For the month new orders and backlogs were down 2.0 points and production slid 1.8 points. Inventories at manufacturers ticked down, but customer stock levels jumped six points.
Employment, at 48.8, failed to grow, ending a streak of 18 months.
The Electronic Components and Equipment sector reported growth during the month.
In a press statement, ISM chairman Norbert Ore questioned whether the improving dollar and high energy costs were to blame. "The manufacturing sector is definitely slowing, and the question is whether a somewhat stronger dollar and the burden of high energy costs are slowly bringing this manufacturing growth cycle to end."
