## Common ground
All options refer to metal pins used for fastening, primarily in clothing or industrial applications.
## Options at a glance
**7319.40 – Made of iron or steel**
- **Defining trait:** Constructed from ferrous metals, typically offering high strength and durability.
- **Typical examples:** Standard safety pins, industrial clamps, wire fasteners.
- **Best fit when:** The pin is strong, rust-resistant (if coated), and used in everyday or heavy-duty applications.
**7419 – Made of copper**
- **Defining trait:** Crafted from non-ferrous metal, valued for conductivity, corrosion resistance, and aesthetic appeal.
- **Typical examples:** Decorative pins, electrical connectors, jewelry fasteners.
- **Best fit when:** The pin is used in electronics, decorative items, or where non-magnetic properties are needed.
## Key differences
| Feature | 7319.40 (Iron/Steel) | 7419 (Copper) |
|---------------------|------------------------|------------------------|
| Material type | Ferrous (magnetic) | Non-ferrous (non-magnetic) |
| Common use | Functional fastening | Decorative or electrical |
| Corrosion resistance| Low (unless coated) | High |
## How to choose
- Is the pin primarily used for clothing or general fastening? → 7319.40
- Is it used in electronics, jewelry, or decorative items? → 7419
## Overlaps & pitfalls
A copper pin may be used as a safety pin (e.g., in fashion), and a steel pin might be decorative if polished—so material alone isn’t always decisive. If the product is both functional and decorative, prioritize based on **main function**: use 7319.40 for utility, 7419 for aesthetics or conductivity. The HS codes do not specify priority; choose based on the product’s primary purpose
