Red Sea routing is changing: 7 checks for Vietnam–Europe bookings

On 12 August 2026, the International Maritime Organization said the cargo ship TIHAMAH had been hit by a projectile off Al Mokha, Yemen, and that several seafarer fatalities had been confirmed. IMO called on shipowners and operators to assess risks before transit and follow appropriate best-management practices.

At almost the same time, an official Hapag-Lloyd notice said the Gemini Asia–South Europe SE4 service, operated with Maersk, was moving from the Cape of Good Hope route to the Red Sea route. The first westbound sailing named in that notice is Berlin Maersk. Maersk calls the paired service AE19; its original March launch notice described an Asia–Mediterranean/Jeddah rotation routed around the Cape.

These two facts do not prove that the Red Sea is closed, that every Asia–Europe service has returned through Suez, or that every Vietnam booking will be delayed. They show why the service and voyage now matter more than a generic carrier schedule.

What the latest carrier snapshot actually says

Hapag-Lloyd's Week 33 operational update, last updated 12 August, records a specific SE4 adjustment: Seaspan Pride voyages 624W/633E would omit Jeddah, while Maersk Lebu voyages 631W/633E would cover a Port Said–Jeddah–Port Said loop.

The same update reported Jeddah yard density of up to 71%, with reefer capacity at 63%, and Salalah yard density of up to 78%, with berthing delays of up to 36 hours. Those figures are a dated carrier snapshot for named terminals and services. They are not a forecast for every port, carrier, or Vietnam–Europe shipment.

The key operational message is therefore mixed: one Gemini service is taking a shorter Red Sea/Suez corridor, while the security event and nearby port adjustments show that the execution environment remains fluid.

Why this matters for Vietnam cargo

SE4/AE19 does not need to call a Vietnamese port for a Vietnam shipment to use it. A booking can move by feeder from Vietnam to a Southeast Asian hub and then connect to the mainline service. Whether that happens depends on the actual booking confirmation and transport plan.

If the mainline voyage changes from the Cape to Suez—or changes again after booking—the impact may appear in the transshipment connection, estimated arrival, empty-container plan, delivery appointment, inventory buffer, cargo-insurance file, or charges allowed by the contract. The direction and size of the impact cannot be known from the public notice alone.

For urgent exports, the safer commercial promise is based on the confirmed voyage and current transport plan, not on an assumed “normal” Asia–Europe route.

Seven checks before cargo release

• Identify the mainline service and voyage in writing. Record the feeder leg from Vietnam, the transshipment hub, mainline vessel, discharge port and final delivery point.
• Ask whether the confirmed voyage is planned through the Red Sea/Suez Canal or around the Cape of Good Hope. Do not infer the route from the carrier name alone.
• Recheck the plan at booking confirmation, shipping-instruction cut-off, container gate-in and before promising the customer's delivery date.
• Compare the carrier's current ETA with the sales contract, documentary-credit window and buyer's receiving appointment. Use a documented buffer rather than an unverified fixed delay assumption.
• Ask the carrier or forwarder to itemise any security, contingency, amendment, cancellation, storage or rerouting charge that can apply, including the contractual trigger date. Do not treat a charge on another trade as universal.
• Send the planned route to the cargo insurer or broker and request written confirmation of any war-risk, geographic, notice or deviation conditions. This article does not interpret an insurance policy.
• Agree a contingency decision with the buyer: who approves a route change, who pays the resulting cost under the chosen Incoterm, and when air freight, split shipment or inventory substitution becomes worth considering.

Freight impact and confidence

For Vietnamese exporters and importers, the immediate risk is not a confirmed universal surcharge or a proven corridor-wide delay. It is planning against a route that may not match the named voyage. A route mismatch can leave production, documents, insurance and destination delivery working to different dates.

Confidence is high in the IMO incident statement, Hapag-Lloyd's SE4 routing notice, the 12 August carrier snapshot and Maersk's original AE19 service description. Confidence is medium for any individual Vietnam booking until the live booking confirmation, vessel schedule, transshipment plan, quote and insurance terms are checked. The security and operating situation can change after publication; verify again before cargo release.
