## Common ground
All options are catering containers used for storing, transporting, or serving food.
## Options at a glance
**3924.10 – Plastic**
- **Defining trait:** Made from synthetic polymer materials (e.g., polypropylene, polystyrene).
- **Typical examples:** Disposable lunch boxes, takeout containers, microwave-safe lids.
- **Best fit when:** Lightweight, low-cost, single-use or short-term reuse is needed; food safety and portability are priorities.
**7010.90 – Glass**
- **Defining trait:** Made from transparent, non-porous silica-based material; heat-resistant and chemically inert.
- **Typical examples:** Reusable food jars, bento boxes, serving dishes for restaurants.
- **Best fit when:** Long-term reuse, high hygiene standards, or oven/microwave use is required.
**7323.93 – Stainless steel**
- **Defining trait:** Made from corrosion-resistant metal alloy (e.g., 18/8 stainless steel); durable and thermally conductive.
- **Typical examples:** Insulated lunch pails, industrial food carriers, stackable meal trays.
- **Best fit when:** Durability, insulation, or frequent washing in commercial kitchens is essential.
## Key differences
| Feature | Plastic (3924.10) | Glass (7010.90) | Stainless Steel (7323.93) |
|------------------|-------------------|-----------------|----------------------------|
| Durability | Low | Medium (fragile) | High |
| Heat resistance | Limited | High | High |
| Reusability | Moderate | High | Very high |
| Weight | Light | Heavy | Medium-heavy |
## How to choose
- Is the container meant for single use or short-term reuse? → 3924.10
- Does it need to be microwave-safe, oven-safe, or used in high-hygiene settings? → 7010.90
- Is durability and long-term use in commercial kitchens key? → 7323.93
## Overlaps & pitfalls
A container may fit more than one category if it’s reusable and made of glass or metal, but the primary material determines classification. For example, a stainless steel lid on a plastic container still falls under 3924.10 if the main body is plastic. The defining trait is the **main material**, not accessories. If unclear, prioritize the dominant structural material
