What Are LTL Carrier Tariffs and How Do They Work?
LTL carrier tariffs are the pricing guides and rules carriers use to determine how much they charge to move a shipment. These documents (often digital databases now) outline base rates, discounts, fuel surcharges, freight classes, and accessorial fees.
Key Terms to Know:
Base Rate: The starting point of cost per hundred pounds (CWT), based on distance and weight.
FAK (Freight All Kinds): A pricing strategy that simplifies classification by grouping items together.
Freight Class: Based on density, stowability, handling, and liability (as defined by NMFC).
Accessorial Charges: Extra services like liftgate, inside delivery, or residential pickup.
Every time you request an LTL quote, the system references the carrier’s tariff rules to calculate the total charges.
The History and Evolution of LTL Tariff Rules
Historically, tariffs were tightly controlled by the federal government. Carriers filed uniform rates with regulators, and all shippers paid the same published prices.
The Motor Carrier Act of 1980 deregulated trucking, allowing carriers to set their own rates and negotiate contracts. This gave birth to the modern tariff system, where each carrier creates its own pricing logic.
With digital logistics platforms and widespread use of TMS, shippers now have access to:
– Real-time tariff databases
– Custom pricing agreements
– Volume discounts and spot rate flexibility
How LTL Tariff Rules Work Today
Carriers now integrate their tariffs into digital rate engines. When you enter shipment details, the TMS pulls tariff data in real-time to generate an accurate quote.
Even though it feels simple, many variables are evaluated:
– Class and dimensions
– Service level (standard vs. expedited)
– Lane optimization
– Fuel surcharge tables
– Contracted discounts vs. spot pricing
Common Tariff Rule Scenarios:
– Minimum Charge Rule
– Reweigh/Reclass
– Oversize Penalties
Tariff Pause 2025: What Shippers Need to Know
A temporary tariff pause is planned for Q2 2025 as part of industry standardization discussions.
– Carrier contracts remain active but changes to published tariffs may be restricted.
– Spot rates may increase, especially in volatile or congested lanes.
– Shippers should review all active pricing agreements to avoid unexpected charges.
Simplifying Freight Through Smart Tariff Strategies
Reducing the number of carriers in your network helps consolidate volume, improve pricing leverage, and streamline tariff management.
Smaller, frequent LTL shipments are often costlier. Consolidating loads, avoiding dimensional surprises, and using the right freight class improves cost efficiency.
While spot quotes are flexible, they can be volatile. Contracted tariffs provide pricing stability, especially during market disruptions.
