5 Things Food Shippers Must Do in the Next 30 Days as Reefer Capacity Tightens

Reefer rates are spiking. Produce season is in full swing. And the shippers who are still waiting on the spot market to bail them out are about to find out what that strategy really costs.

This isn't a slow-moving trend. Refrigerated freight capacity tightens fast during peak produce months, and when it goes, it goes. Rates that looked manageable in April can jump 20 to 30 percent by late June on high-demand lanes out of growing regions like the San Joaquin Valley, Nogales, and the Carolinas. Trucks that were available last week get absorbed quickly, and brokers who don't have carrier relationships in place are left scrambling.

If you manage cold chain shipping, produce logistics, or any temperature-controlled freight program, here are five things you need to do in the next 30 days.

1. Lock In Contract Rates on Your Highest-Volume Lanes Before Spot Premiums Eat Your Margin

Spot rates on reefer freight don't creep up slowly. They spike when demand clusters, and during produce season that happens fast. A lane that runs $2.80 per mile on contract can hit $3.50 or higher on the spot market during a compressed shipping week.

Look at your freight data from the last 90 days. Find the lanes where you're moving the most volume, the ones you know are going to run all summer. Those are the lanes to lock down first. Contract rates aren't always perfect, but they give you price predictability and they give carriers a reason to prioritize your freight when things get tight.

If you're working with a freight broker, have that conversation this week. Not next week. The carriers who are willing to hold rates are making commitments now, not in July when everyone is calling at the same time.

2. Audit Your Carrier List and Cut the Dead Weight

Most shipping programs carry carriers on their approved list who haven't moved a load in six months. That list means nothing when capacity is tight. What matters is who picks up the phone, who sends a driver, and who has the reefer equipment to actually protect your product.

Go through your active carrier pool and ask a few direct questions. Which carriers ran on time last peak season? Which ones had temperature excursions or load refusals? Which ones have you actually been able to reach when something went sideways?

Tight capacity exposes weak carrier relationships fast. A carrier who barely covers your lanes in a loose market is not going to be there for you when every other shipper is calling them too. This is the time to build tighter relationships with fewer, more reliable carriers rather than having a long list that doesn't perform.

For food shippers specifically, this also means confirming that your carriers are running food-grade equipment that's clean, pre-cooled properly, and compliant with FSMA carrier requirements. A cheap rate on a dirty trailer isn't a deal.

3. Build Backup Coverage Into Your Freight Program Before You Need It

Your primary carrier going down during peak season is not a hypothetical. It happens every year. A truck breaks down in Fresno. A driver calls out. A carrier over-commits and can't cover. If you don't have a backup plan locked in before that happens, you're making panicked calls with a load sitting on a dock and no leverage at all.

Good backup coverage means having at least one or two secondary carriers pre-qualified on your top lanes, or having a freight broker relationship where you know they can move fast. It also means understanding your own facility's constraints, knowing how much dock time you have before a perishable load becomes a problem.

A produce shipper moving strawberries out of Florida to the Northeast has a window that is measured in hours, not days. When a truck falls through at 4pm on a Friday, the difference between a working backup plan and no plan can be a full load of product going to waste.

4. Tighten Your Pickup Windows and Make Your Freight Easier to Move

This one is straightforward but most shippers ignore it. When capacity is tight, carriers and brokers prioritize freight that is easy to dispatch. That means clear pickup windows, accurate load times, docks that are ready when the driver shows up, and paperwork that doesn't create delays.

If your standard pickup window is 8am to 5pm with no appointment, you're competing with every other load on the board. If you can offer a tighter, more predictable window, say 10am to 1pm with a confirmed appointment, you become a more attractive load for a driver planning their day.

Flexible shippers get capacity when rigid ones don't. That's not a theory. Carriers talk to each other, and they remember which shippers run clean operations. Small operational improvements on your end translate directly into better coverage during crunch time.

5. Talk to Your Freight Broker Now, Not When You Have a Load on the Dock

The worst time to call your broker is when you're already in a crisis. A load is sitting, the clock is running, and you need a truck in two hours. At that point, whoever you're calling is working from a position of weakness and so are you.

The best time to call is right now, before peak is fully underway, when there's still room to plan. A good freight broker who specializes in cold chain and food logistics can help you map your exposure, identify which lanes are most vulnerable to spot rate spikes, and put carrier coverage in place before it's an emergency.

At SFL, we work with food shippers, produce shippers, and cold chain programs across the country. We know which lanes are tightening and we know how to build coverage that holds when the market gets ugly. We are not here to take your spot loads when you're desperate. We'd rather help you set up a program that keeps you out of that situation in the first place.

The Shippers Who Move This Week Are in a Different Position Than the Ones Who Wait

Produce season doesn't slow down to let you catch up. The capacity that's available today is tighter than what was available in April, and it's going to get tighter before it gets easier. The shippers who are making calls, locking in rates, and building backup coverage right now are going to have a very different summer than the ones who wait until they're scrambling.

If you're moving refrigerated freight and you want to talk through where your program is exposed, reach out to SFL. We'll give you a straight answer on what we're seeing in the market and what it means for your lanes.
