The purchasing managers index (PMI) for the Russian manufacturing industry decreased to 52.6 in April from 53.2 in March, data provider S&P Global announced on Tuesday.
"Rates of inflation reached the fastest for a year as firms sought to pass through hikes in supplier prices to customers," it said.
Meanwhile, the manufacturing sector's output improved for a ninth month in succession in April.
"The pace of expansion eased slightly from that seen in March, however, reflecting a weaker rate of demand growth during the month," according to S&P Global.
In April, Russian manufacturers posted a modest upturn in the health of the sector, the data provider said, adding that overall growth was driven by further increases in output and new orders.
