What Is LTL Freight and How Does It Work?

LTL freight is a way to ship goods that don’t fill a whole truck. Your pallets ride on a trailer alongside freight from other shippers, and you pay only for the space and weight you use. For most businesses moving one to six pallets at a time, LTL is the cheapest way to ship by ground.

Below, we’ll walk through how an LTL shipment moves, how it’s priced, what freight class means, and the extra fees that catch new shippers off guard. We’ll also cover when LTL is the wrong choice.

What is LTL freight?

LTL (less-than-truckload) freight is a shipment too large for a parcel carrier but too small to justify a dedicated truck. Typical LTL shipments weigh between about 150 and 15,000 pounds and take up a few pallets’ worth of floor space. Carriers combine many of these shipments on one trailer to keep costs down.

Think of it like a bus instead of a taxi. You share the ride, so you share the cost. The trade-off is that the bus makes stops for other passengers, so your freight takes a little longer and gets handled more along the way.

LTL fits shippers who move freight regularly but not in full truckloads. That includes:

• Manufacturers sending parts or finished goods to distributors
• Wholesalers restocking retail stores
• Distributors filling mid-size customer orders
• Growing businesses that have outgrown parcel shipping

If your shipment is a box or two under 150 pounds, a parcel carrier is usually cheaper. If you’re filling most of a 53-foot trailer, you’re likely in truckload territory. LTL covers the large middle ground.

How does LTL shipping work?

LTL carriers run a hub-and-spoke network. A local truck picks up your freight and brings it to a nearby terminal, where it’s sorted onto a long-haul trailer with other shipments headed the same way. At the destination terminal, it’s unloaded again and put on a local truck for final delivery.

Here’s what that looks like for a typical shipment:

1. You request a quote and book the shipment. You’ll need the pickup and delivery addresses, pallet count, dimensions, weight, freight class, and any special services.
2. You prepare the freight and the bill of lading. The bill of lading (BOL) is the shipping contract and receipt. It tells the carrier what’s moving, where, and under what terms.
3. A pickup driver collects it. Local drivers run routes, so you’ll usually get a pickup window rather than an exact time. If your dock closes at 3 p.m. and the driver’s route puts him there at 3:15, the pickup slips a day.
4. The origin terminal sorts it. Your pallets are unloaded, checked, and loaded onto a linehaul trailer bound for the destination region.
5. Linehaul moves it between terminals. This is the long-distance leg. Longer lanes may pass through one or more additional terminals.
6. The destination terminal breaks it down. Freight is unloaded and loaded onto a local delivery truck.
7. The driver delivers it. The receiver inspects the freight, notes any damage on the delivery receipt, and signs.

Every handoff is a chance for a delay or a dropped pallet. That’s why packaging and accurate paperwork matter more in LTL than in truckload, where freight usually stays on one trailer from start to finish.

How is LTL freight priced?

LTL freight is priced on four main factors: freight class, weight, distance, and any extra services. Carriers start from a base rate per hundred pounds (called CWT, or hundredweight) for your class and lane, apply any discount you’ve negotiated, then add a fuel surcharge and accessorial charges.

Here’s how each piece affects your bill:

• Freight class. Lower classes cost less per pound. Dense, sturdy freight like machine parts ships cheaper than light, bulky freight like furniture.
• Weight. Rates are tiered. Heavier shipments get a lower rate per hundred pounds, so a 2,000-pound shipment costs more in total but less per pound than a 500-pound one.
• Distance and lane. Longer hauls cost more. Lanes with lots of freight moving in both directions are often cheaper than one-way lanes into rural areas.
• Minimum charge. Every carrier has a floor. Very small shipments pay the minimum no matter how light they are.
• Fuel surcharge. A percentage added to the line-haul charge, adjusted as diesel prices move.
• Accessorials. Fees for services beyond dock-to-dock pickup and delivery. More on these below.

One practical tip: compare quotes on the total, not the base rate. A low base rate with a high fuel surcharge or a long list of accessorials can end up costing more.

Some carriers also price certain freight by volume or density instead of class, especially larger shipments. If you’re shipping more than about six pallets, ask for a volume quote too.

What is freight class, and why does it matter?

