## Key differences
| Feature | 3926.30 (Plastic) | 8302.49 (Base Metal) |
|------------------|--------------------------|----------------------------|

## How to choose
- Is the fitting made of plastic? → 3926.30
- Is it made of metal (like steel, brass, iron)? → 8302.49
## Overlaps & pitfalls
A product may combine both materials (e.g., a metal hinge with plastic inserts), but the primary material determines the HS Code. If unclear, prioritize the **main structural material**. The term "base metal" includes steel and brass—do not assume it means only iron
