Format
Crates, wooden boxes and metal stillages
Heavy, awkward and high-value parts travel in crates and stillages. Strength, blocking and export timber rules matter more than volume.
Main types
| 4C / 4D | Wooden or plywood box | UN codes for natural wood and plywood outer packaging. |
|---|---|---|
| Stillage | Steel stillage or wire mesh pallet | Returnable, stackable and often custom to the part. |
| Crate | Open timber crate | Machinery and spares; built to the load. |
What to decide
- Load path: skids, blocking and bracing for the heaviest point.
- Corrosion protection for long or sea transit.
- One-way timber versus a returnable steel fleet.
Inspection and handling
- Check for the export timber treatment mark when shipping across borders.
Rules to watch
- ISPM 15 treatment and marking for wood packaging in international trade.
