The figures were the same unadjusted or work-day adjusted.
Growth slowed from 17.7 percent according to unadjusted figures and from 15.1 percent after workday-adjustment in August. The reason for the lower figures was in part a high base: twelve-month output in September 2009 was the highest in the first nine months of the year, KSH said.
Export sales rose by 13.0 percent in September from the same month a year earlier and domestic sales climbed 3.9 percent.
In a month-on-month comparison, output rose a seasonally- and workday-adjusted 0.5 percent in September after increasing 2.3 percent in August.
Output climbed 10.2 percent in January-September from the same period a year earlier.
