FAR/DFARS Flowdown Clauses for Subcontractors: Complete Guide + Template
If your company supplies to aerospace or defense primes, you’ve likely received a purchase order or subcontract filled with unfamiliar clause references—FAR, DFARS, and other requirements that must be “flowed down.”
Understanding which clauses apply—and how to implement them correctly—is one of the most common challenges for suppliers.
This article explains what FAR/DFARS flowdowns are, why they matter, and what is typically included in a compliant subcontracting framework.
What Are FAR and DFARS Flowdown Clauses?
FAR (Federal Acquisition Regulation) and DFARS (Defense Federal Acquisition Regulation Supplement) clauses are regulatory requirements included in U.S. government contracts.
When a prime contractor issues a subcontract or purchase order, certain clauses must be:
“flowed down” to the supplier.
This means:
the supplier must comply with specific requirements
the clauses become part of the subcontract agreement
Why Flowdowns Matter for Suppliers
Flowdowns are not just administrative—they directly impact:
Compliance risk
Incorrect or missing clauses can create audit exposure or contractual disputes.
Performance obligations
Clauses may impose:
cybersecurity requirements
quality standards
reporting obligations
Export and data restrictions
Some clauses govern:
ITAR/EAR compliance
controlled information handling
Common FAR/DFARS Clauses Flowed to Subcontractors
While applicability depends on the prime contract, commonly included clauses may address:
Cybersecurity and Information Protection
Protection of controlled unclassified information (CUI)
System security requirements
Counterfeit Parts Prevention
Requirements for sourcing and traceability
Specialty Metals Compliance
Restrictions on sourcing materials
Commercial Item Flowdowns
Standard subcontract clause frameworks
Equal Opportunity and Labor Requirements
Employment and compliance provisions
Common Challenges Suppliers Face
Many suppliers struggle with:
Determining which clauses apply
Not all clauses flow down in full—some apply only in part.
Interpreting clause language
Regulatory text is often written for prime contracts, not suppliers.
Integrating clauses into their own contracts
Suppliers must often:
update PO terms
revise supplier agreements
ensure downstream flowdown
What a Strong Flowdown Framework Includes
A practical subcontracting or PO framework typically includes:
Incorporated clause structure
Clear reference to applicable FAR/DFARS provisions
Flowdown obligations
Requirements to pass clauses to lower-tier suppliers
Compliance alignment
Integration with:
quality systems (AS9100)
export controls (ITAR/EAR)
cybersecurity requirements
Standardized language
Consistent clause formatting across all contracts
How Suppliers Typically Handle Flowdowns
Most companies take one of three approaches:
1. Manual / ad hoc
Review each contract individually
time-consuming and inconsistent
2. Legal-heavy approach
3. Standardized system (most effective)
Use pre-built templates and clause libraries
fast, consistent, scalable
A Practical Approach
To simplify this process, many suppliers implement:
standardized purchase order terms
pre-built FAR/DFARS flowdown clauses
consistent subcontract templates
This allows procurement teams to:
reduce risk
save time
ensure consistency across contracts

Conclusion
FAR/DFARS flowdowns are a core part of doing business in the aerospace and defense industry.
While the requirements can be complex, a structured and standardized approach can significantly reduce risk and improve efficiency.
