Before dispatch, confirm that the carrier accepts the box and its cold source.
Get written shipping conditions
Get written rules for outer packaging, labels, leakage and the chosen cold source. One branch acceptance is not a regular service.
Identity and delivery record
Keep the label clear of the box ID. A seal shows closure, not temperature. If logging is needed, set its position and who stops it at delivery.
Trial both directions
In a pilot, record delivery, who holds the empty box and its return. Review whether collection or deposit fits planned volume.
