The decrease followed an unchanged reading in April that had originally been reported as a 0.5% decline.
The drop matched economists’ forecasts, Bloomberg reported.

Imported food costs declined 0.7%, while automobiles and parts slipped 0.1% in the first decline of the year.
U.S. export prices decreased 0.4%, following a 0.4% gain in April, Labor said.
