## Common ground
All options refer to metal cans used for packaging food and beverages.
## Options at a glance
**7310.2X – Made of iron or steel**
- **Defining trait:** Constructed from iron or steel, often with a protective coating (e.g., tin-plated) to prevent corrosion.
- **Typical examples:** Soda cans (historically), canned vegetables, beans, and soups.
- **Best fit when:** The can is heavy-duty, commonly used for long-shelf-life products, and may have a double seam.
**7612.90 – Made of aluminium**
- **Defining trait:** Made from lightweight aluminium, typically formed into a single-piece body with a separate lid.
- **Typical examples:** Soft drink cans (e.g., cola), energy drinks, beer in pull-tab cans.
- **Best fit when:** The can is lightweight, commonly used for beverages, and designed for easy opening.

## Overlaps & pitfalls
A can may be made of aluminium but have a steel lid, or vice versa—this does not change the primary material classification. The main function (beverage vs. food) and weight are stronger indicators than minor components. If unsure, prioritize the **dominant material** of the body. Do not assume that all beverage cans are aluminium—some steel cans are used for beer
