Field guide

A short, plain-English guide for shippers who don’t ship every day. Freight class, accessorials, what a PRO number is, what can’t ride on a 28-foot pup. Written by people who answer the phone in Cedar Rapids.

01

What LTL actually is

LTL stands for less-than-truckload. It means your freight rides in a trailer with other shippers’ freight. You pay for the space and weight you use, not the whole truck.

Full-truckload is the alternative. You buy out a 53-foot trailer for a single shipment. Faster, more expensive, only worth it if you have enough freight to fill it. Most small businesses don’t.

LTL trades a day or two for a much lower bill. The truck stops at a few terminals along the way. Your freight gets sorted at each one. Sometimes it spends a night on a dock. That’s normal, and it’s why a Cedar Rapids to Des Moines run that would take a car ninety minutes is quoted as one business day.

02

Freight class, in plain English

NMFC class is the four-digit shorthand the freight industry uses to price your shipment. It runs from class 50 to class 500. Lower is cheaper.

Class is set by four factors. Density (pounds per cubic foot) does most of the work. Stowability is whether your freight stacks cleanly. Handling is whether it’s fragile or awkward. Liability is the dollar risk if it gets damaged.

The rule of thumb: dense, sturdy, low-value freight is class 50 to 100. Bulky, fragile, or expensive freight climbs from there. A pallet of bricks is class 50. A pallet of stuffed animals takes up the same space but weighs almost nothing, so it bills like class 250.

ClassDensityCommon items
5050+ lb/ft³Bricks, steel rod, palletized durable goods
7015 to 22 lb/ft³Auto parts, food cases, boxed appliances
92.510 to 12 lb/ft³Computers, monitors, packaged electronics
1257 to 8 lb/ft³Small countertop appliances, vacuum cleaners
1755 to 6 lb/ft³Boxed clothing, sofas, stuffed furniture
2503 to 4 lb/ft³Mattresses, large TVs, dishwashers
4001 to 2 lb/ft³Light fixtures, kayaks, wood crates of foam
500Under 1 lb/ft³Bags of feathers, ping-pong balls, gold dust
03

The lifecycle of a shipment

Five legs, in order. Most regional LTL shipments hit all of them inside two business days. The PRO number on your bill of lading is what you track. It gets scanned at every leg.

  1. Pickup

    Day 0, your window

    Driver pulls up in a 28-foot pup or a straight truck. You hand over the bill of lading. Driver counts pieces, weighs if needed, scans the pro, you sign.

  2. Origin terminal

    Day 0, evening

    Pup gets unloaded onto the dock back at the terminal. Your pallet is sorted by destination region and tagged for the overnight linehaul.

  3. Linehaul

    Overnight

    A linehaul tractor pulls a full trailer between terminals on the long-distance lane. This is the leg most shippers picture when they say trucking.

  4. Destination terminal

    Day 1, before dawn

    Trailer arrives at the destination terminal. Freight gets unloaded, re-sorted by city route, and handed off to the local delivery driver.

  5. Delivery

    Day 1 or Day 2

    City driver runs the route and delivers in the receiver's window. Receiver signs the delivery receipt. The pro closes.

04

Accessorials, the extras

Accessorials are the line items that get added when your shipment needs something beyond a standard dock-to-dock pickup or delivery. They’re not surprise fees. They cover real labor, time, or equipment. Tell us up front which ones apply and the quote stays the quote.

Liftgate
The truck has a hydraulic platform on the back that lowers freight to the ground. Required if there's no dock and the receiver can't unload from trailer height.
Residential
Delivery to a house or any address coded residential, including home-based businesses. Adds for the smaller truck and tighter access.
Inside delivery
Driver brings freight past the threshold, into a room or down a hallway. Without it, the contract is curbside or the first dry interior space.
Limited access
Schools, churches, military bases, mini-storage, farms, construction sites. Anywhere a driver needs an escort, gate code, or non-standard hours.
Notify before delivery
Carrier calls the receiver to schedule. Costs more than a standard window but prevents a redelivery if the receiver isn't going to be there.
Sort and segregate
Freight needs to be broken down by part number, store, or department on delivery. Adds dock labor at the destination.
Reweigh
Carrier weighs the shipment again on a certified scale. Triggered if the bill of lading weight looks off. The new weight rebills the shipment.
Redelivery
Receiver wasn't ready or refused on the first attempt. Charged per attempt. Calling ahead with a notify is almost always cheaper.
05

Packaging that survives

Most damage claims trace back to two things: pallets that fell apart in transit and freight that wasn’t shrink-wrapped down to the pallet. Both are avoidable.

Use new four-way pallets when you can. Stack to the corners, not pyramid-style. Don’t overhang the pallet edge by more than an inch. Shrink-wrap vertically and horizontally, five revolutions minimum, including the pallet boards themselves so the load and the pallet are one piece. Corner boards on top and along vertical edges take pressure off the box corners and stop side loads from caving.

If your freight is fragile, expensive, or both, build a crate. A simple plywood crate adds maybe forty dollars in materials and routinely saves a four-figure damage claim.

06

What can't ride LTL

A short list. Most freight rides LTL without an issue. These are the ones where you should call before booking, not after.

Hazmat without proper paperwork
Class 1 explosives, class 7 radioactives, anything requiring a hazmat endorsement. We can ship most class 3, 8, and 9 with the right BOL and emergency contact info.
Oversize freight
Anything over 12 feet long, 8 feet wide, or 8 feet tall on a single pallet. Long pieces need a flatbed, not LTL.
Single pallets over 5,000 lb
Rule of thumb. We can move heavier with the right rigging, but it stops being LTL and starts being a partial. Call us before you book.
Perishable without a reefer
Anything that needs temperature control. LTL trailers are not refrigerated. Frozen food, fresh produce, pharmaceuticals all need a different mode.
High-value without declared coverage
Jewelry, fine art, currency, prototypes. Standard cargo coverage caps out fast. If your shipment is worth more than the trailer, declare it and pay the higher class.
07

Glossary

BOL
Bill of lading. The shipping contract and packing list, signed by both ends.
Class
NMFC freight class, 50 to 500. Lower is cheaper.
Consignee
The receiver. The address freight is going to.
Density
Pounds per cubic foot. The biggest input to class.
Detention
Charge for keeping a driver waiting past the free loading time.
Dock
Raised platform at trailer height. Where freight gets loaded and unloaded.
Dolly
Wheeled hand truck. Also: the converter that turns a single trailer into a doubles set.
FAK
Freight all kinds. A negotiated single class for a shipper who moves a wide mix.
Linehaul
The long-distance run between terminals, usually overnight.
NMFC
National Motor Freight Classification. The book that assigns class to every commodity.
Pallet jack
The manual or electric tool that moves a pallet without a forklift.
PRO
Progressive number. The 9 or 10 digit tracking number on every shipment.

Weighing the freight again on a certified scale to verify the BOL.
Shipper
The sender. The address freight is leaving from.
Tare

Terminal
Hub where freight gets sorted between local pickup, linehaul, and local delivery.
Transit time
