It was up from a growth of 3.1 percent recorded in March, driven by growth in factory prices in mining industry and raw material sector.

In the first four months, PPI rose by 3.6 percent year on year, easing from 3.7-percent growth in the first quarter.  

On a month on month basis, PPI declined 0.2 percent, according to the bureau.
