India has also been demanding resumption of benefits under the American Generalised System of Preferences (GSP) scheme, and exemption from high import tariffs on steel and aluminium.The Trump administration had, in 2019, removed India from GSP scheme, a special trade treatment for developing countries, due to significant trade barriers in India. India was the biggest beneficiary of GSP in 2018. Over a tenth of US merchandise imports from India entered duty-free under the scheme. These exports, amounting to $6.3 billion, consisted of chemicals, auto parts, tableware etc. GSP removal meant imposition of US tariffs, which ranged 1-7 per cent on the top 15 GSP imports. Shortly after the US move, India had imposed retaliatory tariffs against the US, following which Washington filed a dispute at the WTO.
