MD Ankit Agrawal said that the company has about 20 per cent market share in Europe and between 10 to 12 per cent market share in the US. "We do see some inventory build-up in North America. We do expect probably another six to nine months for that inventory to reduce and then the demand to come back. Overall for this year, we do expect some volume decline. And probably from next year onwards, the volumes will come back," Agrawal said.
