In a significant proclamation regarding the national security of the United States, President Joseph R. Biden Jr. has taken measures to address the potential threats posed by the importation of steel articles. The proclamation, titled "A Proclamation on Adjusting Imports of Steel Into the United States," emphasizes the need to safeguard the country's national security interests and protect vital industries.The proclamation builds upon previous investigations and findings by the Secretary of Commerce, who determined that steel articles are being imported into the United States in quantities and circumstances that could impair the nation's security. President Biden concurred with these findings and decided to impose a 25 percent ad valorem tariff on steel articles imported from all countries, except Canada and Mexico.However, recognizing the unique situation of Ukraine's steel industry, the President had previously suspended tariffs for steel articles and derivative steel articles from Ukraine. The latest proclamation extends this suspension, considering the continued disruption caused by the Russian Federation's unjustified war against Ukraine. The war has severely impacted Ukraine's steel production, reducing the total output and import volume to the United States.The proclamation is enacted under the authority granted by section 232 of the Trade Expansion Act of 1962, section 301 of title 3 of the United States Code, and section 604 of the Trade Act of 1974. These provisions empower the President to adjust imports that pose a threat to national security and embody such adjustments in the Harmonized Tariff Schedule of the United States (HTSUS).
