## Common ground
All options refer to shower cabins, which are enclosed bathing spaces typically used in bathrooms.
## Options at a glance
**3922.10 – Made of plastic material**
- **Defining trait:** Constructed primarily from synthetic plastic (e.g., acrylic or PVC), often molded as a single unit.
- **Typical examples:** Acrylic shower enclosures, prefabricated plastic cabins with rigid panels.
- **Best fit when:** The cabin is lightweight, low-cost, and has a smooth, molded surface without visible metal framing.
**7020.00 – Made of glass**
- **Defining trait:** Features transparent or translucent glass panels (usually tempered), often with minimal or no metal frame.
- **Typical examples:** Frameless glass shower doors, semi-frameless enclosures.
- **Best fit when:** The cabin emphasizes visibility, modern design, and a sleek, open feel.
**7610.90 – Made of aluminium**
- **Defining trait:** Uses aluminium for structural framing or support, often combined with glass or plastic panels.
- **Typical examples:** Glass shower cabins with aluminium frames, modular cabins with aluminium profiles.
- **Best fit when:** The cabin has visible metal supports, is designed for durability and stability, or includes sliding/hinged mechanisms.
## Key differences
| Feature | 3922.10 (Plastic) | 7020.00 (Glass) | 7610.90 (Aluminium) |
|------------------|-------------------|-----------------|---------------------|
| Primary material | Plastic (acrylic/PVC) | Tempered glass | Aluminium frame |
| Visibility | Opaque or translucent | Transparent | Depends on panel type |
| Structural role | Self-supporting | Needs support | Main structural element |
## How to choose
- Is the cabin made of a rigid, molded plastic (like acrylic)? → 3922.10
- Does it use glass panels as the main enclosure? → 7020.00
- Is there visible aluminium framing or structure? → 7610.90
## Overlaps & pitfalls
A shower cabin may combine materials (e.g., glass with aluminium frame), which fits both 7020.00 and 7610.90. In such cases, the **main structural material** determines the correct HS Code. If the frame is dominant, use 7610.90; if the panels are the key feature, use 7020.00. Do not assume plastic cabins are always acrylic—some may be PVC, but both fall under 3922.10
