Homegrown auto major Tata Motors is optimistic that the supply constraint of semiconductors that has impacted its commercial vehicles production will be back to normal by the second half of the next fiscal, according to a senior company official. The company, which had hiked prices in October and January to offset the impact of rising commodity rates, is looking at taking a similar step in April in the wake of continued increase in steel and other raw material prices. "In H2 (second half of the ongoing fiscal), we have also seen the semiconductors becoming a major constraint. This is something which has actually affected us in the commercial vehicles (CVs) also," Tata Motors President Commercial Vehicle Business Unit Girish Wagh told PTI.
