## Common ground
All options are types of reels used for storing or transporting cables and piping, differing only in material.
## Options at a glance
**3923.40 – Plastic**
- **Defining trait:** Made from synthetic polymer materials, typically lightweight and resistant to moisture and corrosion.
- **Typical examples:** Plastic cable drums, polyethylene pipe reels.
- **Best fit when:** The reel is used outdoors, in wet environments, or where weight and durability matter.
**4421.99 – Wood**
- **Defining trait:** Constructed from natural wood, often treated for outdoor use; heavier but eco-friendly and sturdy.
- **Typical examples:** Wooden cable drums, timber pipe reels.
- **Best fit when:** The reel needs high structural strength or is used in traditional/eco-conscious settings.
**4822 – Paper or paperboard**
- **Defining trait:** Made from recyclable paper materials; lightweight and low-cost but not durable for heavy use.
- **Typical examples:** Disposable cable reels, packaging reels for short-term transport.
- **Best fit when:** Temporary storage, shipping, or low-load applications.
**7017.90 – Glass**
- **Defining trait:** Made from glass; highly transparent and chemically inert but fragile and heavy.
- **Typical examples:** Lab-grade cable reels for sensitive environments (rare).
- **Best fit when:** Specialized use in cleanrooms or labs where contamination must be avoided.
**7326.90 – Iron or steel**
- **Defining trait:** Made from ferrous metals; extremely strong and durable, but heavy and prone to rust without coating.
- **Typical examples:** Industrial cable reels, heavy-duty pipe reels.
- **Best fit when:** High-load, industrial, or long-term outdoor use.
## Key differences
| Material | Weight | Durability | Corrosion Resistance | Typical Use Case |
|--------------|----------|------------|------------------------|----------------------------|
| Plastic | Low | Medium | High | General-purpose, outdoor |
| Wood | Medium | High | Low (unless treated) | Traditional, eco-use |
| Paperboard | Very low | Low | None | Temporary, shipping |
| Glass | High | Low | Very high | Specialized labs |
| Iron/Steel | High | Very high | Low (unless coated) | Industrial, heavy-duty |
## How to choose
- Is the reel used in wet or outdoor conditions? → 3923.40 or 7326.90
- Is it for temporary or low-load use? → 4822
- Does it need high strength and long-term durability? → 7326.90
- Is it used in a cleanroom or lab setting? → 7017.90
## Overlaps & pitfalls
A reel may combine materials (e.g., steel frame with plastic spools), but the primary material determines classification. The term "reel" applies to all, but function and environment are key. No option is clearly prioritized—choose based on the **main structural material**