Freight class is a number from 50 to 500 that tells an LTL carrier how easy or hard your freight is to handle. It’s set by the National Motor Freight Classification (NMFC), a standard published by the NMFTA. Lower classes are cheaper. Class depends mostly on density, plus how easily the freight is stowed, handled, and damaged.

There are 18 classes. A pallet of steel bolts might be class 50. A pallet of lampshades might be class 300 or higher, because it takes up lots of space for very little weight.

Density is the biggest driver, so it helps to know yours. Measure the shipment, including the pallet, and run the numbers:

For example, a 48 × 40 × 48-inch pallet is 92,160 cubic inches, or 53.3 cubic feet. At 800 pounds, that’s 15 PCF, which falls around class 70 on the density scale.

Getting class wrong is expensive. If the carrier inspects your freight and finds a different class or weight than your bill of lading shows, it issues a reclass or reweigh, and your invoice goes up. Accurate measurements and an honest class up front prevent most of these surprises.

What are accessorial charges in LTL shipping?

Accessorial charges are extra fees added to a freight bill for services beyond standard dock-to-dock pickup and delivery. They’re the most common reason an LTL invoice comes in higher than the quote. Nearly all of them can be avoided or planned for if you tell the carrier about them when you book.

The pattern is simple: accessorials come from surprises. The more the carrier knows at booking, the closer your invoice will match your quote.

How long does LTL shipping take?

Most LTL shipments deliver in 1 to 5 business days within a region, and longer cross-country. Transit time depends on distance, how many terminals the freight passes through, and whether the pickup or delivery point is in a remote area. LTL transit times are estimates, not guarantees.

A few things stretch transit time:

• Terminal transfers. Each extra stop in the network can add a day.
• Rural or out-of-network points. Some carriers hand off remote deliveries to partner carriers.
• Missed pickups. If the driver arrives after your dock closes, the clock doesn’t start until the next day.
• Peak season and weather. Capacity tightens in the fall and around holidays.

If a delivery date truly can’t slip — a line is down, a store opening is set, a customer contract has penalties — LTL isn’t the right tool. That’s when guaranteed LTL or expedited freight earns its cost.

LTL vs. partial truckload vs. full truckload: which should you use?

Use LTL for roughly one to six pallets when cost matters more than speed. Use partial truckload for larger shipments that don’t fill a trailer, when you want less handling. Use full truckload when you’re filling most of a trailer. Use expedited when the deadline matters more than the price.

How do I prepare an LTL shipment?

Prepare an LTL shipment by palletizing and wrapping the freight securely, measuring and weighing it accurately, labeling every pallet, and completing a bill of lading that matches what’s on the dock. Good prep is the cheapest way to prevent damage, delays, and reclass fees.

Use this checklist before the driver arrives:

• Freight is on a sound pallet, with nothing hanging over the edges
• Boxes are stacked in columns, heaviest on the bottom, with a flat top
• Pallet is stretch-wrapped and banded if needed
• Each pallet is labeled with shipper, consignee, and BOL or PRO number
• Dimensions and weight are measured with the pallet included
• Freight class and NMFC item are correct on the BOL
• Accessorials (liftgate, appointment, residential) are listed on the booking
• Dock hours and a contact name are confirmed at both ends

Take a photo of each pallet before it leaves. If anything arrives damaged, those photos make a freight claim much easier.

Frequently asked questions about LTL freight

What does LTL stand for?

LTL stands for less-than-truckload. It describes shipments that don’t need a full trailer, so they share space with freight from other shippers.

What’s the minimum size for an LTL shipment?

There’s no strict minimum, but LTL usually makes sense starting around 150 pounds. Below that, parcel carriers are often cheaper. Every LTL carrier also has a minimum charge, so very light shipments pay that floor regardless of weight.

Do I need a loading dock to ship LTL?

No. If either end lacks a dock, the carrier can send a truck with a liftgate to lower or raise the freight. That service carries an extra fee, so mention it when you book.

Who determines my freight class?

You do, as the shipper, based on NMFC rules for your commodity and its density. The carrier can inspect the freight and reclass it if the paperwork doesn’t match. If you’re unsure, ask your carrier or broker before you ship.

Is LTL freight insured?

Carriers have limited liability for loss or damage, often based on weight and freight class rather than the goods’ full value. For high-value freight, ask about added coverage before shipping. Noting damage on the delivery receipt protects your right to file a claim.
