The United States has sanctioned six Indian companies for allegedly engaging in significant transactions involving Iranian petrochemical and petroleum products, breaching US sanctions. The firms, which include some of India’s key petrochemical traders, are now blocked from accessing US assets and barred from dealings with American companies. These sanctions are part of a wider crackdown involving 20 entities across multiple countries, aimed at cutting off Iran’s oil-based revenue streams. The Indian firms have not publicly responded to the action.
