The seasonally adjusted IHS Markit India Manufacturing Purchasing Managers’ Index® (PMI®) was at 55.5 in April, littlechanged from March's reading of 55.4.
Consumer goods was the strongest-performing category, followed by capital goods and then intermediate goods.
"The PMI results for April showed a further slowdown in rates of growth for new orders and output, both of which eased to eight-month lows amid the intensification of the covid-19 crisis," Pollyanna De Lima, Economics Associate Director at IHS Markit, said in a press release on Monday.
"Still, the increases were strong by historical standards and the survey revealed other positive news," De Lima stated.
While output and sales increased at the slowest rates since last August due to an intensification of the covid-19 crisis, there was a faster upturn in international orders.
Moreover, quantities of purchases expanded at one of the strongest rates seen for over nine years as firms sought to boost their inventories.
Survey participants also signalled a steep increase in input costs, the quickest since July 2014, and upward revisions to selling prices.
"The headwinds facing manufacturers cannot be ignored, however. The surge in covid-19 cases could dampen demand further when firms' financials are already susceptible to the hurdle of rising global prices," De Lima stated.
"Data for the coming months will be important at verifying whether client demand is resilient to these challenges or if producers will have to further absorb cost burdens themselves to secure new work," the official added.
