## How to choose
- Is the drum made of steel? → 7326.90
- Does it have a motorized winding system? → 8479.89
- Is it used with a winch? → 8431.10
- Does it include a socket that defines its function? → 8536.69
- Are connectors permanently attached to the cable? → 8544.42
- Is the cable insulated but without connectors? → 8544.49
- Is it made of wood (solid)? → 4415.10
- Is it made of plywood? → 4421.99
- Is it made of corrugated cardboard? → 4822.90
## Overlaps & pitfalls
- A drum with a socket may also be made of steel or wood — priority goes to **functional integration** (socket defines the product).
- An automatic winding machine (8479.89) may be made of steel, but its automation is key.
- Drums with connectors (8544.42) are always electrical and pre-wired; if no connectors, use 8544.49.
- If unsure, prioritize the **main function**: storage, automation, or electrical integration
