CMA CGM will increase its Low Water Surcharge (LWS) to US$2,315 per TEU for shipments to and from Manaus, Brazil.
The new surcharge will take effect on 2 October 2026 and will apply to all equipment types.
The carrier said the measure comes as falling water levels affect navigation across the Amazon River system.
Amazon water levels fall rapidly
CMA CGM said water levels in the Negro and Amazon rivers fell faster in August than during the same period in recent years, except for 2024.
Conditions are now approaching the critical levels recorded in 2023.
The carrier cited a notice issued by the Western Amazon Harbour Master on 28 August.
Authorities assess navigation conditions using river levels, bathymetric surveys and information from river pilots.
In particular, surveys monitor critical areas such as Foz do Madeira and Tabocal.
Draft restrictions could begin in September
According to CMA CGM, authorities expect possible Maximum Recommended Draft (MRD) restrictions from mid-September.
Further reductions could follow if water levels continue to decline.
As a result, the carrier expects to adjust vessel capacity, port calls and cargo movements.
CMA CGM will also use a floating pier and make other operational and logistics adjustments.
The company said draft restrictions reduce available transport capacity. They also create additional costs for barges, storage, pilotage and infrastructure.
New surcharge effective from 2 October
The US$2,315 per TEU Low Water Surcharge will apply to shipments both to and from Manaus.
For the surcharge, CMA CGM will use the date when the cargo passes through the relevant river section, port or pier while onboard the vessel.
CMA CGM said it will continue to monitor water levels, bathymetric surveys and notices from port authorities.
The carrier may review the surcharge if navigation conditions change significantly.
