DFARS Compliance and Non-China Sourcing: Your Domestic Supply Solution

In today’s defense procurement environment, meeting DFARS requirements is critical—especially when it comes to sourcing materials. The U.S. Department of Defense (DoD) mandates strict rules that favor domestic and allied-country suppliers while restricting purchases from China and other adversarial nations. At Stanford Optics, we specialize in offering DFARS-compliant fiber optic materials and components sourced from trusted domestic and allied manufacturers, ensuring your supply chain stays secure and compliant.

This guide explains what DFARS means for your sourcing strategy, why non-China materials are essential, and how partnering with a domestic supplier like Stanford Optics can help you succeed.

What Is DFARS?

DFARS, or Defense Federal Acquisition Regulation Supplement, is a set of procurement rules tailored specifically for the DoD. It builds on the broader Federal Acquisition Regulation (FAR) by adding extra requirements focused on national security, cybersecurity, and supply chain integrity.

Key focus areas include:

• Cybersecurity compliance, such as adherence to NIST SP 800-171

• Protection of Controlled Unclassified Information (CUI)

• Sourcing restrictions that prioritize domestic or allied-country materials over those from restricted countries like China

• Procurement rules for specialty metals, rare earths, and critical electronic components

In essence, DFARS ensures that all defense-related purchases meet stringent security and ethical standards.

Why Non-China Sourcing Matters

One of the most important aspects of DFARS is its emphasis on supply chain security. The regulation restricts sourcing from China due to national security concerns. This means components like semiconductors, optical parts, and specialty metals must come from domestic or allied sources.

Choosing non-China suppliers helps you:

• Avoid risks associated with restricted or adversarial countries

• Comply fully with DFARS sourcing clauses

• Maintain a transparent and traceable supply chain

• Support U.S. and allied manufacturing industries

Who Must Comply with DFARS?

DFARS applies to all contractors and subcontractors working with the DoD, including:

• Prime contractors bidding on or performing defense contracts

• Sub-tier suppliers providing components or services used in defense products

• Third-party providers handling sensitive defense data or logistics

Even foreign companies operating within the U.S. defense ecosystem must comply with applicable regulations.

Which Materials and Systems Are Covered?

DFARS covers a wide range of materials and systems critical to defense, including:

• Specialty metals such as titanium and nickel, which must be sourced from approved domestic or allied countries

• Electronic components, including semiconductors and optical parts like fiber optic cables

• IT and cybersecurity systems protecting defense networks

• Technical data and software requiring strict handling and protection

• Finished products that must be manufactured domestically or by allied nations

For fiber optic products and related optical components, DFARS compliance is essential if they serve defense contracts.

How to Achieve DFARS Compliance?

To meet DFARS requirements, companies should:

1. Carefully review DFARS clauses in their contracts and understand obligations

2. Implement cybersecurity controls aligned with NIST SP 800-171, including system security plans and self-assessments

3. Conduct thorough supplier audits to verify sourcing meets DFARS rules—no restricted countries allowed

4. Stay updated on regulatory changes through DoD notices or compliance experts

5. Train staff and prepare for audits to demonstrate compliance
