The Defense Federal Acquisition Regulation Supplement (DFARS) is a crucial regulatory framework that governs procurement within the U.S. Department of Defense (DoD). For organizations involved in the defense supply chain, understanding and complying with DFARS requirements is essential to ensure supply chain security and material integrity. Stanford Materials Corporation (SMC) provides rigorously vetted, domestically sourced, and non-China materials that meet DFARS standards, supporting defense contractors with traceable, high-performance solutions critical to national security.
Defense Federal Acquisition Regulation Supplement (DFARS) extends the Federal Acquisition Regulation with additional clauses tailored to the Department of Defense’s unique requirements. It mandates cybersecurity controls consistent with NIST SP 800-171 and imposes sourcing restrictions that prioritize materials produced in the U.S. or allied countries, explicitly excluding China. This regulatory framework is designed to protect sensitive defense technologies and maintain supply chain integrity.
Compliance is required for all contractors and subcontractors involved in defense contracts, including suppliers of components and service providers handling sensitive defense data. Even foreign entities operating within the U.S. defense supply chain may be subject to DFARS provisions, particularly regarding technical data and cybersecurity.
DFARS regulations extend beyond traditional specialty metals such as titanium, nickel, or steel to include critical rare earth metals widely used in defense technologies. Elements like neodymium, samarium, and their alloys—key components in high-performance magnets—are explicitly covered under sourcing restrictions. These materials must be mined, refined, or processed in the United States or allied countries, excluding China and other restricted sources.
Specifically, DFARS clauses 252.225-7009 and 252.225-7052 establish detailed requirements for specialty metals and rare earth magnets. Clause 252.225-7009 mandates that specialty metals—including titanium, nickel, steel, and their alloys—must be melted or produced domestically or in qualifying allied countries. The current list of qualifying countries includes Australia, Austria, Belgium, Canada, Czech Republic, Denmark, Egypt, Estonia, Finland, France, Germany, Greece, Israel, Italy, Japan, Latvia, Lithuania, Luxembourg, Netherlands, Norway, Poland, Portugal, Slovenia, Spain, Sweden, Switzerland, Turkey, the United Kingdom, and the United States.
Clause 252.225-7052 extends sourcing restrictions to rare earth magnets such as samarium-cobalt and neodymium-iron-boron, requiring full supply chain traceability by January 1, 2027.
From a materials engineering perspective, DFARS compliance ensures both provenance and performance. Our laboratory tests confirm that materials sourced through DFARS-compliant channels maintain thermal stability beyond 600°C and structural integrity under hypersonic stress conditions. These metrics are critical for aerospace and defense applications, where failure is not an option.
Contractors must:
Identify relevant DFARS clauses in contracts.
Implement cybersecurity measures aligned with NIST SP 800-171.
Assess and document supply chain risks to exclude restricted sources.
Maintain traceability and quality documentation.
Train personnel and prepare for audits.
Stanford Materials Corporation specializes in DFARS-compliant materials sourced exclusively from U.S. and allied manufacturers. Our products include rare earth metals and specialty alloys, each accompanied by detailed Certificates of Analysis. We validate material performance through multi-phase testing, focusing on ion mobility, thermal stability, and mechanical strength. Our team supports clients with data-driven insights to ensure compliance and optimize material selection.
