The figure went up from the 10.7 percent year-on-year increase registered in September.
On a monthly basis, China's PPI rose 2.5 percent in October.
Specifically, the rising prices of international crude oil have driven the prices of domestic oil-related industries, with the PPI for the oil exploitation sector up 7.1 percent from a month ago, said senior NBS statistician Dong Lijuan.
Due to the tight supply of coal last month, the factory-gate prices for coal mining and washing industry increased 20.1 percent month on month, while that for coal processing industry saw 12.8-percent growth.
On a yearly basis, the prices of production materials went up 17.9 percent, 3.7 percentage points higher than the increase recorded in September.
