Blueberry cold chain: temperature, shelf life and transport choices
Fresh blueberries keep best at −0.5 to 0 °C with 90–95% relative humidity, and UC Davis gives an approximate storage life of 10–18 days under those conditions. That window has to cover packing, transport and retail, so long sea routes need fast forced-air cooling, a stable reefer set point and minimal handling, while air and road routes trade speed against uncontrolled ground time. ColdMatch helps packhouses and importers specify cooling, storage and monitoring infrastructure; it does not transport fruit.

ColdMatch Group is a sourcing and procurement platform for refrigeration and cold-chain infrastructure. It is not a carrier, freight forwarder, packhouse or inspection body, and it does not quote freight or guarantee shelf life. This page is planning information, not food-safety or legal advice.
Sea, air or road for blueberries
No freight rates are given. Transit depends on carrier, service and season; confirm schedules with your forwarder.
| Option | Typical use | Strengths | Watch-outs |
|---|---|---|---|
| Reefer container (sea) | Long routes, for example Peru to the US, Europe or Asia | Volume and stable set point when the chain is unbroken | Voyage uses much of the 10–18-day storage life; needs fast cooling and careful set point |
| Airfreight | Early-season, premium or distant markets | Short transit preserves remaining shelf life | Warm ground time at airports; condensation when pallets move between temperatures |
| Refrigerated truck (road and ferry) | Shorter routes, for example Morocco to the UK and EU | Door-to-door control with fewer transfers | Border and ferry waits; trailer unit reliability |
UC Davis storage table: −0.5 to 0 °C, 90–95% RH, highest freezing point about −1.3 °C, approximate storage life 10–18 days, 2–5% O₂ + 12–20% CO₂ listed as beneficial atmosphere.
Corridor decision matrix
One row per verified corridor. Use it to decide what to confirm with your exporter, forwarder, postharvest or food-safety adviser and the competent authorities before you commit. Seasons and evidence carry their own label.
Peru → United States, Netherlands/EU, China
- Season
- Exports start in July, peak in October and decline gradually from November to March (MIDAGRI seasonality study). Official source
- Transport mode
- Reefer container; airfreight for part of early-season volume
- Temperature / specification to confirm
- −0.5 to 0 °C and 90–95% RH; highest freezing point about −1.3 °C; approximate storage life 10–18 days (UC Davis storage table).
- Packaging
- Vented clamshells in cartons; vents aligned through the pallet for forced-air cooling.
- Transit risk
- Voyage uses much of the storage life; condensation when cold pallets meet warm air; softening and decay.
- Handoff questions
- How soon after picking does forced-air cooling start, and to what pulp temperature?
- What minimum remaining shelf life is agreed at arrival?
- Who handles cold transfer at the destination port or airport?
Morocco → United Kingdom, Spain, Netherlands
- Season
- Export window December to June, peaking in April (International Blueberry Organization). Trade association
- Transport mode
- Refrigerated truck via ferry; reefer container
- Temperature / specification to confirm
- −0.5 to 0 °C and 90–95% RH (UC Davis storage table); trailer set point stated in the transport contract.
- Packaging
- Vented clamshells and cartons; pallets secured for road and ferry movement.
- Transit risk
- Port and ferry waits; trailer unit reliability; condensation at cross-docking.
- Handoff questions
- Is the trailer plugged in during the ferry crossing and port waits?
- Which logger file travels with the load?
- Where does cross-docking happen, and is that dock temperature-controlled?
Practical planning guidance only — not legal, food-safety or phytosanitary advice, and not a shelf-life promise. Temperatures are reference values from the cited standards and studies; the binding values come from your contract, your specialist and the importing authority. ColdMatch does not transport, store or inspect cargo and gives no cost figures here.
Forced-air cooling and packaging
Blueberries are forced-air cooled in vented clamshells and cartons and should not be wetted. Vent holes must line up through the pallet, and cooling should start soon after harvest.
- Size forced-air tunnels for the peak picking day.
- Keep pallets intact and corner-boarded so vents stay open.
- Record pulp temperature at the end of cooling and at loading.
Condensation and the cold chain break
When cold pallets are opened or moved into warm, humid air, water condenses on the fruit and packaging, which encourages decay. Plan cold docks, short transfers and gradual temperature changes, especially at airports.
Main corridors (dated evidence)
Peru exported 373,514 tonnes of fresh blueberries in 2025, according to MIDAGRI, which describes Peru as the leading fresh-blueberry exporter; preliminary shares put the United States at 50% and the Netherlands at 23% of volume. Morocco shipped about 19,000 tonnes to the UK between July 2024 and June 2025, roughly 25% of UK blueberry imports (International Blueberry Organization, EastFruit analysis; not confirmed against Moroccan official data).
Shelf-life risk and claims
Common problems are softening, shrivel and decay. Agree minimum remaining shelf life and arrival inspection criteria in the sales contract. Keep pulp readings, logger files, photos and survey reports. Notice periods depend on mode and contract: three days for non-apparent damage under the Hague-Visby Rules (sea), 14 days from receipt under the Montreal Convention (air) and seven days, excluding Sundays and public holidays, under the CMR (road). Take legal advice for a specific claim.
Where ColdMatch fits
ColdMatch is free for buyers. Its team reviews forced-air cooling, cold-storage and monitoring requests of USD 250,000 and above, contacts suitable suppliers on the buyer's behalf and presents organised responses. There is no direct buyer-to-supplier contact.

How to request comparable quotes
- Complete the checklist and state the number of forced-air tunnels you need.
- Separate cooling duty, holding rooms and dock equipment in the scope.
- Ask suppliers for humidity control and monitoring details and documented energy data only.
- Submit the RFQ. Requests of USD 250,000 and above are reviewed by the ColdMatch team before any supplier is contacted.

Frequently asked questions
What is the best temperature for fresh blueberries?
The UC Davis storage table gives −0.5 to 0 °C with 90–95% relative humidity; the highest freezing point is about −1.3 °C, so set points should stay above it.
How long do blueberries last in cold storage?
UC Davis gives an approximate storage life of 10–18 days at recommended conditions. Actual life depends on variety, harvest condition and how well the cold chain is kept.
Does ColdMatch ship blueberries?
No. ColdMatch does not ship, store or inspect fruit. It helps buyers procure cooling, storage and monitoring infrastructure.
Why do berries decay after airfreight?
Often because of warm ground time and condensation when cold pallets move into humid air. Cold handling at both airports and short transfers reduce this risk.
