The commerce ministry is working on different scenarios to assess the possible fallout of reciprocal tariffs to be imposed by the US administration on April 2 on its key trading partners including India, sources said. US President Donald Trump has said that April 2 will be 'Liberation Day' as he plans to announce tariffs or import duties to bring down America's trade deficit, and promote the country's manufacturing. India and the US are also working on a bilateral trade agreement to promote two-way commerce and investments.
