United States Steel Corporation (U. S. Steel) has filed its Specialized Disclosure Report (Form SD) for the reporting period from January 1, 2023, to December 31, 2023, as mandated by Rule 13p-1 under the Securities Exchange Act. The report addresses the company's use of conflict minerals, which are gold, columbite-tantalite (coltan), cassiterite, and wolframite, and their derivatives tantalum, tin, and tungsten, known as 3TG. These minerals are sourced from regions that include the Democratic Republic of the Congo and nine other central African countries. U. S. Steel's inquiry into its supply chain revealed that in 2023, the only products containing 3TG were its tin mill products with a tin coating and certain tubular mill products produced by its subsidiaries. The company confirmed that the 3TG used in its products did not originate from the covered countries or were from recycled or scrap sources. As a result, U. S. Steel determined that no further due diligence measures were required. The findings of this inquiry are available to the public on the company's website.
