Guide to LTL Transport: 7 Things You Need to Know

This guide to LTL transport explains what to know about LTL transportation and the common LTL shipping mistakes to avoid.  

What Is LTL (Less-Than-Truckload) Transport? 

Less than truckload shipping moves freight that doesn’t require a dedicated 53-foot trailer. Your pallets ride with other freight on the same route, making it a cost-effective middle ground between parcel and full truckload. From single-pallet shipments to multi-pallet freight, up to 15,000 lbs, when freight is palletized or crated. 

Use LTL shipping for B2B orders, store replenishment, transfers to 3PLs and more. For larger or time-definite moves, consider guaranteed services, or partial truckload. 

Our Mainfreight National LTL network runs local pickups, consolidations at our branch terminals, linehaul to a destination terminal, and final delivery. Our linehaul strategy is built around running freight as direct as possible. Through zone skipping and direct linehaul movements, we reduce unnecessary handling movements, minimize crossing dock touches, and maintain greater control over your freight from pickup through final delivery.  

How LTL Pricing Works: Rates, Classes, and Density  

Rates reflect class, weight, distance (ZIP to ZIP), dimensions/density, carrier base rates, fuel surcharge, and accessorials. Understanding these items helps you budget, avoid re-bills, and prevent common LTL shipping mistakes. 

Freight class follows National Motor Freight Classification (NMFC) from 50 to 500, based on density, stowability, handling, and liability. Some commodities have specific NMFC items; others rely on density. If you ship the same product often, verify the correct item and packaging rules to prevent reclass. 

Density matters. Measure full L×W×H (including wrap/overhang), convert to cubic feet, then weight ÷ cubic feet. Higher density often means a lower class and better rate. Bulky, low-density freight may trigger dimensional rules in LTL truck freight pricing. 

Base rates are discounted by contracts; fuel varies with diesel prices; accessorials cover services like liftgate, inside or residential delivery, appointments, reweighs, and reclassifications. Minimum charges can apply. Put exact weight, dimensions, class, and services on the BOL for clean billing of your LTL shipment. 

We don’t simply quote freight we partner with customers to understand their shipping profile. By reviewing freight class, improving density, and identifying opportunities to optimize packaging or consolidate shipments, we help create long term transportation savings while maintaining service and network reliability.  

Packaging, Palletizing, and Preparing Your Freight 

Because LTL involves multiple touches, packaging is important. Use sound pallets, distribute weight evenly, avoid overhang, and stabilize with corner boards, edge protectors, stretch wrap, and strapping.  

Measure and weigh after final packaging. Record L×W×H to the farthest point, use a calibrated scale, and photograph the loaded pallet and scale readout. Mark stackable if it is; if not, label clearly - non-stackable can affect pricing. 

Label at least two sides with shipper/consignee details, ZIP codes, references, pallet count, and handling notes. Ensure the BOL matches labels and the packing list for your LTL shipment. 

Common LTL Shipping Mistakes and How to Avoid Them  

Most surprise fees come from wrong weights, dimensions, or missing services - top mistakes in LTL truck freight. Measure and weigh after packaging and list all needs on the BOL: liftgate, residential, limited access, inside, construction site, trade show, or appointments. 

Reclass happens when density or commodity details don’t match. Prevent it by citing the correct NMFC item when applicable, listing full dimensions and weight, and maintaining photos. Avoid detention by staging freight and confirming staffing/equipment; schedule earlier pickups and share site restrictions. 

Another common LTL shipping mistake is incomplete or mismatched paperwork. Include shipper/consignee, references, pallet and piece counts, class or density, NMFC item if known, accessorials, and the correct payer, and match the BOL to online bookings. 

Delivery rules vary across sites. Some facilities require appointments; homes need liftgates and have limited hours; schools, churches, and job sites may have limited access. Provide hours, dock height, forklift availability, and contacts to prevent redelivery or storage fees in less than truckload shipping. 

Insurance, Liability, and Claims 

Carrier liability is limited and not all-risk. Limits apply per pound and may vary by commodity. Declared value usually doesn’t raise recovery unless accepted. If your freight value exceeds limits, buy supplemental cargo insurance for your LTL shipment. 

Reduce risk with strong packaging and documentation. Photograph condition, labels, and scale readout before pickup. Keep the BOL, packing list, invoice, and handling notes. At delivery, note exceptions with specifics. Report concealed damage quickly—often within five days.

Dock & Loading Mistakes 

Loose products can shift during transit and increase the risk of damage. Boxes extending beyond the pallet edges are more susceptible to crushing and damage. Uneven or top-heavy pallets can tip over during loading and unloading. Broken or undersized pallets can fil during handling. Freight may sperate or move while in transit. Pallets should allow safe access from at least two sides to prevent handling issues.  

Delays occur when shipment labels or handling instructions aren’t visible. Weight, dimensions, freight class, and special service requirements should be confirmed before pickup. Freight should be palletized, wrapped, labeled, and staged before the driver arrives to avoid delays.
