BIS Restricts Exports of Critical Mineral Materials to Protect National Security
The Bureau of Industry and Security (BIS) has issued a temporary final rule restricting the export of certain critical mineral materials, including 'black mass' from lithium-ion batteries and tungsten waste, to non-U.S. entities. This rule, effective from August 27, 2026, mandates that these materials be sold exclusively to U.S. buyers unless authorized by BIS. The decision follows a Presidential Determination highlighting the scarcity of these materials and their importance to national defense. The rule aims to secure domestic supply chains and mitigate risks associated with foreign dependency.
