## Common ground
All are metal-based scouring or polishing pads used for cleaning surfaces.
## Options at a glance
**7323.10 – Iron or steel**
- **Defining trait:** Made from ferrous metals, typically hard and durable with moderate scratch resistance.
- **Typical examples:** Steel wool pads, wire scourers for pots and pans.
- **Best fit when:** High abrasion is needed; used on tough stains or heavy-duty cleaning tasks.
**7418.10 – Copper**
- **Defining trait:** Made from copper, known for softness and non-magnetic properties; can leave a slight residue but effective for polishing.
- **Typical examples:** Copper scouring pads for delicate metal surfaces (e.g., brass or silver).
- **Best fit when:** Polishing or cleaning sensitive metals without scratching.
**7615.10 – Aluminium**
- **Defining trait:** Made from lightweight, non-corrosive aluminium; softer than iron/steel and less abrasive.
- **Typical examples:** Soft scouring pads for non-stick cookware or delicate surfaces.
- **Best fit when:** Gentle cleaning is required to avoid surface damage.

- Is it lightweight, non-magnetic, and used on sensitive surfaces? → 7615.10
## Overlaps & pitfalls
A pad may combine materials (e.g., steel with copper coating), but the main metal determines classification. If unclear, prioritize the dominant material by weight or function. No option is inherently more accurate—choose based on the primary metal used
