Maersk has warned customers that low water levels on the Amazon River could disrupt vessel operations to Manaus, Brazil, and potentially trigger a surcharge of up to US$4,646 per container if ships are unable to navigate the waterway as planned.
The warning reflects the seasonal challenges associated with navigating the Amazon River, where water levels can fall significantly during the dry season. Reduced draft restrictions can limit the amount of cargo vessels are able to carry and may affect the reliability of scheduled calls at Manaus.
If water levels deteriorate to a point where normal vessel operations become impractical, Maersk may need to implement contingency measures. These could include reducing vessel loads, adjusting cargo flows or making operational changes to maintain service continuity.
The potential surcharge is intended to address additional costs arising from such disruptions. Depending on the severity of the restrictions, shipping operations could require alternative arrangements that increase vessel, handling, inland transportation and other logistics expenses.
Manaus is an important commercial and industrial centre in Brazil’s Amazon region, but its geographical location means that maritime access depends heavily on navigability conditions along the Amazon River. Changes in river depth can therefore have a direct impact on the movement of containers and other cargo.
For exporters and importers using Manaus, the prospect of a substantial surcharge adds another cost consideration at a time when global supply chains are already facing elevated logistics risks. Shippers may need to review cargo planning and allow additional time for potential operational disruptions.
Low-water conditions can also affect vessel loading decisions. When draft restrictions are imposed, carriers may have to reduce cargo intake to ensure vessels can safely navigate shallow sections of the river. This can create additional capacity constraints and potentially lead to cargo being rolled to subsequent sailings.
Maersk’s warning gives customers advance notice of the potential financial impact should navigation conditions worsen. The actual application of the surcharge would depend on prevailing water levels and the operational restrictions affecting vessel movements to and from Manaus.
The situation highlights the vulnerability of river-dependent supply chains to seasonal changes in water levels. Continued monitoring of the Amazon’s navigability will be important for carriers and cargo owners as they plan shipments to the Manaus region.
