Why are Maersk's partners exiting the Asia-South America service?

The article indicates Zim and CMA CGM are realigning their alliance partnerships. Zim moved to Hapag-Lloyd's AS3/ZFS service in September, while CMA CGM has chosen to end its joint ASAS2/SEAS3 service with Maersk, effective with the final Shanghai sailing on December 8. These exits reflect carriers' strategic decisions to restructure their network footprint on trade lanes where coverage has been informal or non-exclusive.

What should shippers do in response to these service changes?

Shippers are urged to verify their current routings immediately and confirm alternative capacity with carriers before December 8, when the Maersk-CMA CGM service terminates. This allows time to secure bookings on replacement services and adjust supply chain plans to avoid delays or service gaps on this Asia-South America lane.

Is this route going to lose shipping capacity altogether?

The article does not indicate that the Asia-South America lane will lose all capacity. Rather, Zim, CMA CGM, and other carriers are reorganizing how they serve this route through different alliance structures. Shippers will need to transition to the new AS3/ZFS service operated by Zim and Hapag-Lloyd, or identify other available carriers, rather than face a complete capacity shortage.

Why has this trade lane never been formally covered by alliances?

The article suggests this Asia-South America route has operated informally outside traditional alliance structures, likely due to lower volumes or strategic gaps in carrier networks. The current restructuring represents alliances actively formalizing coverage on this trade, signaling growing demand or carrier prioritization of this corridor.

How long do shippers have to make routing changes?

CMA CGM and Maersk's ASAS2/SEAS3 service is ending with the last sailing from Shanghai on December 8. Shippers should act immediately to identify and book alternative services before this date to avoid service interruptions.

Maersk Loses Partners on Asia-South America Route as Alliances Reshuffle

The signal

Maersk is experiencing significant disruption on the Asia to East Coast South America trade lane, losing both service partners within a three-month window. Zim departed the ASAS loop in September to join Hapag-Lloyd's AS3/ZFS alliance, followed by CMA CGM's announcement to end the joint ASAS2/SEAS3 service with a final Shanghai departure on December 8.

This rapid realignment represents a structural shift in how carriers serve this route, forcing shippers to actively reassess their logistics networks and confirm alternative routings. The consolidation signals a broader redrawing of alliance coverage on routes traditionally not formally represented by major alliances, creating near-term operational uncertainty for importers and exporters relying on these corridors.

Frequently Asked Questions

What This Means for Your Supply Chain

Simulation Suggestion

immediate

What if Asia-South America transit times increase by 1-2 weeks due to limited service availability post-December 8?

Simulate the impact of reduced shipping frequency and fewer direct sailings on the Asia to East Coast South America route after the Maersk-CMA CGM service ends. Model longer port queuing, mandatory transshipment via alternative hubs, and resulting lead time extensions for shippers relying on this corridor.

Run this scenario

Simulation Suggestion

What if shippers are unable to secure capacity on the new AS3/ZFS service and must book through secondary carriers?

Simulate cost and service level impacts if demand outpaces available capacity on Zim and Hapag-Lloyd's new AS3/ZFS service. Model spot market rate increases, reduced service level (slower transits via non-direct routes), and potential demand spillover to air freight or smaller carriers.

Simulation Suggestion

What if inventory buffers for South American imports must increase due to longer or more variable lead times?

Simulate the cost impact of raising safety stock for shipments on the Asia-South America route, accounting for increased transit variability, fewer sailing schedules, and potential service delays post-realignment. Calculate working capital implications and inventory carrying costs for importers.
