What is reefer LTL?

How refrigerated LTL works, what temperatures it covers, how it differs from dry LTL and full reefer truckload, and when it is the right choice.

Short answer

Reefer LTL is less-than-truckload shipping on a refrigerated trailer. A few pallets of frozen, chilled or temperature-protected freight share a reefer with other shippers' cold freight, so you keep the cold chain without paying for a full refrigerated truck.

How it works

Refrigerated LTL carriers run scheduled consolidation routes. Freight is picked up, held in temperature-controlled space, combined with other orders heading the same way, and delivered on a planned route. Because the schedule is route-based, pickup and delivery days are less flexible than dry LTL, and lead time matters.

Multi-temperature trailers use insulated bulkheads to hold separate zones, so frozen and chilled products can often ride on the same truck.

What you need to quote it

  • Pickup and delivery ZIP codes
  • Pallet count, dimensions and total weight
  • The required temperature or range
  • The commodity, and whether it is food grade
  • The receiver's appointment and unloading rules

When to choose a full reefer truck instead

Once a shipment reaches roughly 10 to 14 pallets, a dedicated refrigerated truckload is often cheaper and faster, and it removes the consolidation schedule. Price both when you are near that range.

Common questions

Is reefer LTL more expensive than regular LTL?

Yes. Refrigerated equipment, fuel for the cooling unit and a smaller carrier network make it cost more than dry LTL, but far less than a full refrigerated truck for a small shipment.

How long does refrigerated LTL take?

It depends on the consolidation schedule for the lane. Regional moves can deliver in a few days; cross-country moves take longer than dry LTL because freight waits for the scheduled route.
