  • Separate mandatory certificates from documents requested only for reference.

Before purchase order

  • Resolve every deviation in writing.
  • Confirm available quantity separately from made-to-order or on-request quantity.
  • Freeze delivery location, unloading window and consignee details.

Before dispatch

  • Reconcile package count to the final order.
  • Verify identification marks remain readable after packing.
  • Record vehicle/transporter details and release time.
