A next-day service does not establish a 24-hour product-temperature result. Build the clock from packing to suitable receiving storage, then confirm the packout evidence covers that exposure. Use the actual coolant loading specification rather than a quantity calculated from box volume alone.
Fill in the actual time window
| Event | Information to confirm |
|---|---|
| Packing | When prepared product and coolant are assembled. |
| Pickup | The planned collection and latest acceptable handoff under the shipping plan. |
| Transit | The actual service and any relevant transfer or waiting period. |
| Receipt | When an available person can take custody. |
| Storage | When the product reaches the required receiving conditions. |
Do not count only the time between the first and last tracking scans. If collection slips, revise the complete exposure before assuming the original next-day plan still applies.
Release a prepared packout to the packing line
- Confirm the product identity and its actual temperature limits.
- Check that container, separators and coolant match the accepted configuration.
- Confirm components reached the specified starting state.
- Measure the actual dry-ice loading mass.
- Check coolant positions and product load against the drawing.
- Preserve the manufacturer-permitted gas-release arrangement.
Dry ice is not an automatic choice for refrigerated medicines or other products damaged by freezing. The intended product conditions must support its use.
Use a dispatch record rather than a volume rule
Record packing time, payload, coolant form and mass, and the component identities needed to reproduce the arrangement. Keep preparation deviations visible rather than compensating with an untested extra amount of coolant.
Box volume does not capture insulation, closure, product geometry or route exposure. Use the dry ice quantity planning guide to develop a trial, and use the accepted loading result in the daily worksheet.
Define the action if pickup or receipt changes
Set a decision point from the shipping plan and supporting evidence. If the revised exposure is outside that plan, hold the product under suitable controlled conditions and arrange an assessed alternative. Do not simply restart the clock by printing a new label.

Frequently asked questions
Does overnight mean less than 24 hours from packing?
Not necessarily. Dispatch waiting and receiving arrangements can extend exposure.
Can I use 2 lb per cubic foot for every box?
No. Establish quantity and layout using evidence for the actual configuration.
What if the receiver is unavailable?
Apply the agreed exception plan and assess the revised exposure. A completed delivery scan alone is not suitable product storage.
Keep the worksheet with the shipment
Retain the loading and timing record alongside the accepted packing instruction. This article covers next-day execution; use three-day route planning when the intended exposure is longer.
