The growth rate has dropped for four consecutive months.
Of major industrial sectors, producer prices in the sectors of chemical raw materials and products, nonmetal mineral products, ferrous metal processing, oil, coal and other fuel processing saw lower growth rate compared with those in September.
Friday's data also showed that the PPI rose 0.4 percent in October on a monthly basis, down from 0.6 percent registered in September.
Over the past 10 months, producer prices at the factory gate saw 3.9-percent rise year-on-year.
