Cement is a controlled item and action under the Control Of Supplies Act could be taken against industry players found to increase the price without the government's approval, he added.
A non-civil aircraft, suspected to be a controlled item, was impounded Sunday, the spokesman said, adding the container was destined for the United States via Hong Kong.
Mukherjee said that the Central Government had listed petrol as a decontrolled item and had no control over the prices of the commodity, whereas the price of diesel was kept in check, as it was a controlled item.
It is considered a controlled item under the Emergency (Prohibition of Uniform and Dress) Regulation 1974 with compulsory clearance for usage obtained from the Federal Management Department.
