Matson announced Friday it is raising its fuel surcharge by 4.5 percentage points, from 39 percent to 43.5 percent, for its Hawaii service.
For its Guam and Micronesia services, rates are rising from 35.5 percent to 40 percent.
Both increases go into effect on Oct. 7.
The jump in the fuel surcharge comes after two consecutive decreases in June and July of 2012, which totaled 6.5 percentage points.
"While we were encouraged by the moderation of bunker fuel prices earlier this year, that trend has been reversed in recent months," said Dave Hoppes, senior vice president, ocean services. "Since announcing our last decrease in mid-July, bunker fuel prices have risen over 13 percent. Energy related expenses continue to be a significant cost factor for most businesses, as well as consumers, with transportation companies especially hard hit."
Matson said it gives customers 30 days advance notice prior to implementation.
