or plastic materials.
## Options at a glance
**3926.90 – Plastic material**
- **Defining trait:** Made primarily from synthetic resin (plastic), often lightweight and flexible.
- **Typical examples:** Clear plastic badge holders, lanyard clips, snap-on plastic cases.
- **Best fit when:** The holder is transparent, thin, or molded from plastic with no metal parts.
**7326.90 – Iron or steel**
- **Defining trait:** Constructed from ferrous metals (iron or steel), typically rigid and durable.
- **Typical examples:** Heavy-duty badge holders with metal frames, industrial ID clips, steel-backed holders.
- **Best fit when:** The holder is metallic, solid, and visibly made of iron or steel.
**8308.90 – Base metal**
- **Defining trait:** Made from non-ferrous base metals (e.g., brass, copper, aluminum), often used for decorative or corrosion-resistant finishes.
- **Typical examples:** Brass badge holders, aluminum ID clips, gold-plated metal cases.
- **Best fit when:** The holder is metallic but not iron/steel, and has a non-ferrous appearance or finish.

## How to choose
1. Is it made of plastic (e.g., clear, flexible, molded)? → 3926.90
2. Is it made of iron or steel (e.g., heavy, magnetic, gray)? → 7326.90
3. Is it metal but not iron/steel (e.g., brass, copper, aluminum, shiny finish)? → 8308.90
## Overlaps & pitfalls
- A badge holder with a plastic body and steel clip may fit both 3926.90 and 7326.90. In such cases, use the **main material** (e.g., if plastic dominates, choose 3926.90).
- "Base metal" includes copper, aluminum, etc.—not just "cheap" metals. Avoid assuming it means low quality.
- If unsure, prioritize the **primary structural material** over small components
