At our brokerage, Fall River Express, we work with shippers across food and beverage, manufacturing, pharmaceuticals, and more. In this post, we're answering frequently asked questions about reefer freight, and sharing what, in our experience, separates great temperature-controlled carriers from less capable ones.
Temperature-controlled shipping (also called reefer freight or cold chain shipping) is the transportation of cargo that must be maintained at a specific temperature from the point of origin to the final destination. That includes the time it spends in storage, loaded on a truck, or sitting at a dock.
It's broader than most people think. "Temperature-controlled" doesn't just mean refrigerated. Depending on the product, it might mean:
Reefer trailers can operate across a wide range—from as warm as 80°F down to as cold as -20°F—but not all trailers are built the same. Products like ice cream, for example, require trailers with thicker insulated walls to hold extreme cold reliably. Matching your product to the right equipment matters.
Some of the most common temperature-sensitive shipments include:
Wisconsin's economy is built around many of these products. Our state is one of the country's leading producers of dairy and food products, which means temperature-controlled logistics isn't a niche service here—it's a daily necessity for hundreds of shippers across the region.
In our brokerage, this is one of the first things we cover with any new reefer customer. Before we can find the right equipment and the right carrier, we need to know:
The more precisely you can answer these questions upfront, the smoother the process. Vague temperature requirements or incomplete product descriptions are one of the most common sources of avoidable problems in cold chain shipping.
It requires more attention, yes. With dry van freight, the risk is largely physical; for example, did something break or get damaged in transit? With reefer freight, the risk is invisible until it's too late. If a carrier isn't running the reefer unit correctly, your product can be damaged without a single physical impact.
And modern reefer units are fully computerized, so they log the temperature throughout the entire haul. There's a complete audit trail. We call it "tattletale freight": the data tells the story of exactly what happened, every mile of the route. This is why experienced reefer drivers operating well-maintained equipment is essential.
Wisconsin presents some real cold chain challenges that shippers in milder climates don't have to think about as often. In summer, certain products need active cooling from the moment the load leaves your dock. In winter, the concern flips: some products that don't normally need refrigeration (like bottled water) actually need a heated trailer to prevent freezing. Understanding which direction the temperature threat is coming from, depending on the time of year, is part of good planning.
The single most important thing you can do before booking a reefer shipment is knowing your product's specific required temperature range. Share it in writing with your carrier every time. The temperature requirement drives equipment selection, carrier selection, and determines what qualifies as a successful delivery. Without it, nothing else can be planned correctly.
Not all reefer trailers are built the same. Ice cream and other deep-frozen products require trailers with thick insulated walls to maintain extreme cold reliably. Trying to cut costs by using a standard reefer trailer for a product that requires heavy insulation is a risk not worth taking. The cost of a ruined load far exceeds any savings on equipment.
Reefer trailers can't scale as much weight as dry van. Plan your loads with that in mind, and communicate your pallet count and weight accurately when booking. Surprises at the scale create delays and, sometimes, compliance issues.
Due to the delicate nature of reefer freight, you want to be sure you're working with an experienced, skilled, and reliable carrier. For example, at our brokerage, we control for this by requiring partner carriers to have a minimum of one year of operating history, verifying that they have a good safety score, checking their insurance coverage satisfies the requirements, and monitoring their performance while they are are driving a load. We only work with carriers who meet our standards—and we'd encourage any shipper to ask those same questions of any carrier they work with.
Modern reefer units are computerized and log temperature data throughout a shipment. Your carrier should be able to provide that documentation. For example, we use McLeod TMS integrated with Samsara for real-time in-cab communication and tracking.
If your product is going to a grocery distribution center or similar facility, your delivery appointment may be in the middle of the night. That's standard in the reefer world, so experienced reefer carriers are used to it. But it affects driver hours and transit planning, so make sure your carrier knows the appointment details well in advance.

Temperature-controlled shipping is one of the highest-stakes areas of freight logistics. The margin for error is small, the consequences of failure are significant, and the regulatory environment is demanding. For Wisconsin shippers—whose businesses are often built on the dairy, food, and pharmaceutical industries that depend on reliable cold chains—choosing the right partner isn't a detail. It's a foundation.
Since 1993, Badger Logistics has been that partner for 500+ shippers across Wisconsin and North America. We're not just a broker with a carrier list. We're an integrated logistics provider with our own assets, our own food-grade warehouse, and a team that answers the phone and solves problems—not one that tells you no.
