Why do some couriers decline refrigerated freight?
Quick answer
Because refrigerated freight needs a reefer — a truck with a powered refrigeration unit, an insulated box and temperature monitoring — and most couriers run dry vans and box trucks. Hauling temperature-sensitive product in a dry vehicle risks spoilage the carrier can't defend, so honest carriers decline the load rather than improvise. Sonic Transport doesn't offer temperature-controlled service; that freight belongs with a specialized reefer carrier.
If a courier has turned down your chilled or frozen shipment, it wasn’t arbitrary — and it wasn’t about the size of the job. Refrigerated freight is a specialized trade, and a carrier that runs dry vehicles has no honest way to take it. Understanding why makes it much easier to place that freight with the right carrier the first time.
Refrigeration is a different machine, not an add-on
A refrigerated carrier runs fundamentally different equipment: an insulated cargo box, a powered refrigeration unit that holds a setpoint, and monitoring of conditions through the trip. That combination — the reefer — is what “temperature-controlled” actually means. It isn’t a feature you switch on in an ordinary truck; it’s a different vehicle, bought, maintained and operated for that purpose.
A standard cargo van or 26-foot box truck is an uninsulated, unpowered box. In a Southern Ontario summer, the inside of a dry cargo box gets significantly hotter than the air outside; in winter it can sit below freezing for the whole run. Nothing about a dry vehicle holds a temperature — which is the entire requirement of the freight.
“It’s only a short run” doesn’t change the answer
The most common push-back is distance: surely thirty minutes across town can’t matter. But temperature-sensitive product isn’t specified as “cold when it left and probably fine” — it’s specified as held within a range, continuously. A dry truck offers no control and no evidence, so even a short trip is an undocumented excursion. The receiver has no way to verify the product’s condition, and many receivers of chilled goods check arrival temperature and refuse product that’s out of range. A short run in the wrong equipment doesn’t shrink the problem; it just shortens the time before it’s discovered.
The liability problem behind the refusal
When a carrier accepts freight, it accepts responsibility for delivering it in good condition — and a dry-freight courier cannot stand behind the condition of temperature-sensitive product. If the product spoils, the claim lands on a carrier that had no ability to prevent it and no data to defend itself with. Carriers are also expected, by shippers and insurers alike, to match equipment to freight; knowingly running chilled product in a dry box is the kind of corner-cutting that turns one shipment into a lasting dispute.
So the refusal is really a statement of honesty: the carrier is telling you it can’t protect your product, before your product pays the price. It’s the same category of straight answer covered in what a regular courier can’t carry — every serious carrier has that list, and the good ones volunteer it.
What dry-freight couriers move instead
Everything else, roughly. Ambient commercial freight is the overwhelming majority of B2B shipping: parts and components, finished goods, equipment, tools, fixtures, packaging, materials, documents and devices. For that freight, an enclosed dry vehicle is exactly the right protection — weather-tight, secure and matched to the load. Our answer on whether freight rides enclosed and secure covers what that protection looks like in practice.
That’s the trade Sonic Transport is in: dry B2B freight across the GTA, Golden Horseshoe and Southern Ontario, from single cartons to multi-skid loads, on same-day direct runs and scheduled work. We don’t offer temperature-controlled service, and we say so up front rather than after your product is on a truck.
How to tell if your freight is genuinely temperature-sensitive
The test is the product’s specification, not the season. If the manufacturer or your customer specifies a storage or transport temperature range, treat the load as temperature-controlled freight and place it with a reefer carrier — “keep refrigerated” on a label is the end of the conversation. Freight that merely prefers moderation — goods that shouldn’t sit in the sun for a day but carry no specified range — is ordinary ambient freight, and an enclosed dry vehicle on a direct run protects it the way it protects everything else.
When the spec is ambiguous, ask whoever owns it: the manufacturer, or for regulated products, the relevant regulator. What you shouldn’t do is quietly downgrade chilled product to “probably fine” so it fits the truck that’s available — that call belongs to the owner of the product specification, not to the freight booking.
How to place freight that genuinely needs temperature control
Look for a carrier that advertises refrigerated or temperature-controlled service specifically — it’s a distinct capability, not a general-courier upgrade. When you talk to them, be ready with the details that trade runs on: the required temperature range, whether the product is chilled or frozen, monitoring or documentation you need, and loading conditions at each end. If your product is in a regulated category, confirm current handling requirements with the relevant regulator rather than relying on the carrier alone.
And if the run is a mixed one — some freight chilled, some ambient — split it. Sending the dry portion with a dry-freight courier and the chilled portion with a reefer carrier costs less than forcing either carrier out of its lane. If freight terminology is part of the confusion, the freight terms glossary sorts reefer, ambient, dry van and the rest.

Tell us what’s shipping and we’ll quote the freight we’re built for, and tell you honestly when a load belongs with a specialist.

What exactly is a reefer?
A reefer is a refrigerated truck or trailer: an insulated cargo box with a powered refrigeration unit that holds a set temperature, typically with monitoring or recording of conditions in transit. It's purpose-built equipment operated by carriers who specialize in temperature-controlled freight.
Couldn't the courier just use ice packs or insulated blankets?
Improvised cooling isn't temperature control — it can't hold a setpoint, can't be verified, and gives the receiver no basis to accept the product's condition. Carriers that handle temperature-sensitive freight properly do it with powered, monitored equipment, which is exactly why dry-freight couriers decline instead of improvising.
Does declining refrigerated freight mean a courier is less capable?
No — it means the carrier is honest about its equipment. Dry freight and reefer freight are different trades with different vehicles and operating disciplines. A courier that says no to a chilled load and yes to the dry freight it's built for is behaving exactly the way you want a carrier to behave.
