From Borates.today, a bit more detail about the critical infrastructure status

5e Advanced Materials Critical Infrastructure Status

In late 2021, the Government singled out the company’s Fort Cady facilities in California for its reserves to be included as “in the interest of national security”.
5e Advanced Materials – formerly ABR – at Fort Cady Integrated Boron Facility has been designated as Critical Infrastructure by the Cybersecurity and Infrastructure Security Agency. The designation of  ‘Critical status’ is a sign that the US Government considers Fort Cady and its reserves to be in the interest of national security.
The designation validates Fort Cady’s role in providing a new, critical, domestic source of boron amidst a challenged global supply chain. CISA, as a U.S. federal agency and operational component under the Department of Homeland Security, is tasked with understanding, managing, and reducing risk to the nation’s cyber and physical infrastructure.
