New Delhi has been cutting back on trade with North Korea but has maintained diplomatic links. It has given food aid in the past, but even that has been brought down to the minimum.
The new restrictions were mainly on "new or used vessels", food and farm products, electrical equipment and wood, the government said in the statement.
Curbs have also been toughened on the export of industrial machinery, transportation vehicles, iron, steel and other metals.
Washington has been leading diplomatic efforts to ramp up international pressure on North Korea. The US State Department said on Tuesday it had imposed the new sanctions.
North Korea has boasted of its plans to develop a nuclear-tipped missile capable of reaching the mainland United States. But fears of all-out war eased last month, coinciding with North Korea's participation in the Winter Olympics in the South.
North Korea seems "sincere" in its apparent willingness to halt nuclear tests if it holds denuclearisation talks with the United States, Trump said on Tuesday, as US, South Korean and Japanese officials voiced scepticism.
