Avocado import cold chain: temperature, atmosphere and ripening on arrival

Holding conditions by fruit stage

Two UC Davis references give different ranges; the right set point depends on cultivar, maturity and how long the fruit will be held.

Relative humidity of 90–95% is given for avocados in the UC Davis fact sheet. Confirm settings for your cultivar and route with a postharvest specialist.

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.

• Mexico → United States

  Season

  Exports run year-round, with a peak from December to February (USDA FAS Avocado Annual). Official source

  Transport mode

  Refrigerated truck across the land border

  Temperature / specification to confirm

  Mature-green fruit 5–13 °C depending on cultivar and duration, 90–95% RH (UC Davis); confirm the set point with your specialist.

  Packaging

  Cartons on stable pallets; no mixing with ethylene-sensitive products.

  Transit risk

  Border dwell in warm weather; chilling injury if held too cold; early softening if too warm.

  Handoff questions

  • Are orchards and packhouses enrolled in the APHIS-approved programme for this shipment?
  • What trailer set point and logger interval apply from packhouse to receiver?
  • Where and how long will the truck wait at the border?

  Evidence: [11], [12], [9]

• Peru → Europe, United States, Asia

  Season

  The coastal Hass campaign runs roughly May to September (press report; confirm with exporters). Press report

  Transport mode

  Reefer container, often with controlled atmosphere

  Temperature / specification to confirm

  Mature-green holding band and controlled-atmosphere settings agreed per cultivar and voyage length (UC Davis gives 5–13 °C; storage table 3–7 °C for Hass).

  Packaging

  Cartons and pallets compatible with controlled-atmosphere containers.

  Transit risk

  Multi-week voyages; uneven ripening at destination; chilling injury visible only after ripening.

  Handoff questions

  • Which oxygen and carbon dioxide settings will the container hold?
  • Does the fruit arrive green or pre-conditioned, and who sets the ripening programme?
  • Which arrival records will prove the set point was kept?

  Evidence: [13], [14], [9], [10]

Practical planning guidance only — not legal, food-safety or phytosanitary advice, and not a shelf-life promise.

ColdMatch does not transport, store or inspect cargo and gives no cost figures here.

Two import patterns: land border and long sea voyage

Mexico supplied 89% of US avocado import volume and 92% of value in 2021, according to USDA APHIS, mostly by refrigerated truck. Hass avocados enter the US from approved Mexican states under an APHIS systems approach; the 2016 rule extended entry to all US states. Peru exported 769,774 tonnes of avocados in 2025 (PROMPERÚ, SUNAT data), mainly by reefer container over voyages of several weeks, where controlled atmosphere and steady temperature matter more.

Ethylene and mixed loads

Avocados produce and respond to ethylene. Do not mix them with ethylene-sensitive products in the same room or container, and keep ripening rooms separate from holding rooms.

• Agree whether fruit arrives pre-conditioned or fully green.
• Plan ripening capacity for the arrival programme, not average weekly volume.
• Monitor CO₂ in ripening rooms and ventilate as your specialist specifies.

Receipt, inspection and port dwell

Check pulp temperature, firmness and logger records on arrival, and move fruit into a cold room quickly. Long dwell at a port or border crossing in warm weather starts ripening early and shortens the sales window.

Shelf-life risk and claims

Common disputes involve chilling injury (internal browning that may appear only after ripening), uneven ripening and decay. Keep pulp readings, logger files, ripening-room records and photos. Notice periods depend on the transport convention and contract: three days for non-apparent damage under the Hague-Visby Rules (sea) 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 cold-storage, controlled-atmosphere and ripening-room 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.

RFQ checklist for avocado import facilities

State each item for the receiving, storage or ripening facility you are procuring. Values come from you or your postharvest adviser.

• CommodityCultivar (for example Hass), maturity at arrival, size counts.
• OriginSupplying countries and how fruit arrives (truck, reefer, controlled atmosphere).
• DestinationFacility location and the markets or retailers it serves.
• VolumePallets per week at peak, ripening-room batches, storage days.
• TimingArrival programme by month and target commissioning date.
• PackagingCarton type and pallet pattern used by your suppliers.
• Temperature and specHolding and ripening temperatures, ethylene and CO₂ control, RH, as set by your specialist.
• DocumentsImport permits, phytosanitary certificates, logger and ripening-room records.

How to request comparable quotes

1. Complete the checklist and state the number and size of ripening rooms.
2. Separate holding rooms, ripening rooms and dock equipment in the scope.
3. Ask suppliers for ethylene, CO₂ and humidity control details and documented energy data only.
4. Submit the RFQ. Requests of USD 250,000 and above are reviewed by the ColdMatch team before any supplier is contacted.

Glossary

Mature-green

Fruit that has reached harvest maturity but has not started to soften.

Chilling injury

Damage to cold-sensitive fruit held below its safe temperature, often visible only after ripening.

Ethylene

A natural plant hormone that triggers ripening; avocados produce it and respond to it.

Controlled atmosphere (CA)

Storage or transport with regulated oxygen and carbon dioxide levels to slow ripening.

Pre-conditioning

Partial ripening before dispatch so fruit ripens faster at destination.

Systems approach

A set of combined phytosanitary measures from orchard to export that allows market access.
