Heavy steel plates and coils require strapping solutions selected for their specific loads and transport conditions.
Make sure all documents are prepared correctly:
| Document Name | Why It Matters | When to Request |
|---|---|---|
| Commercial Invoice | Required for customs clearance | Before shipment |
| Packing List | Details cargo and quantity | Before shipment |
| Mill Test Certificate (MTC) | Verifies material quality | Before balance payment / before loading |
| Bill of Lading | Proof of shipment | After shipment |
Accurate documentation ensures smooth customs clearance and avoids unnecessary delays.
