Reefer breakdown coverage: when a failed unit spoils the load

A refrigerated load can be ruined without any accident. The unit stops cooling, the product warms, and the receiver rejects it. Nothing crashed, nothing burned, nobody stole anything.

Many motor truck cargo forms exclude or limit loss caused by temperature change, spoilage, or mechanical breakdown of refrigeration equipment unless an endorsement adds it back. That endorsement is what the industry calls reefer breakdown. Brokers hauling food and other perishables commonly ask carriers to show it on the certificate. See reefer trucking insurance and motor truck cargo insurance.

Reefer breakdown covers the freight. It does not pay to repair or replace the reefer unit itself. Under the ISO motor carrier physical damage wording, loss "due and confined to" wear and tear or mechanical or electrical breakdown is excluded. A reefer unit that simply fails is a maintenance cost unless your policy or an equipment breakdown endorsement says otherwise.

There is no standard ISO reefer breakdown form. Each cargo insurer writes its own, and the wording decides the claim. These are the provisions to read.

Definition of breakdown. Many endorsements require a sudden and accidental mechanical or electrical failure of the unit. Some cover only failure of the unit itself, not of a door seal, a power cord at a shipper's plug-in, or the trailer's insulation.

Minimum duration. Some endorsements cover spoilage only if the unit was inoperative for a minimum number of hours. A short failure that still ruins a sensitive load may not qualify.

Operator error and settings. Wrong setpoints, continuous vs start-stop mode, running out of fuel, or failing to pre-cool are common reasons claims are denied. Some endorsements exclude these; some cover them for a higher deductible.

Maintenance records. Some endorsements require that the unit was maintained on a schedule, and the insurer may ask for service records and the unit's download.

Deductible. Reefer breakdown often carries its own deductible, separate from the cargo deductible.

Rejected loads. A receiver can reject a load for a temperature excursion even when the product is not actually spoiled. Whether the policy pays for a rejected load, salvage, or disposal, and how it handles the difference between rejection and damage, varies by form.

For food, the FDA's sanitary transportation rule (21 CFR part 1, subpart O) assigns duties based on what shippers and carriers agree to in writing. Where a carrier takes on responsibility for sanitary conditions, 21 CFR 1.908(e) requires it to:

• make sure its vehicles and equipment meet the shipper's specifications;
• pre-cool each mechanically refrigerated cold storage compartment as the shipper specifies before offering the vehicle for loading;
• on request, give the receiver the shipper's specified operating temperature; and
• on request, demonstrate that it maintained temperature conditions during the trip, by any appropriate means agreeable to the carrier and shipper.

The carrier must also have written procedures for cleaning, sanitizing if necessary, inspecting equipment, and meeting the temperature control provisions.

These are regulatory duties, not insurance terms. But they create the same records an insurer will ask for after a spoilage claim: the setpoint the shipper gave you, proof of pre-cooling, and a temperature download for the trip. A carrier that can produce them is in a far better position on a claim, with the shipper, and with the broker. Have an attorney advise on your FDA obligations.

Reefer losses do not always happen on the road. A loaded reefer trailer sitting at a yard or a customer's dock can fail too, and the question becomes which policy, if any, responds.

A 2022 Fifth Circuit decision applying Texas law shows how this goes wrong. A San Antonio food company stored product in a reefer trailer parked at its own premises because its warehouse was full. The unit failed and the product spoiled. Its equipment breakdown policy excluded equipment "mounted on or used solely with any vehicle," and the court held that a reefer trailer is a vehicle even when it is detached from a tractor, so there was no coverage under that policy. (The opinion is unpublished and the claim under a separate cargo policy was not before the court.)

For a carrier, the lesson is to ask your cargo insurer directly how long loaded trailers are covered while parked at your yard, at a drop lot or at a customer's dock, and whether reefer breakdown applies while the trailer is not in transit. See the unattended vehicle exclusion for a related condition.
