"We are looking and seriously examining other steps so that sectorally we can address the problem which can be defensive against dumping of steel in the country," he said at 'India Summit 2015' organised by The Economist magazine.
The government has twice increased tariffs on steel imports this year.
"As far as steel is concerned, we have to balance the interest of the consuming industry along with the steel manufacturing industry. It is an external issue. So we have marginally increased our tariffs twice," Jaitley said.
The DGS has initiated the probe after it found that "prima-facie increased imports of (certain kinds of steel) have caused or are threatening to cause serious injury to the domestic producers".
The domestic steel producers have complained of surge in imports of steel products like hot-rolled steel and other variants from China, Korea, Japan and Russia.
Last month, the government had hiked import duty on base metals, including iron and steel, by 2.5 per cent in a move aimed at helping domestic players battling cheap Chinese imports after the currency devaluation by China.
