The US Commerce Department issued a statement on the 29th that US President Trump signed an announcement on the same day, allowing targeted relaxation of import quota restrictions on steel and aluminum products in South Korea, Argentina, and Brazil.

The statement said that the United States has imposed import quota restrictions on steel products in South Korea and Brazil and steel and aluminum products in Argentina. However, if US steel and aluminum producers are unable to provide sufficient quantity and quality of products, US companies can apply to the US Department of Commerce for import quota exemption. . If the application is approved, these products will not occupy import quotas and will not be subject to customs duties.

Trump announced on March 8 that due to the "national security" of imported steel and aluminum products, the United States will impose tariffs of 25% and 10% on imported steel and aluminum products, respectively. The Trump administration's tariff measures for steel and aluminum products in most economies came into effect on March 23, and tariff measures for steel, aluminum and aluminum products in the EU, Canada and Mexico came into effect on June 1. In addition, some countries such as South Korea, Brazil, and Argentina have agreed to impose quota restrictions on steel or aluminum products exported to the United States in exchange for tariff exemptions.

The Trump administration’s decision to impose tariffs on steel and aluminum products was strongly opposed by the international community. The European Union, Canada, Mexico and other economies have taken countermeasures against US steel and aluminum tariffs and filed a complaint with the World Trade Organization dispute settlement mechanism.
