A quoted air freight rate is one number per kilogram. The invoice that follows carries six or more lines, and the difference is rarely explained before it arrives.
Most of those lines are legitimate and some are fixed by the carrier. A few are set by the forwarder and move if you ask. This page covers which is which.
What Is an Air Freight Surcharge?
A surcharge is a charge added to the base air freight rate to cover a cost that moves independently of the rate itself. Fuel, security screening, insurance and seasonal demand all change faster than published rates, so carriers hold them separately rather than rebuilding the rate each time.
The base rate buys carriage between airports. Everything else is layered on top of it.
This matters because a rate quoted without surcharges is not comparable to one quoted with them. Two quotes can differ by thirty percent and describe identical service, simply because one is a base rate and the other is an all-in.
Which Surcharges Appear on an Air Freight Invoice?
Seven appear regularly, and they come from two different places. Some are set by the carrier and passed through unchanged. Others are the forwarder’s own charges.
| Charge | Code | Set by | Charged on | Negotiable |
|---|---|---|---|---|
| Fuel surcharge | FSC | Carrier | Chargeable kilogram | No at carrier level |
| Security surcharge | SSC | Carrier | Chargeable kilogram | No |
| War risk surcharge | WRS | Carrier | Chargeable kilogram | No |
| Peak season surcharge | PSS | Carrier | Chargeable kilogram | Rarely |
| Dangerous goods surcharge | DGR | Carrier | Per shipment or per kilogram | No |
| Air waybill fee | AWB | Forwarder | Per air waybill | Yes |
| Amendment charge | CCA | Carrier | Per amendment | No, but avoidable |
Two things follow from that table.
The carrier-set charges are not a negotiation. They are published, applied to everyone on the lane, and a forwarder quoting you a lower FSC is absorbing it out of their own margin rather than obtaining a better one.
The forwarder-set charges are a different matter. Documentation fees, handling fees and administration charges are the forwarder’s own pricing and they move with volume.
All of the per-kilogram charges apply to chargeable weight rather than actual weight, which means a low-density consignment pays surcharges on the volumetric figure.
How Is the Fuel Surcharge Calculated?
Against a published fuel index, in fixed steps, with the rate set by the flight date. Carriers publish the method openly, and the mechanism is more transparent than most shippers assume.
One carrier’s published methodology works like this. The index is built from US Energy Information Administration jet fuel data. The surcharge moves in steps of ten cents per kilogram for every five points the index moves. Below an index of 100 the surcharge is nil. Changes are announced fifteen days before they take effect, and the rate applied is the one in force on the flight date rather than the booking date.
| Index band | Surcharge per kg |
|---|---|
| 1 to 104 | 0 |
| 105 to 109 | 0.10 |
| 140 to 144 | 0.80 |
| 180 to 184 | 1.60 |
| 195 to 199 | 1.90 |
Those bands are one carrier’s published scale, shown to illustrate the mechanism rather than as an industry rate. Every carrier publishes its own, and they differ.
Three practical points come out of it.
- The flight date sets the rate. A booking made before an increase still pays the new rate if the flight departs after it
- Fifteen days notice is typical, so an increase is visible before it lands
- The index is public, so the surcharge is checkable rather than something to take on trust
If a forwarder cannot tell you which index their FSC follows, they are reselling someone else’s number without reading it.
What Is a Security Surcharge and Can It Be Waived?
It covers mandatory cargo screening, and no, it cannot be waived. Screening is a regulatory requirement rather than a service, so the cost applies to every consignment regardless of what it is or who is shipping it.
The charge is per chargeable kilogram and set by the carrier.
One related charge is worth knowing. Cargo moving under a known consignor or regulated agent arrangement may be exempt from physical screening at the terminal, because it was screened earlier in the chain. That does not remove the security surcharge, though it can remove screening delay, which is often the more valuable outcome. See air cargo handling for where screening sits in the process.
What Is a War Risk Surcharge?
A charge covering the higher insurance and security costs of operating through high-risk or conflict-affected airspace. It is applied per kilogram on the master air waybill chargeable weight, and it is becoming a standard line rather than an exception.
Carriers have introduced these network-wide rather than lane by lane, which is the part shippers find counterintuitive. A consignment that never approaches a conflict zone can still carry the charge, because the carrier’s insurance premium is written across its whole operation rather than per route.
