Australia, Britain, Canada and the United States have imposed outright bans on Russian oil purchases following Moscow's invasion of Ukraine, but the European Union remains divided.
So far, the bloc's 27 members have been unable to agree on an embargo, with Germany warning against hasty steps that could push the economy into recession, and, some countries, such as Hungary, opposing any bans.
An EU embargo would require unanimous approval from all 27 member states.
Many buyers in Europe have shunned Russian crude voluntarily to avoid reputational damage or possible legal difficulty.
Others, such as commodity traders Trafigura and Vitol, have continued buying Russian crude under existing long-term contracts.
Both, however, told Reuters that they had not agreed any new deals since Russia's invasion of Ukraine, which Moscow calls a "special military operation" and which began on Feb. 24.
India and China, which have refused to condemn Russia's actions, also continued to buy Russian crude.
The following lists major takers of Russian crude:

A Bulgarian refinery, owned by Russia's Lukoil, and with Russian crude accounting for about 60% of its intake, continues to refine Russian crude.
