## Common ground
All are wine decanters—vessels used to transfer and aerate wine before serving.
## Options at a glance
**3924.10 – Plastic**
- **Defining trait:** Made from synthetic polymer material, typically lightweight and shatterproof.
- **Typical examples:** Disposable plastic decanters, budget-friendly household versions.
- **Best fit when:** Durability and low cost are priorities; not for long-term or formal use.
**7013.10,7013.4X – Glass**
- **Defining trait:** Made from transparent silica-based material, often crystal or borosilicate glass, allowing visual inspection of wine clarity and aging.
- **Typical examples:** High-end decanters, traditional wine aerators, stemware-style decanters.

## How to choose
- Is the decanter meant to be reused for years? → 7013.10,7013.4X
- Is it intended for one-time or casual use? → 3924.10
- Does appearance matter (e.g., for gifting or dining)? → 7013.10,7013.4X
## Overlaps & pitfalls
A plastic decanter may mimic glass in shape and function but lacks the visual clarity and perceived value of real glass. While both can aerate wine, glass is preferred for serious wine service. If the product is clearly labeled as "glass" or "crystal," use 7013.10,7013.4X even if it has a plastic base (e.g., lid). The main function—wine aeration and presentation—should determine the choice; prioritize material over form
