The main purpose of this legislation is to strengthen the existing ban on importing oil and energy products from Russia. It aims to prevent the importation of energy products that are produced at refineries outside of Russia but still use Russian crude oil. This move is intended to further limit the economic benefits that Russia could gain from its oil exports, particularly in light of geopolitical tensions. The key provisions of this legislation include a clear prohibition on importing any energy products that are made at refineries using crude oil sourced from Russia.
