How to Ship Fresh Produce: Temperature Bands, Airflow, and Direct Refrigerated Freight
Guide to shipping fresh fruits and vegetables on pallets. Covers commodity temperature bands, ventilated packaging and airflow, ethylene compatibility, refrigerated box trucks and 53-foot trailers, and produce receiving.
Quick reference
Recommended packaging
Use vented produce cartons or RPCs sized to the commodity and stack them in aligned columns so vent holes line up and air moves vertically through the pallet. Do not wrap airtight — use vented stretch wrap, corner boards with strapping, or pallet netting so the cold chain can actually reach the product. Pre-cool to the commodity's carry temperature before tender. Keep ethylene producers (apples, bananas, stone fruit) away from ethylene-sensitive loads (leafy greens, broccoli, cucumbers) unless the whole load carries compatibly.
Accessorials you may need
These are the most common accessorial services for fresh produce shipments. Declare them at booking time — carriers that discover them on arrival bill more and back-date to the invoice. With Warp, every accessorial below is already included in the per-pallet rate.

Shipping tips for fresh produce
- Pre-cool before pickup. Field heat is the enemy — refrigerated equipment holds temperature, it does not remove the heat a warm harvest carries.
- Align vent holes when stacking cartons. A pallet with blocked vents insulates its own core and the middle boxes arrive warm no matter what the unit reads.
- Match the setpoint to the most sensitive commodity on the load, and check ethylene compatibility before mixing produce on one truck.
- Count transit in hours, not days. Direct dispatch matters more for produce than for any dry freight — every transfer is shelf life spent.
Common mistakes to avoid
Mistake 1: Standard LTL trailers are not temperature-controlled. Fresh produce moves on refrigerated equipment — for pallet quantities that means a refrigerated box truck, not a dry LTL network.
Mistake 2: Airtight shrink-wrap suffocates produce and blocks the cold chain. Vented wrap or netting only.
Mistake 3: Produce receivers document pulp temperature at the dock and refuse loads outside the band. A warm tender at origin cannot be fixed in transit, and the paperwork will show where the temperature was lost.
Temperature bands are per commodity, not one number
Fresh produce does not share one carry temperature. Leafy greens, berries, and broccoli ride just above freezing at 32 to 36 F. Citrus and most stone fruit carry in the 38 to 48 F range. Chill-sensitive commodities — tomatoes, cucumbers, peppers, bananas — are damaged below roughly 50 F and carry at 50 to 55 F. The rule for a mixed load is to set the unit for the most sensitive commodity on board and to check ethylene compatibility: apples, bananas, and stone fruit give off ethylene that yellows greens and over-ripens whatever rides beside them. When a load cannot carry compatibly, split it. Put the setpoint on the BOL so the driver, the unit, and the receiver are all working from the same number.
Packaging for airflow, not against it
Refrigerated equipment cools by moving air, and produce packaging has to let that air through. Vented cartons stacked so the vent holes align create vertical channels through the pallet; blocked vents turn the center of a pallet into an insulated warm core that no setpoint can fix. Skip airtight film — vented stretch wrap, pallet netting, or corner boards with strapping hold the load square without sealing it. Pre-cooling does the heavy lifting: product should enter the truck at its carry temperature, because a refrigeration unit maintains temperature and airflow, it is not a cooler that pulls field heat out of a warm harvest.
How Warp runs fresh: direct, refrigerated, hours not days
Produce pays for every extra touch. Warp moves fresh product on refrigerated box trucks for pallet-scale shipments — 1 to 12 pallets, farm, port, or warehouse pickup, dispatched direct to the receiver with liftgate available and per-pallet pricing with no reefer surcharge — and on refrigerated 53-foot trailers for full loads. Direct dispatch means no terminal transfers and no ambient dock time, which is where produce loses both temperature and shelf life. Receiving is its own discipline: produce DCs and wholesale markets run early-morning windows, enforce appointments, and pulp-check at the dock. Book the appointment with the freight, and if your receiver is a market stall or a site without a dock, flag the liftgate and access situation up front.

Fresh Produce shipping FAQ
Can fresh produce ship on standard LTL freight?
No. Standard LTL trailers are not temperature-controlled, and the terminal network adds ambient dock time a fresh commodity cannot absorb. Pallet quantities of produce ship on a refrigerated box truck moving direct; full loads ship on a refrigerated 53-foot trailer. Warp runs both.
What temperature does produce ship at?
It depends on the commodity: 32 to 36 F for greens and berries, 38 to 48 F for citrus and most stone fruit, and 50 to 55 F for chill-sensitive items like tomatoes, cucumbers, and bananas. A mixed load sets the unit for its most sensitive commodity — and checks ethylene compatibility before mixing.
What freight class is fresh produce?
Produce spans roughly class 50 to 92.5 depending on commodity density and packaging — dense cased root vegetables sit low, light leafy commodities in tall vented cartons sit higher. Fresh fruits and vegetables are classed under commodity-specific NMFC items, so confirm the exact item for your product before booking.
Why is my produce arriving warm in the middle of the pallet?
Blocked airflow. If vent holes are misaligned or the pallet is wrapped airtight, the core of the pallet insulates itself and the unit only cools the outer cases. Stack cartons so vents align into vertical channels, use vented wrap or netting, and pre-cool before tender so the equipment is holding temperature rather than chasing it.
How is refrigerated produce freight priced?
Pallet-scale fresh shipments on Warp price per pallet on a refrigerated box truck with no reefer surcharge; full loads price as a refrigerated 53-foot trailer. Get a quote with your lane and pallet count, or book a strategy call if you move fresh volume on a weekly schedule.
