Matson Inc. is poised to increase its fuel surcharge by 4.5 percentage points next month, likely adding to the costs of goods consumers will eventually pay.

The state’s largest ocean carrier announced Friday that it will boost the fuel surcharge to 43.5 percent from 39 percent on Oct. 7 for its mainland-Hawaii service as a result of rising bunker fuel prices and other energy-related costs. 

The fuel surcharge for Matson’s Guam, Commonwealth of the Northern Mariana Islands and Micronesia services will rise to 40 percent from 35.5 percent the same day.
