## Common ground
All options refer to shower cabin sliding doors, which are enclosure panels designed to prevent water from splashing out during a shower.
## Options at a glance
**3922.10 – Plastic material**
- **Defining trait:** Constructed primarily from plastic (e.g., acrylic or polycarbonate), often lightweight and impact-resistant.
- **Typical examples:** Acrylic shower panels, molded plastic doors with frameless design.
- **Best fit when:** The door is not made of glass, is lighter, and may have a softer appearance or be used in budget-friendly models.
**7013.9X – Glass**
- **Defining trait:** Made from transparent or tempered glass, offering clarity, durability, and a premium look.
- **Typical examples:** Tempered glass sliding doors, frameless or semi-frameless shower enclosures.

## How to choose
- Is the door made of a transparent plastic material like acrylic? → 3922.10
- Does it feel hard, heavy, and look like clear glass? → 7013.9X
## Overlaps & pitfalls
A shower door might combine both materials (e.g., glass frame with plastic panels), but the primary material determines classification. If unclear, prioritize the main structural material. The term "glass" in HS Code 7013.9X refers to tempered safety glass—common in showers—while plastic includes non-glass transparent materials. Do not assume all clear doors are glass; some acrylics mimic glass but are classified separately
