Neptune's latest bunker information update, covering data from April to September 2026, reveals a notable increase in off-specification marine fuel samples across various global ports. The report specifically points out high levels of technical non-compliance in both residual fuel oil (HFO) and low-sulfur fuel sectors. This trend indicates potential quality issues that could affect vessel operations and lead to increased maintenance or delays.
For freight forwarders and operations managers, this information is critical. Off-specification bunkers can cause engine damage, reduce vessel efficiency, and necessitate costly de-bunkering and re-bunkering operations, leading to significant delays in shipment schedules. Such incidents can also result in higher operational expenses for carriers, which may eventually be passed on to shippers through increased freight rates or surcharges. Forwarders should advise clients and carriers to exercise caution and implement robust bunker quality control measures when sourcing fuel in identified high-risk areas to mitigate potential disruptions.
