According to foreign media reports, EU officials revealed the five major criteria for exemption put forward by the United States to the EU and focused on whether the other party has contributed to solving the global excess production capacity. U.S. President Trump signed an order on March 8th that, on the grounds that imported steel and aluminum products threaten U.S. national security, he decided to fully impose taxes on imported steel and aluminum products at rates of 25% and 10% respectively. The new order will officially enter into force on March 23 and the EU hopes to seek exemption before this. EU officials stated that the five major criteria for exemption put forward by the United States are as follows. First, whether the country has used trade defense measures to prevent steel products suspected of dumping from entering the domestic market. Second, whether the country had supported the anti-dumping and countervailing duty investigations proposed by the United States in the World Trade Organization. Third, whether the country has participated in the Global Steel Overcapacity Forum. Fourth, the United States will also refer to the historical trading volume of steel and aluminum related to the country for the purpose of deciding on the annual quota granted to the country's tariff exemption. Fifth, whether the country is a US “security partner”. This is the first time that the public has been informed of the Trump administration's criteria for tariff exemptions. Previously, the Trump administration is secretive about the criteria and will also link European tariff exemptions with European tariff barriers, threatening the EU that it will impose punitive tariffs on cars imported from the European Union.
