## Common ground
All options are drain hair catchers, devices used to prevent hair and debris from clogging drains.
## Options at a glance
**3924.90 – Plastic material**
- **Defining trait:** Made from plastic, typically lightweight and corrosion-resistant.
- **Typical examples:** Silicone mesh strainer, molded polypropylene drain cover.
- **Best fit when:** You need a low-cost, rust-free, easy-to-clean option for showers or sinks.
**7324.90 – Iron or steel**
- **Defining trait:** Made from metal (iron/steel), usually more durable and heavier.
- **Typical examples:** Stainless steel drain grate, cast iron hair trap.
- **Best fit when:** You need long-term durability, high load resistance, or a heavy-duty solution for commercial use.
## Key differences
| Feature | 3924.90 (Plastic) | 7324.90 (Iron/Steel) |
|------------------|--------------------------|----------------------------|
| Material | Plastic | Iron or steel |
| Durability | Moderate | High |
| Corrosion risk | Low | Higher (unless stainless) |
| Weight | Light | Heavy |
## How to choose
- Is the device made of plastic? → 3924.90
- Is it made of iron or steel (especially stainless)? → 7324.90
## Overlaps & pitfalls
A drain hair catcher could be made of stainless steel, which is a type of iron/steel, so it fits 7324.90. Plastic versions may include metal reinforcements, but the primary material determines the HS Code. If unsure, prioritize the **main structural material**. Do not assume all metal catchers are in 7324.90—only those made of iron or steel (not aluminum or copper)
