Siam City Cement Plc (SCCC) plans to reduce its cement export volume next year to 34% of total output from 44.2% this year, in order to take advantage of rising domestic demand. At the same time, the company has raised its ex-factory prices by an average of 200 baht per tonne. Managing director Marcel Smit said the higher prices would result in the firm passing on 60% of its cost increases to customers.
