Glace sèche has no universal 24–72-hour lifetime. For dispatch planning, count time from supplier receipt and measure the usable material actually available when packing. Buying enough for a shipment on paper does not establish that the same amount remains after storage, preparation queues or a missed pickup.
Define the period you are planning
Separate supplier delivery, site storage, material allocation, packing and carrier pickup. Record the expected times and what happens if an event is delayed. Dry ice continues to sublimate rather than waiting for the parcel label to be printed.
The amount remaining before packing and the product’s useful shipping duration are different questions. Plan both, with observations relevant to the actual operation.
Keep quantities linked to their stage
| Scène | Quantity question |
|---|---|
| Supplier receipt | What actual material and mass arrived? |
| Stockage | What elapsed exposure occurs before allocation? |
| Emballage | How much supported loading is required for this configuration? |
| Dispatch wait | Does a later pickup change the represented exposure? |
| Trial or receipt | What residual observation and temperature evidence exist? |
Do not substitute an invoice amount for the quantity allocated to the actual package. Avoid a universal daily loss rule that ignores container, formulaire, exposure and handling.
Plan a delayed pickup without guessing
- Identify orders and material affected by the delay.
- Retain the actual packing and preparation times.
- Check the product’s required control conditions.
- Assess the remaining usable stock through the defined method.
- Review the revised exposure against supporting evidence.
- Obtain the responsible decision before release.
Do not automatically top up a completed parcel or copy the original transport quantity without reviewing the actual configuration and applicable instructions. An intervention can change loading and records.
Use suitable storage and handling
Follow the dry-ice supplier and site instructions for compatible storage, handling and surrounding ventilation. Do not seal the material to stop loss or assume an ordinary freezer recharges sublimated CO₂.

Questions fréquemment posées
Does the shipping clock begin only at pickup?
The relevant product exposure can begin earlier. Record packing and preparation timing.
Can I assume the purchased mass is still available tomorrow?
Non. Establish actual usable stock under the site procedure.
Does leftover dry ice prove shipping duration?
Non. Product-temperature acceptance requires its own evidence.
Keep mass and temperature evidence separate
Utiliser the sublimation measurement guide for coolant observations and the temperature-report interpretation guide for product acceptance.
