She also highlighted a positive aspect, saying that the labour market continued to improve, with manufacturers further increasing staffing, and October's activity similar to the pace seen in September's 59-month high.
Input costs and output charges both rose at faster rates in September.
While the bulk of new business came from domestic orders, exports continue to rise, albeit at a slower pace.
At 50.3 in October, the Nikkei India Manufacturing Purchasing Managers' Index (PMI ) fell from 51.2 in September.
Stephen Cooper, Head of industrial manufacturing at KPMG, said: "The UK's manufacturing industry remains resilient, with the latest figures marking 15 consecutive months of expansion".
"In response to weakening business conditions, the manufacturing sector decreased payroll numbers for the first time in four months, and at the greatest extent since August 2016".More news: Jahlil Okafor may request buyout from Philadelphia 76ers
Further reports also suggest that growth activity is expected to increase gradually to 7.4 percent by 2020, driven by a recovery in private investments which continues to face several domestic hurdles like corporate debt, regulatory and policy challenges and the risk of an imminent increase in United States interest rates.
More than 50% of manufacturers surveyed said they expected output to be higher in one year's time. "There was further evidence of material shortage impacting the sector, leading to higher input costs and delivery delays", Andrew Harker, associate director at IHS Markit, said.
"India's manufacturing companies struggled somewhat as the recent recovery enjoyed by the sector lost impetus in October". Production increased at a marginal pace that was the weakest in the current 12-month sequence of expansion. "Inflows of new orders stagnated as the negative effects arising from the implementation of GST continued to dampen demand".
Despite a positive outlook and continued growth for United Kingdom manufacturing, cost pressures continue to build. Selling price inflation is now at the highest level for six months and input costs are rising at the fastest for seven months. Foreign demand contracted at the fastest pace since September 2013.
"Business confidence eased to the weakest since February as some firms expressed concerns over negative GST effects", Aashna Dodhia, Economist at IHS Markit, said.
