What is LTL Shipping?

If your shipment is too big for parcel but too small to fill a full truck, you ship LTL. It is the workhorse mode for most growing brands that move freight, and it usually costs a fraction of full-truckload pricing.

Here is what LTL shipping actually is, how it gets priced, and how to keep your costs in check.

What is LTL shipping?

LTL stands for less-than-truckload. It is a freight service for shipments that are bigger than a parcel but do not fill an entire truck. Most LTL freight runs between 150 and 15,000 pounds and ships on pallets.

Instead of paying for the whole truck, you pay for the space your pallets take up. The carrier fills the rest of the trailer with other shippers' freight heading the same direction. That sharing model is what makes LTL much cheaper than booking a full truck for one pallet.

How LTL works

LTL runs on a hub-and-spoke network. Your freight moves through a chain of terminals before it reaches the consignee:

Pickup

A local carrier picks the pallet up from your warehouse and brings it to a regional terminal.

Consolidation

At the terminal, your freight is sorted with other shipments heading to the same hub. The carrier loads a line-haul trailer with consolidated freight.

Line-haul and final mile

The trailer runs to the destination hub, gets sorted again, then a local truck handles final delivery. Most LTL lanes hit a 3 to 7 business day window depending on distance.

The US LTL market today

The US LTL market sits around $118 billion in 2026 and is growing at roughly 4% a year. Two forces are driving it: ecommerce brands moving inventory between fulfillment centers, and retailers pushing more replenishment freight as they move stock closer to consumers.

Carriers have also gotten more disciplined on pricing. Capacity is no longer being given away cheap, and the days of soft-market LTL rates are mostly over.

What LTL costs depend on

LTL rates are built from five inputs:

Weight and dimensions

Heavier and bulkier freight costs more. Carriers also apply dimensional weight, so a light but oversized pallet can be priced like a heavy one. See how DIM factor works for the math.

Freight class

The National Motor Freight Classification system assigns every shipment a class from 50 to 500, based on density, stowability, handling, and liability. Lower-class freight is cheaper. Class 50 is the cheapest, class 500 is the most expensive.

Distance

Longer lanes cost more. Inter-regional moves (West Coast to East Coast) carry the biggest premium.

Accessorials

Extras add up fast. Liftgate, residential delivery, inside delivery, limited access locations, and appointment scheduling all carry their own fees. If a quote looks cheap, look for accessorials missing from the line items.

Fuel surcharge

Every LTL carrier applies a fuel surcharge that moves with diesel prices. It is usually expressed as a percentage of the base rate.

When LTL is the right call

LTL is the right mode when:

You have between 1 and 6 pallets to move

The freight is palletized, stable, and not perishable

You can live with a 3 to 7 day transit window

You do not need the entire trailer

If your shipment is over 12 pallets or runs more than 15,000 pounds, full-truckload usually gets cheaper per pound. If you only have a few cartons, parcel may still be the better option.

Common LTL pitfalls

The most common reasons LTL invoices come in higher than expected:

Wrong freight class declared at booking. Carriers reweigh and reclass at the terminal and bill the difference.

Pallets that fall outside standard 48x40 dimensions trigger dim weight charges

Missing accessorials at booking (liftgate, residential, limited access) get added back as fees

Damage from poor palletizing, especially on multi-stop lanes where freight gets handled four or five times

Tight packaging is the cheapest insurance you can buy. Pallets should be stretch-wrapped, labeled clearly, and stable enough to take a forklift on three sides.

How 3PL Center handles LTL

3PL Center moves LTL freight every day from coast-to-coast warehouses. A few things that keep our clients' LTL costs down:

Rate shopping is built into our WMS, so each shipment gets compared across carriers before it ships

We use our discounted carrier rates instead of retail tariffs, which can cut LTL costs significantly. See our carrier rate program.

Cross-docking moves freight from inbound to outbound trailers without long-term storage

We pick same-day on outbound orders received by 2pm local, so LTL pallets do not sit waiting on the dock

For freight that crosses LTL and parcel modes, cross-docking and consolidation cut handling fees

Frequently asked questions

What size shipment qualifies for LTL?

Most LTL shipments are between 150 and 15,000 pounds and travel on pallets. Anything smaller usually ships parcel. Anything heavier or above roughly 12 pallets usually moves on a full truckload.

How is freight class assigned?

The NMFC assigns classes from 50 to 500 based on density, stowability, handling, and liability. Dense, stable, low-risk freight gets a lower class and a lower rate. Loose, oddly shaped, or fragile freight lands in a higher class.

How long does LTL shipping take?

Most LTL lanes deliver in 3 to 7 business days depending on distance and how many hubs the freight passes through. Regional LTL inside a single state or adjacent states is often 1 to 2 days.

What is a liftgate and when do I need one?

A liftgate is a hydraulic platform on the back of the truck that lowers freight to the ground. You need one when the delivery address does not have a loading dock or a forklift. It is an accessorial charge, so add it at booking to avoid a surprise rebill.

How can I cut my LTL costs?

Consolidate small shipments into fewer larger pallets, declare the right freight class up front, book accessorials at booking instead of after delivery, and use a 3PL with rate-shop tools so each shipment goes on the best-priced carrier for that lane.
