How to Ship Frozen Food: Refrigerated Box Trucks and Refrigerated 53s
Guide to shipping frozen food on pallets. Covers why standard LTL cannot carry frozen product, how refrigerated box trucks and refrigerated 53-foot trailers work, pre-freezing, insulated packaging, and cold-storage receiving.
Quick reference
Recommended packaging
Freeze product solid to its holding temperature before tender — transport equipment maintains temperature, it does not pull warm product down. Stack sealed cases in an interlocking brick pattern on a standard GMA pallet, keep the footprint square with no overhang, and wrap with five or more layers of stretch film. For dock time and staging, add an insulated pallet cover or foil-faced blanket. Mark the pallet "Keep Frozen" on all four sides and note the required temperature on the BOL.
Accessorials you may need
These are the most common accessorial services for frozen food 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 frozen food
- Pre-freeze for 24 to 48 hours before pickup. A pallet tendered at minus 10 F rides out dock transfers; a pallet tendered at 20 F arrives soft and gets rejected.
- Book the tightest transit you can. Frozen product survives on time, not on equipment alone — direct dispatch with no terminal stops means less door-open time.
- Confirm the receiver is a cold-storage dock with an appointment. Frozen deliveries without an appointment wait, and waiting is warming.
- Note the setpoint on the BOL (0 F or below for most frozen food). The driver runs the unit to what the paperwork says.
Common mistakes to avoid
Mistake 1: Standard LTL trailers are not temperature-controlled and never suitable for frozen food, in any season. Frozen product must move on refrigerated equipment end to end.
Mistake 2: Receivers temperature-check at the dock. Product that reads above its holding temperature gets refused, and carriers deny claims when the product was tendered warm — record the pulp temperature at pickup.
Mistake 3: Frozen cases are dense. Two pallets of frozen protein can exceed 4,000 lbs — confirm pallet weights and liftgate capacity before booking.
Why frozen food never rides standard LTL
A standard LTL trailer is a dry box: no cooling unit, no insulation rated for frozen product, and a routing model built on terminal transfers where freight sits on ambient docks between linehauls. Frozen food fails on every one of those points. The freight that survives is the freight that stays on refrigerated equipment from dock to dock with as few door openings as possible. Warp moves frozen food two ways: refrigerated box trucks for pallet-scale shipments (1 to 12 pallets, dispatched direct with liftgate available, priced per pallet with no reefer surcharge) and refrigerated 53-foot trailers for full loads. Both run at the setpoint on your BOL — 0 F or below for most frozen product — and both skip the terminal network entirely, which is the point: fewer touches, less dwell, product that arrives at the temperature it left at.
Pre-freezing and packaging that holds temperature
Refrigerated equipment holds temperature; it does not create it. Product must be frozen solid to its holding temperature before the truck arrives — tendering warm product to a cold truck is the single most common cause of rejected frozen freight. Freeze cases for 24 to 48 hours, stage them in the freezer until the truck is at the dock, and load fast. Palletize in an interlocking brick pattern so airflow stays consistent through the load, keep cases inside the pallet footprint, and wrap with five or more layers of film. If the pallet will sit on a dock at any point, an insulated cover buys hours of protection. Record the pulp temperature at pickup on the BOL — that number is your evidence if anything is disputed at delivery.
Cold-storage receiving without surprises
Frozen receivers run tighter docks than dry warehouses: appointment windows are enforced, lumper and staging rules vary, and almost every receiver checks product temperature before signing. Book the delivery appointment when you book the freight, and give the receiver the carrier and trailer details in advance. On arrival the receiver pulls a case, reads the temperature, and accepts or refuses on the spot — which is why transit time and pre-freezing matter more than any paperwork. If your volume is a full trailer, a refrigerated 53 with a drop appointment is the cleanest path; for 1 to 12 pallets, a refrigerated box truck delivering direct on a scheduled window avoids the multi-stop exposure entirely.

Frozen Food shipping FAQ
Can I ship frozen food via LTL freight?
Not on standard LTL — standard trailers are not temperature-controlled and frozen product will not survive the terminal network in any season. Frozen food ships on refrigerated equipment: a refrigerated box truck for 1 to 12 pallets moving direct, or a refrigerated 53-foot trailer for full loads. Warp runs both, priced per pallet on the box truck side with no reefer surcharge.
What temperature does frozen food ship at?
Most frozen food holds at 0 F or below in transit; ice cream and some seafood run colder, at minus 10 to minus 20 F. Put the required setpoint on the BOL — the driver runs the refrigeration unit to what the paperwork says, and the receiver checks product against it at delivery.
What freight class is frozen food?
Cased frozen food is dense and typically falls in the class 55 to 85 range, with tightly cased protein and prepared meals at the low end. Frozen foods are commonly cited under NMFC 26460 (foodstuffs, frozen, NOI) — confirm the exact item and class for your product before booking.
How is frozen freight priced?
On Warp, pallet-scale frozen shipments price per pallet on a refrigerated box truck with no reefer surcharge — the rate you see covers the temperature-controlled move, including liftgate where needed. 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 frozen volume weekly.
Why do frozen shipments get rejected at delivery?
Two reasons dominate: product tendered above its holding temperature (the equipment maintained temperature, but the product started warm), and dwell — too many hours on docks with doors open. Both are prevented at origin: freeze solid before pickup, record pulp temperature on the BOL, book a delivery appointment, and use direct dispatch instead of terminal routing.
