A 40ft container that left Shanghai in the third week of July, booked at a rate you were happy with, is about to cost more than you agreed to pay. Not because the freight rate moved. Because on August 1 the carrier moving it started adding an Emergency Fuel Surcharge, or EFS, and it bills by the date the box loads, not the date you booked. Your box is already at sea. The charge is already yours.
CMA CGM set its EFS at $150 per TEU (twenty-foot equivalent unit) on long-haul head-haul lanes, effective August 1, 2026, based on loading date. On a standard 40ft dry container, which is two TEU, that is roughly $300 you never quoted. For a reefer, a refrigerated box, the figure is $165. Ocean Network Express, ONE, follows on August 15 at $75 per TEU and $100 per reefer, and it applies the charge on both Federal Maritime Commission (FMC) regulated and non-regulated long-haul trades. Other carriers are filing their own versions on their own dates.
The cause is not demand. It is bunker fuel. With the Strait of Hormuz, a corridor that historically carries about one fifth of the world’s oil and gas, back in conflict, marine fuel prices reversed the easing they had shown earlier in the month. Vessels rerouting by way of the Cape of Good Hope add roughly 3,500 to 4,000 nautical miles per voyage and burn the fuel to match. Carriers are passing that cost on as a surcharge rather than folding it into a base rate, because a surcharge can be filed fast and withdrawn fast. Unlike the General Rate Increases (GRIs) carriers announced earlier in July, which the market shrugged off inside a week, a fuel surcharge is not a bet on demand. It is a cost the carrier is already incurring on every sailing.
Why is my rate falling while my bill is rising?
Here is the part that catches importers out. The base rate is going down. Drewry’s World Container Index (WCI), in the week of July 30, 2026, put Shanghai to Rotterdam at $4,677 per 40ft, down 3 percent, with the Shanghai spot index posting its third straight week of decline. Read only the rate and you would plan for a cheaper third quarter. The transpacific told the same story that week: Drewry put Shanghai to New York flat at $7,578 per 40ft even as carriers pushed August GRIs of $2,000 to $3,000 per 40ft that the spot market had already undercut.
But the all-in delivered cost is not the base rate. It is the base rate plus surcharges, and the surcharge line is the one moving up. A falling rate and a rising surcharge net out to a bill that does not behave like the number you were watching. The quoted rate is a headline. The EFS is a footnote that lands on the invoice weeks later, after the box has already sailed under it.
Why does the loading date matter more than the booking date?
A surcharge billed at booking is at least predictable. You see it when you commit. An EFS billed by loading date is not. CMA CGM ties the charge to the loading date; ONE ties its FMC-scope charge to cargo gating in on or after the effective date. The trigger is a moment in the container’s journey, not a moment in your planning. A box you booked in mid-July at a clean number can cross an effective date while it is physically on the water, and inherit a charge that did not exist when you signed off on the shipment.
That breaks two assumptions importers lean on.
The first is that a locked rate is a locked cost. It is not. You locked the base rate. Surcharges sit outside the locked rate by design, which is the entire reason carriers use them. The rate is a contract. The EFS is a pass-through. Your fixed number was never the whole number.
The second is that reconciling surcharges at invoice has always worked fine. It worked when surcharges were stable and rare. It stops working when a surcharge appears mid-voyage, differs by carrier, differs by box type, and lands on dozens of shipments at once. Reconciling at invoice means you find the exposure after you could have done anything about it, after the box loaded, after the accessorial accrued, after the quarter’s landed-cost forecast was already wrong.
Put numbers on it. Say you have twenty 40ft dry boxes on long-haul lanes that load on or after August 1 with a carrier charging $150 per TEU. Twenty boxes at two TEU each is forty TEU, and at $150 that is $6,000 in EFS on that one carrier, on that one batch, none of it in the rate you quoted. Add the reefers at the higher figure, add a second carrier with its own August 15 date, and the number your forecast is missing keeps growing while the base rate you are watching keeps falling.
What would it take to see the charge before the invoice?
The problem is not that the surcharge is large. On a single box it is survivable. The problem is that the information you need to act on it, which carrier moved which container, whether it is dry or reefer, and where it sits against an effective date, lives in a different place for every carrier. One box is in one carrier’s portal, another in a second portal, a third in a forwarder’s email. No single view tells you which of your in-transit boxes are about to cross an effective date, so the exposure stays invisible until it is billed. The same fragmentation is what lets demurrage and detention ride quietly behind the same shipments.
This is what a consolidated operational desk is for. FrateZone puts milestone data from 200+ ocean carriers onto one screen, so every shipment carries its own status, its own carrier, and its own container type in one place. When a carrier files a surcharge tied to a loading or gate-in date, the boxes sitting on the wrong side of that date surface as carrier-driven exception flags against the shipments they belong to, not as a reconciliation surprise found weeks later. To be clear about what that is and is not: FrateZone does not send a push alert and does not let you set a custom dollar threshold. It gives you one version of the truth for every shipment on a single operational desk, so the exposure is visible where you already work, early enough to matter.
A checklist for the next two weeks
Before the next effective date lands, run four checks:
- List every in-transit box and the carrier moving it. The EFS differs by carrier and by date, so the carrier is the first fact you need.
- Flag the reefers. They carry the higher figure, $165 against $150 on CMA CGM, $100 against $75 on ONE.
- Find the boxes that load or gate in on or after each carrier’s effective date. Those are the ones inheriting the charge.
- Add the exposure to your landed-cost forecast now, not at invoice. A forecast that still reads the falling base rate is already wrong by the size of the surcharge.
None of this stops the surcharge. Nothing you do stops a carrier from filing an EFS. What it changes is whether the charge is a number you saw coming and planned for, or a number you discover on an invoice for a box that shipped a month ago. The rate you watch is the easy number. The bill you pay is the one that decides your margin.
The time lost waiting for containers costs far more than the freight itself. FrateZone enables real-time freight predictability across 200+ ocean carriers, turning your operational visibility into strategic program control. Learn more at https://www.fratezone.com/pricing.html.
