U.S. President Donald Trump's threat to impose reciprocal tariffs from early April is feeding anxiety in India's export sectors from autos to agriculture, with Citi Research analysts estimating potential losses at about $7 billion a year.

Reciprocal and retaliatory tariffs are imposed by countries to match hikes in duties or high tariffs by trading partners.

Goldman Sachs analysis predicts Trump's reciprocal tariffs on Indian imports could reduce GDP growth by 0.1% to 0.6%.
