Flow-Down Clause (FDC)

A contract clause that a prime contractor is required to include in its subcontracts. It passes certain legal, compliance, or performance obligations from the prime contract down to subcontractors.

What Is a Flow-Down Clause?

In government contracting, a Flow-Down Clause ensures that important contract requirements continue beyond the prime contractor and apply to lower-tier subcontractors when necessary.

These clauses are important because the government often requires specific rules to remain in effect throughout the full contract chain.

How It Works in Government Contracting

A Flow-Down Clause is usually addressed during subcontract formation and administration. The prime contractor reviews the prime contract and determines which clauses must be included in each subcontract.

It is used by prime contractors, subcontract managers, contracts teams, legal teams, and subcontractors. The prime contractor is responsible for making sure required clauses are properly flowed down when applicable.

In practice, flow-down clauses may cover areas such as cybersecurity, labor standards, small business requirements, audit rights, intellectual property, or compliance obligations.

Regulatory Framework

Flow-Down Clauses are part of the broader federal contract and subcontract compliance framework. Some clauses must be flowed down exactly as written, while others apply only in certain situations, such as based on subcontract value, type of work, or subcontractor role.

The exact flow-down requirement depends on the specific clause in the prime contract.

Why It Matters for Contractors

Flow-Down Clauses matter because failing to include required clauses in a subcontract can create compliance problems for the prime contractor. It may also expose both the prime and subcontractor to contract risk.

They also matter strategically because subcontractors need to understand which prime contract obligations apply to them before accepting the work.

Common Misconceptions About Flow-Down Clauses

Every prime contract clause must be flowed down.

Only certain clauses must be included in subcontracts, depending on the clause and subcontract situation.

Flow-down clauses only matter to large prime contractors.

They matter to both primes and subcontractors at many levels.

A subcontractor is only bound by the subcontract statement of work.

Required flow-down clauses may also impose compliance and legal obligations.
