Recent reports show a notable increase in claims linked to off-specification bunker fuel, posing significant operational challenges for shipowners. This surge is particularly pronounced in China, where the Maritime Safety Administration (MSA) has intensified its enforcement of fuel quality standards.
The issue of bunker quality has been a persistent concern in the maritime industry, with previous analyses in early 2026 already highlighting a rise in such incidents. The current situation suggests that global fuel supply chains continue to face pressure, contributing to inconsistencies in the quality of bunkers delivered to vessels.
For freight forwarders and operations managers, this trend means a heightened risk of vessel delays and potential disruptions to shipping schedules. Off-spec fuel can cause engine damage, necessitating repairs and leading to vessels being taken out of service. This directly impacts transit times and can incur additional costs for demurrage or alternative cargo arrangements. Forwarders should advise shippers to factor in potential delays and ensure robust contingency plans are in place, especially for shipments involving calls at Chinese ports. The increased scrutiny by Chinese authorities implies that vessels bunkering or operating in Chinese waters are more likely to face inspections and potential penalties if fuel quality is found to be substandard.
