## Common ground
All options are types of douche cans classified by their primary material.
## Options at a glance
**3924.90 – Plastic**
- **Defining trait:** Made from synthetic polymer materials, typically lightweight and flexible.

- **Typical examples:** Industrial douches, vintage medical tools.
- **Best fit when:** The product is metallic, heavy, and likely rusts over time.
**7418.20 – Copper**

- **Best fit when:** The product is light, shiny, and resistant to rust.
**7907.00 – Zinc**

## Key differences
| Material | Weight | Durability | Surface Finish | Corrosion Resistance |
|--------------|----------|------------|------------------------|------------------------|
| Plastic | Light | Low | Smooth, molded | High (if not degraded) |
| Porcelain | Heavy | Medium | Glazed, glossy | Very high |
| Ceramic | Medium | Low | Matte or unglazed | Low |
| Iron/Steel | Heavy | Medium | Dull, rusty if untreated | Low (unless coated) |
| Copper | Medium | High | Warm, tarnishes over time | Moderate |
| Aluminium | Light | High | Shiny, anodized | High |
| Zinc | Medium | Medium | Bluish-gray, coated | High (if galvanized) |
## How to choose
- Is the product made of plastic? → 3924.90
- Is it glazed and hard like pottery? → 6911.90
- Is it unglazed or rough-textured clay? → 6912.00
- Is it heavy, metallic, and likely to rust? → 7324.90
- Is it reddish-brown and antimicrobial? → 7418.20
- Is it lightweight, shiny, and non-rusting? → 7615.10
- Is it bluish-gray and coated for protection? → 7907.00
## Overlaps & pitfalls
- Porcelain (6911.90) and ceramic (6912.00) can overlap; porcelain is a type of ceramic, but the HS code distinguishes them by finish and density. Choose based on surface: glazed = porcelain, unglazed = ceramic.
- Copper and zinc may be confused due to similar uses; copper is reddish, zinc is bluish-gray.
- No option explicitly covers mixed materials—choose based on the **dominant material**