The charge moves with the carrier’s own insurance costs and is reviewed as those change. Like the fuel surcharge it is published, applied uniformly, and not open to negotiation at carrier level.
This is the newest line on most invoices and the one most likely to appear without explanation. If it is on your invoice and was not on your quote, the quote predates its introduction rather than being wrong.
What Is a Peak Season Surcharge?
A temporary charge applied when demand exceeds available capacity on a lane. It appears in the run-up to retail peaks and around major disruptions, and it comes off again when capacity recovers.
Peak season surcharges differ from the others in one important way. They are a market response rather than a cost pass-through, so they are the one carrier charge with any room in it, usually for committed volume rather than for a single booking.
Planning around them is more effective than arguing about them. Booking ahead of a known peak, or shifting a flexible consignment outside it, avoids the charge entirely. The wider picture on how capacity drives pricing is in air cargo rates.
Which Surcharges Are Negotiable?
The forwarder’s own charges, and almost nothing else. The carrier-set charges are published and applied uniformly, so a forwarder cannot obtain a better FSC, only absorb part of it.
That absorption is the thing to understand when comparing quotes.
- A lower all-in rate usually means the forwarder has discounted its own margin, not that it has a better fuel surcharge
- A quote with no surcharges listed is a base rate, and the surcharges will arrive later
- An all-in or net net rate bundles everything into one figure, which is easier to compare but hides what moves when fuel does
The last point matters on a long contract. An all-in rate agreed when the fuel index was low will be reopened when it rises, because the carrier charge underneath it moved. Knowing which part of the number is fixed and which part floats tells you where the quote is exposed.
Ask for the breakdown even when you intend to take the all-in. A freight forwarder that will not itemise a quote is not necessarily hiding anything, but you cannot compare it with one that will.
What Charges Appear at Destination?
A separate set, usually billed by a different party. The origin quote covers origin charges and carriage. Import handling, customs clearance and delivery are charged at the other end and often by the destination agent rather than by your forwarder.
The common destination charges are terminal handling, breakdown or deconsolidation, customs clearance, storage if the cargo is held, and final delivery.
Storage is the one that surprises people. Cargo held for customs inspection accrues storage at the terminal, and so does cargo nobody has arranged collection for. If the consignment arrived in a container that also came off the airport, there is a second clock running, covered in ULD demurrage.
Under most Incoterms the destination charges fall to the buyer, which is why a seller quoting door to door and a buyer receiving an unexpected invoice are both looking at correct paperwork.
How Do You Read a Quote Properly?
Four questions turn a rate into a comparable number.
- Is this a base rate or an all-in? If surcharges are not listed, they are not included
- Which charges are carrier-set and which are yours? This tells you what is actually negotiable
- Which fuel index does the FSC follow, and what is it now? A forwarder who cannot answer is passing on a number they have not checked
- What is charged at destination and by whom? The origin quote usually says nothing about it
Ask all four at quoting stage. The surcharges on an air freight invoice are mostly legitimate, mostly fixed and mostly predictable, and almost all of the frustration around them comes from meeting them for the first time on the invoice.
For how the base rate itself is built before any of this is added, see air freight rates.
Questions About Air Freight Surcharges
What does FSC mean in air freight?
Fuel surcharge. It is a per kilogram charge set by the carrier against a published jet fuel index, added to the base rate to cover fuel price movement between rate revisions.
How is the air freight fuel surcharge calculated?
Against a published fuel index in fixed steps. One carrier’s published scale moves the charge by ten cents per kilogram for every five index points, with changes announced fifteen days ahead and the rate set by the flight date.
Are air freight surcharges negotiable?
Carrier-set charges are not. Fuel, security and war risk are published and applied uniformly, so a forwarder offering a lower rate is absorbing part of it. The forwarder’s own fees, such as documentation and handling, do move.
Why is my air freight invoice higher than the quote?
Usually because the quote was a base rate and the surcharges were added afterwards, or because the fuel surcharge changed between booking and flight. Destination charges billed by the receiving agent are the other common cause.
What is a war risk surcharge on air cargo?
A per kilogram charge covering higher insurance and security costs from operating through high-risk airspace. Carriers apply it network-wide rather than by route, so it can appear on a lane nowhere near a conflict zone.
Do surcharges apply to chargeable weight or actual weight?
Chargeable weight, the same basis as the freight rate. A low-density consignment therefore pays surcharges on its volumetric figure rather than on what it weighs.
