Accessorial charges
Additional fees carriers apply for services beyond standard shipping.
Definition
Accessorial charges cover extra services such as liftgate use, inside delivery, fuel surcharges, or redelivery attempts. They compensate carriers for tasks outside normal freight movement.
Overview of Accessorial Charges
Accessorial charges are fees applied by carriers — truck, parcel, or LTL — for services performed beyond the standard point-to-point freight movement included in a base rate. They are among the most significant sources of unplanned transportation cost for shippers, and for many businesses represent 15–35% of their total freight spend. Understanding which accessorials apply to your shipments, how carriers define them, and how to minimize or negotiate them is foundational logistics procurement knowledge. The most common accessorials in trucking and LTL include liftgate (delivery location lacks a dock, requiring a hydraulic tailgate), residential delivery (higher cost than commercial), inside delivery (carrier moves freight beyond the vehicle's tailgate), appointment scheduling, fuel surcharges (typically indexed to the DOE weekly diesel average), detention (carrier waiting beyond free time at pickup or delivery), layover, redelivery (failed first attempt), and hazardous materials fees. In parcel, accessorials include oversized package fees, address correction, signature required, and Saturday delivery. Each carrier defines trigger conditions slightly differently — a location one carrier considers commercial may be billed as residential by another. For warehouse operators and shippers using WareMatch, accessorial charges affect both inbound freight costs (receiving goods from suppliers) and outbound fulfillment costs (delivering to customers). A 3PL quoting a competitive per-pick or per-shipment rate may still produce an unfavorable landed cost if their carrier mix generates high accessorial exposure. When issuing RFQs on WareMatch, shippers should provide detailed shipment profiles — including delivery location types, average wait times at facilities, and freight dimensions — so that operators can quote accurate all-in rates rather than a base rate that swells with unbilled accessorials after go-live.

Benefits
- Understanding accessorials enables accurate freight cost modeling before signing contracts
- Allows shippers to design shipment profiles that minimize trigger conditions (e.g., adding dock equipment to eliminate liftgate fees)
- Provides leverage in carrier rate negotiations — accessorial caps and waivers are negotiable
- Enables accurate comparison of carrier quotes that differ in accessorial treatment
- Reduces invoice surprises and chargebacks from 3PL clients billing pass-through freight
- Supports cost allocation to business units or customers based on actual service consumed
- Drives facility investment decisions (adding loading docks eliminates recurring liftgate charges)
FAQs
Q: Which accessorial charges are most commonly disputed between shippers and carriers?
A: Detention and residential delivery are the most frequently contested. Detention disputes arise when shippers and carriers have different records of arrival and departure times. Residential vs. commercial classification disputes occur when a business operates from a home address or a commercial location that a carrier's algorithm codes as residential. Both are worth auditing quarterly.
Q: Can accessorial charges be negotiated down or capped in a carrier contract?
A: Yes, and this is standard practice for shippers with sufficient volume. Common negotiated terms include fuel surcharge caps, waived residential delivery fees for certain zip code ranges, free detention time extensions, and waived redelivery fees on the first occurrence. High-volume shippers should always negotiate accessorial schedules alongside base rates.
Q: How do fuel surcharges work, and why do they fluctuate so much?
A: Fuel surcharges are calculated as a percentage of the base rate, indexed to weekly diesel prices published by the U.S. Department of Energy. As diesel prices rise or fall, the surcharge percentage adjusts — typically weekly or monthly depending on the contract. During periods of high fuel prices, surcharges can add 25–35% to a base freight rate, making them the single largest accessorial for most shippers.
Q: Is there a way to audit accessorial charges for billing errors?
A: Yes — freight audit services (third-party or software-based) match carrier invoices against contracted rates and flag overcharges. Studies consistently show 2–5% of freight invoices contain errors, mostly in accessorial application. For shippers spending over $500K/year on freight, a freight audit program typically pays for itself many times over.
