Common Freight Accessorial Charges Explained
An accessorial is a charge for something beyond ordinary dock-to-dock pickup and delivery. These charges are the most common reason a freight invoice arrives higher than the quote — and most of them are avoidable with information supplied up front.

Why accessorials exist
A standard freight rate assumes a standard move: the carrier's driver arrives at a commercial location with a dock, the freight is loaded and unloaded by facility staff within a reasonable time, and the trailer is released. An accessorial applies when the actual job involves something outside that assumption — waiting, a second attempt, special equipment, or a location that is not a dock.
The important thing to understand is that accessorials are conditional, and the conditions belong to the carrier. What triggers a charge, how much free time is allowed before detention begins, and how a location is classified all come from the individual carrier's service guide or rules tariff — not from a universal industry standard. Two carriers can treat the identical delivery differently.
That is why the practical advice is always the same: describe the shipment and both locations accurately when you request options, and confirm what is included in the quote rather than assuming.
Common accessorials, and what to confirm
The table below covers the situations that come up most often. The "information to provide" column is the part that prevents surprises — supplying it up front is what lets the charge be quoted rather than billed later.
| Service or charge | Situation to discuss | Information to provide | What to confirm in the quote |
|---|---|---|---|
| Liftgate service | No dock or forklift at pickup or delivery, so the freight must be raised or lowered between ground level and the trailer bed. | Which end needs it, the weight and dimensions of each handling unit, and how many units. | Whether liftgate is included at the required end, and whether weight or dimension limits apply to the equipment. |
| Limited-access location | A location that is harder to serve than a standard commercial dock — a site with restricted entry, narrow access, or non-standard hours. | The exact nature of the restriction, and the vehicle size that can physically reach the point of delivery. | Whether the location is treated as limited access by this carrier, and what that adds. |
| Residential location | Delivery to a residence rather than a commercial facility. Often paired with a liftgate need. | That the address is residential, plus unit weights and dimensions. | Whether the carrier serves residential addresses, what the classification is, and whether a liftgate is included or extra. |
| Inside service | Freight must be moved inside the building beyond the dock or threshold, rather than left at the loading area. | How far inside, and what is being moved — because inside service may be limited by weight or piece size. | Whether inside delivery is available for this freight, to what point, and what it costs. |
| Appointment or notification | The receiving location requires a booked delivery window, or requires advance notice before the driver arrives. | Whether an appointment is mandatory, how far in advance it must be booked, and the receiving hours. | Whether scheduling is included or carries a separate charge, and who books the appointment. |
| Detention / waiting time | The driver is held at a facility beyond the free time allowed for loading or unloading. | Realistic loading and unloading time at each end, and whether the facility is usually congested. | The free time allowed by this carrier before detention begins, and how it is measured. |
| Redelivery | A delivery attempt fails — the facility is closed, no one can receive, or the shipment cannot be unloaded — and the freight is delivered on a second attempt. | Accurate receiving hours and a contact who can accept the freight. | What triggers a redelivery charge, and what the process is if the first attempt fails. |
| Storage | Freight sits at a terminal beyond the free period, typically after a failed delivery or when a consignee delays receipt. | Confirmation that the consignee is ready to receive on the planned date. | Whether free time applies, how long it is, and what storage costs after it expires. |
About these definitions
The descriptions above are general explanations of what each situation involves. The specific conditions that trigger a charge — free-time allowances, how a location is classified, weight limits on liftgate equipment — are set by each carrier in its own service guide or rules tariff. Those terms vary between carriers and can change. Confirm the terms that apply to your shipment with the carrier handling it, rather than treating any figure here as universal.
Billing adjustments are a separate category
Reweighing and reclassification are sometimes grouped under "accessorials," but they are a different thing and worth keeping separate in your thinking.
An accessorial is a service the shipment actually required and which may not have been in the original quote. A reweigh or reclassification happens when the carrier's inspection finds the shipment differs from what was declared — heavier than stated, a different freight class, or packaged differently. The rate is then adjusted to match what was actually moved.
The practical difference matters because the fixes differ. Accessorials are managed by disclosing requirements up front. Reweighs and reclassifications are managed by declaring accurate information in the first place — correct packaged weight, correct dimensions, a specific commodity description, and an accurate unit count. If the declared figures are right, there is nothing to adjust.
Both types of charge land after delivery, often weeks later, which is what makes them disruptive. Neither is a guarantee of a particular outcome — a carrier's right to reweigh or reclassify comes from its own tariff terms, which is another reason to read what applies to your shipment.
Questions to ask about what is included
Is this included, or additional?
A quote that says "liftgate service" may mean the liftgate is included in the price, or it may mean the quote assumes a liftgate will be needed and the charge is added at billing. Those are not the same thing. Ask which accessorials are built into the quoted figure and which are billed separately if they occur.
What makes this charge conditional?
Most accessorials have a trigger. Detention starts after a free-time allowance expires; redelivery applies only after a failed attempt; storage accrues after a free period. Ask what the trigger is and what the threshold is, so you can judge whether your shipment is likely to hit it.
Whose terms apply?
Freight moves under the carrier's rules tariff. That document — not a general expectation and not another carrier's policy — is what governs the shipment. If a specific charge matters to your decision, have the applicable term pointed out.
What if something changes after booking?
Shipments change: a receiving window moves, a unit count changes, a delivery address is corrected. Ask how changes are handled and whether they re-rate the shipment, so a last-minute adjustment does not become a surprise on the invoice.
Confirm before booking
| Ask | Why it matters |
|---|---|
| Is there a dock and forklift at both pickup and delivery? | Determines whether liftgate service is needed at either end. |
| Is either location residential, limited-access, or restricted in entry? | These classifications affect both serviceability and cost, and vary by carrier. |
| Does the receiver require an appointment, and how far ahead? | Appointment requirements affect scheduling and may carry a separate charge. |
| What are the realistic receiving hours, and who can accept the freight? | Reduces the chance of a failed delivery and a redelivery charge. |
| How long will loading and unloading actually take? | Realistic timing tells you whether detention free time is likely to be exceeded. |
| Which accessorials are included in the quoted figure? | Separates what you are paying for from what may be billed later. |
| What is the free time, and how is it measured? | Detention and storage terms differ between carriers. |
| Has anything about this shipment changed since it was booked? | Changes can re-rate a shipment; catching them early avoids billing surprises. |
None of this requires predicting every eventuality. It requires describing the shipment and both ends of the move accurately, and asking what the quote does and does not cover — which is a short conversation at booking that saves a longer one at invoicing.
If you are unsure whether your shipment needs a liftgate, an appointment, or other special handling, describe what you know and flag what you have not confirmed.
On carrier-specific terms. The conditions described in this article are general explanations of common accessorial situations. Specific free-time allowances, location classifications, weight limits, and charge amounts are set by each carrier in its own service guide or rules tariff and are not reproduced here, because they vary by carrier and change over time. Where a specific charge affects your decision, confirm the applicable term with the carrier handling the shipment.
