ZIM pulls out of Arkas–Evergreen Black Sea service

ZIM has terminated its slot-chartering arrangement on the GPM/BSX service jointly operated by Arkas and Evergreen, ending the Israeli carrier's presence on a regional container loop that connects Piraeus with three Black Sea gateways. The withdrawal strips shippers of a branded ZIM option — Black Sea Express (BSX — on a route whose rotation runs Piraeus – Poti – Constanta – Varna – Piraeus.

The mechanics matter here. ZIM was not operating vessels on the loop; it chartered capacity on the jointly run Arkas–Evergreen service and marketed that bought capacity to customers as its own Black Sea Express product. That commercial model is common on regional trades, where carriers buy slots rather than commit tonnage. It also means ZIM's exit is a commercial decision about a capacity purchase, not a withdrawal of ships.

What changes on the route — and what does not?

The underlying service continues. Arkas and Evergreen keep operating GPM/BSX, and the rotation — Piraeus, Poti, Constanta, Varna, and back to Piraeus — remains in place. Cargo flows between Greece and Georgia, Romania and Bulgaria will still have a direct regional connection, now carried under the two remaining operators' banners rather than ZIM's.

What disappears is ZIM's participation. Customers who booked Black Sea cargo through ZIM on this lane will need to move that volume: either to Arkas or Evergreen directly on the same ships, or to whatever alternative routing ZIM offers. On that point, the record is silent.

What ZIM has not said

Two gaps stand out. No effective date for the withdrawal has been provided, which leaves shippers uncertain whether existing bookings run for weeks or end immediately. And no details of alternative arrangements for affected customers have been announced — no replacement slot deal, no revised routing, no transition window.

For a carrier that has spent recent years promoting regional network expansion, an exit announced without a stated start date or a customer-migration plan raises an obvious question: is this a single slot deal being allowed to lapse, or a broader retrenchment from the Black Sea? ZIM has not said, and the announcement alone cannot answer it. The Black Sea itself has been a volatile market since the war in Ukraine redrawn regional trade patterns, and regional loops live on thin margins between Greece and the Georgian, Romanian and Bulgarian gateways they serve.

Commercial read-through for shippers and forwarders

The practical consequences fall into three buckets:

• Shippers moving Greece–Black Sea volumes under ZIM paper must re-paper their bookings with Arkas, Evergreen or another carrier; the physical ships on the rotation have not changed.
• Forwarders using ZIM as a single-carrier gateway into Georgia, Romania and Bulgaria lose that consolidation point and may need to split bookings across operators.
• Arkas and Evergreen gain freed-up capacity on the loop each week — capacity that, on a regional trade with limited alternatives, they can now sell directly or re-offer to another slot charterer.

The last point is the quiet variable. If another carrier steps into the vacated slots, the market impact is close to zero and the change is purely a logo swap. If the capacity sits unsold, Arkas and Evergreen face a utilization gap on a four-port loop that depends on steady Greece–Black Sea volume.

For now, the service itself — Piraeus to Poti, Constanta and Varna and back — continues uninterrupted under its two remaining operators, and ZIM has given no timeline for when its exit takes effect.
