National Defense Supply Chain Integrity Act of 2025

Renames a subsection of an existing Defense Authorization provision and adds a rule that decisions made by the Secretary of Defense under that provision are to be treated as military or foreign affairs functions. Those Secretary-level determinations are declared not subject to many provisions of the Administrative Procedure Act, reducing the applicability of standard federal rulemaking and administrative procedures to those actions.

The change narrows procedural and judicial oversight for specific DoD determinations by categorizing them as inherently military/foreign affairs functions, which typically receive greater deference and are exempt from many APA requirements.
