## Common ground
All options are types of cable glands, which are devices used to secure and seal cables entering electrical enclosures.
## Options at a glance
**3926.90 – Plastic material**
- **Defining trait:** Made from non-metallic, typically thermoplastic or thermosetting resin.
- **Typical examples:** Nylon, polyamide, or PVC cable glands.
- **Best fit when:** Used in corrosive environments, lightweight applications, or where electrical insulation is critical.
**7326.90 – Iron or steel**
- **Defining trait:** Constructed from ferrous metals, often with galvanization for corrosion resistance.
- **Typical examples:** Galvanized steel or cast iron cable glands.
- **Best fit when:** High mechanical strength, durability, or grounding is required in industrial settings.
**7419.80 – Copper**
- **Defining trait:** Made from copper, offering excellent electrical conductivity and corrosion resistance.
- **Typical examples:** Copper-clad or solid copper cable glands for high-end electrical systems.
- **Best fit when:** Superior grounding, anti-corrosion needs, or use in sensitive electronic equipment.
## Key differences
| Feature | 3926.90 (Plastic) | 7326.90 (Iron/Steel) | 7419.80 (Copper) |
|------------------|-------------------|------------------------|------------------|
| Material | Non-metallic | Ferrous metal | Non-ferrous metal |
| Conductivity | Insulating | Low (unless coated) | High |
| Corrosion resistance | Good (varies) | Moderate (with coating)| Excellent |
| Typical use | Indoor, sensitive | Industrial, rugged | Precision, high-end |
## How to choose
- Is the gland made of plastic? → 3926.90
- Is it made of iron or steel (e.g., galvanized)? → 7326.90
- Is it made of copper (e.g., solid or cladded)? → 7419.80
## Overlaps & pitfalls
A cable gland may combine materials (e.g., copper body with plastic insert), but the **primary material** determines the HS Code. If unclear, prioritize the main structural material. No option is vague—each clearly defines a distinct material type
