When a carrier publishes a date through Suez, the temptation is to treat the whole Asia–Europe network as reopened. History says the opposite: named voyages come back first, and they stay reversible.
Two dated sailings are now on customer schedules. Premier Alliance’s ONE Continuity is on a Laem Chabang window around October 19, with The Loadstar citing Ocean Network Express’s pro forma for a November 9 Suez arrival and a November 19 Rotterdam call. Linerlytica printed October 17 as the first-call date. Until the carrier picks one, that is a two-day window, not a berth hour.
Maersk’s own notice dated September 28 names Umm Qarn as the first AE12 vessel to transit Suez in both directions. Last Asian call: Tanjung Pelepas, October 27, voyage 642W. Hapag-Lloyd calls the same loop SE1. Both carriers have said each transit stays subject to a security review.
Those dates change one booking question: is this shipment on that ship? They do not change the load you can still build if the ship goes the long way instead.
This is a load-plan note. It is not a carrier schedule and not a security forecast.
Why a pro forma is a weak planning object
A pro forma is a published intention. A completed transit is a fact. Between those two sit weather, naval escorts, a projectile in the Gulf of Aden, and a last-minute Cape routing.
If you rebuild the carton file around a seven-to-ten-day shorter transit, and the ship then goes via the Cape of Good Hope, you have the wrong cutoff, the wrong warehouse appointment, and sometimes the wrong container type. If you keep the Cape plan and the ship does go Suez, you are a few days early. Early is cheaper than a restack at cutoff.
Hold two plans:
- Plan S: the named sailing, with the shorter transit and the earlier European window.
- Plan C: the same carton list in the same box, priced and timed as if the ship still goes south.
The carton list does not change between those plans. The cutoff and the all-in rate might. Fit the cargo once. Price both options when the forwarder can quote them.
What actually changes on the floor
A Suez return on one loop does not move your carton dimensions. It can move:
- Cutoff. An October 19 Laem Chabang departure is not an October 27 Tanjung Pelepas departure. The warehouse date is the one on your booking, not the one in a trade-press headline.
- Transit time. Cape routings have been adding roughly a week or more on Asia–North Europe. If you promised a customer the shorter window, say so only after the carrier confirms the itinerary in writing.
- Equipment. A ship that was on a South America loop (ONE Continuity was) may not offer the same high-cube mix you assumed on a Cape service.
- Insurance and emergency freight. A dated Suez sailing can still carry a war-risk or emergency line. The index rate for Shanghai–Rotterdam does not include that line.
Drewry’s October 1 World Container Index printed Shanghai–Rotterdam at $3,399 per 40-foot, down 2 percent and in a twelfth straight weekly fall. That average is useful as a direction. It is not the all-in on a named sailing that may still go Cape.
Rebuild only when the physical inputs change
Restack when quantity, dims, or container type change. Do not restack because a newspaper says “carriers are returning to Suez.”
Useful sequence:
- Freeze the carton file for this shipment.
- Optimize into the box the dock can accept. Save utilization and leftovers.
- Ask the forwarder whether the booking is on ONE Continuity, Umm Qarn, or a Cape vessel. Get the cutoff in writing.
- Price the plan you already trust. If the sailing flips, update the rate and the appointment. Keep the same 3D plan unless the box type changes.
Palletizr holds that file. Enter cartons, optimize for space, add the ocean rate when it lands. Fit the cargo. Compare two packing scenarios before you throw one away: scenario compare.
What a dated sailing is not
It is not an all-clear for the Red Sea. United Kingdom Maritime Trade Operations has kept writing attack warnings in the Gulf of Aden in the same week these pro formas circulated.
It is not a reason to drop the Cape buffer on every Asia–Europe purchase order. One FE1 ship and one AE12 ship are two ships.
It is not a change to Panama. Advisory A-36-2026 still sets Neopanamax draft at 49.0 feet and adds a tenth Neopanamax slot for booking dates beginning October 15. That is a different canal and a different decision.
The calculator does not pick the canal. It keeps the physical plan ready for whichever ship you actually get.
As of October 3, 2026. Confirm the itinerary with the carrier before you promise a customer the shorter transit.
