What Is a Freight Fee? Base Rate, Surcharges, and Who Pays

A freight fee is the amount a carrier charges to transport your goods from one place to another. It combines a base rate — driven by distance, weight, and how the commodity is classified — with surcharges for fuel and any service that falls outside standard dock-to-dock delivery. What lands on your invoice is rarely a single number; it is a base charge plus a stack of line items reflecting how and where the shipment moved.

What the Fee Actually Pays For

The base charge covers the carrier’s cost of moving your shipment plus a margin. That includes driver wages, fuel, vehicle maintenance, insurance, and terminal operations. When you book a shipment, the carrier issues a bill of lading, which functions as a receipt for the goods, a contract of carriage, and proof that the carrier accepted the shipment in the condition described.¹ The bill of lading also carries the freight classification code the carrier uses to price the move.

Rates in the United States are largely market-driven. Carriers set their own pricing, subject to competition on each lane.

How the Base Rate Is Built

Three variables drive the base rate: how far the shipment travels, how much it weighs, and what freight class it falls into. Distance is measured by mileage software or regional zones. Weight is either actual scale weight or dimensional weight, whichever is greater.

Freight Class

The National Motor Freight Classification system sorts commodities into 18 classes numbered 50 through 500, based on four traits:²

Density: how much space the cargo takes up relative to its weight.
Handling: how hard it is to load and move.
Stowability: how well it fits alongside other freight.
Liability: the risk of damage, theft, or harm to nearby shipments.

Lower class numbers mean lower shipping costs. Dense, easy-to-handle goods like bricks fall into Class 50. Lighter or more fragile items land higher, and bulky, high-value goods such as plasma televisions can reach Class 250 or more.²

Dimensional Weight

Carriers do not price by scale weight alone. They also charge for the space a shipment occupies. Dimensional weight is calculated by multiplying the length, width, and height of a package in inches and dividing by a standard divisor.³ The most common divisor is 139, though some carriers use 166 on retail-rate shipments.⁴ Whichever number is greater — actual or dimensional — is what the carrier bills. A light but bulky box of foam can cost as much to move as something much heavier of the same size.

Surcharges You May See on the Invoice

Beyond the base rate, carriers add accessorial charges for anything outside standard dock-to-dock service. These appear as separate line items and can quickly overtake the base charge on a small shipment.

Fuel Surcharge

Nearly every freight shipment carries a fuel surcharge tied to national diesel prices. Carriers adjust it regularly, often weekly, and it is usually stated as a percentage of the base rate.

Liftgate, Residential, and Inside Delivery

If the delivery location has no loading dock, the driver needs a liftgate to lower the freight to ground level. Liftgate fees vary; one major national carrier charges a minimum of $207 per shipment for liftgate service in 2026, up to $681 depending on weight.⁵

Residential delivery surcharges apply when the carrier has to navigate neighborhoods instead of a commercial dock. Parcel-sized shipments run around $6 to $7 per package, but freight-sized shipments can reach $230 per shipment. Inside delivery, where the driver moves the goods beyond the dock or curb into a specific room, starts at about $160 per shipment on express freight services.⁶

Detention

Detention charges kick in when the carrier’s truck waits at your facility past the agreed free time for loading or unloading. Free time is typically one to two hours depending on the contract. After that, charges accrue in short increments, sometimes per 15-minute block, and can reach several hundred dollars per hour.

Hazardous Materials

Shipping dangerous goods triggers extra charges for specialized handling, documentation, and compliance. For 2026, surcharges on accessible dangerous goods range from $185 per package for domestic overnight services to $270 or more per shipment for international express freight.⁶ Inaccessible materials carry lower surcharges, and dry ice adds roughly $8.50 per package or shipment.

Limited Access Delivery

Deliveries to construction sites, schools, churches, self-storage facilities, and gated communities often incur a limited access fee. These sites cause delays and require extra maneuvering. The exact amount is set out in the carrier’s rules tariff.

Reconsignment and Redelivery

Changing a shipment’s destination mid-transit triggers a reconsignment fee, often a flat charge around $50 per shipment plus any difference in freight to the new destination. If a shipment is already tendered and then refused, you pay both the reconsignment fee and a redelivery charge calculated by weight, which can run into several hundred dollars.

How the Mode Changes the Math

Pricing logic shifts depending on how the freight moves.

Less Than Truckload (LTL): you share trailer space with other shippers, so price turns on freight class, weight, and the floor space you occupy. LTL fits shipments too large for parcel but too small to fill a trailer.
Full Truckload (FTL): you book the whole trailer, and pricing is a flat rate per mile or a fixed rate per load. Freight class matters less; distance, weight limits, and equipment do.
Air freight: rates track the ratio of weight to volume. Worldwide average rates were roughly $2.65 per kilogram in late 2025, with spot rates somewhat higher, and prices move with demand and fuel.
Ocean freight: pricing is set per container, typically a 20-foot or 40-foot box, and moves with port congestion, seasonal demand, and global trade conditions. In early 2026, spot rates for a 40-foot container from the Far East to the U.S. West Coast hovered around $1,900, and rates to the East Coast averaged closer to $2,700.

Who Pays

Who owes the freight fee depends on the terms of sale. Under freight prepaid terms, the seller pays the carrier before delivery. Under freight collect terms, the buyer pays when the goods arrive.

International shipments are often governed by Incoterms, the 11 standardized trade terms published by the International Chamber of Commerce that define each party’s responsibilities for costs, risk, and logistics. Terms like Free on Board (FOB) and Ex Works (EXW) fix the exact point where risk of loss passes from seller to buyer. One distinction to keep in mind: Incoterms allocate cost and risk, but they do not determine when legal ownership of the goods transfers. That is governed by the sales contract itself.⁷

Checking the Invoice

Freight invoices are not always right. Industry estimates put billing discrepancies at roughly one in five invoices — wrong freight class, duplicate charges, weight errors, or surcharges for services never performed. Common items to check against the bill of lading and your contracted rate:

Freight class higher than what your commodity actually qualifies for.
Estimated weights that do not match the actual scale weight at pickup or delivery.
The same accessorial fee billed twice on one shipment.
Residential fees on commercial deliveries, or liftgate charges when a dock was available.

If you find overcharges, federal law gives you 18 months from the delivery date to file a civil action to recover. If you file a complaint with the Surface Transportation Board instead, you have three years. Both deadlines extend by six months if you submit a written claim to the carrier within the original limitation period and the carrier partially or fully denies it.⁸

Bringing the Fee Down

Freight rates are negotiable, and a few steps can lower what you pay:

Get quotes from several carriers on the same lane and use them as leverage.
Commit volume to a carrier over a set period to unlock lower per-shipment rates.
Tighten packaging to reduce dimensional weight on lightweight, bulky goods.
Verify your NMFC classification; shippers sometimes default to a higher class than the commodity requires.
Consolidate smaller shipments, especially when it lets you move from LTL to full truckload.
Audit every invoice against the contracted rate before paying.
