Most federal subcontracts carry far more clauses than the regulation requires, and on Defense work that overreach is itself a violation. FAR 52.244-6, Subcontracts for Commercial Products and Commercial Services, carries an October 2025 clause date and is current under Federal Acquisition Circular 2026-01, effective March 13, 2026. It enumerates the clauses a prime must pass to its commercial subcontractors. A companion DoD clause, DFARS 252.244-7000, runs the other direction and bars primes from flowing down anything outside that list. Together they set the floor and ceiling of what a subcontract may impose.

Background

Commercial acquisition under FAR Part 12 exists so that companies selling to the government need not rebuild their operations around federal contract terms, and the flowdown architecture follows that logic. Two clauses do the work. FAR 52.212-5 goes into the prime contract when the government buys commercial products or services; its paragraph (e)(1) lists what the prime must push down the chain. FAR 52.244-6 goes into the prime's own commercial subcontracts, and its (c)(1) carries the parallel list at that tier.

The two lists are not identical. The prime-level list at 52.212-5(e)(1) runs to 27 clauses; the subcontract-level list at 52.244-6(c)(1) runs to 24. Both clauses are current under FAC 2026-01. A contractor reading only one will miss required terms or impose terms that do not belong.

Key Details

The mandatory set sorts into three practical groups.

Supply chain and information technology. The prohibitions that have expanded fastest in recent cycles: 52.204-21 Basic Safeguarding of Covered Contractor Information Systems, which excludes commercially available off-the-shelf items; 52.204-23, the Kaspersky Lab prohibition; 52.204-25, telecommunications and video surveillance equipment; 52.204-27, the ByteDance covered application prohibition; 52.204-30, FASCSA Orders—Prohibition, with Alternate I; and 52.240-1, barring unmanned aircraft systems from foreign entities covered by the American Security Drone Act.

Ethics and disclosure. 52.203-13, Contractor Code of Business Ethics and Conduct, flows down when the subcontract exceeds the threshold at FAR 3.1004(a) and performance runs more than 120 days. 52.203-15 applies only to Recovery Act funds. 52.203-17, Contractor Employee Whistleblower Rights, carries a carve-out: it does not reach DoD, NASA, the Coast Guard or the intelligence community. 52.203-19 bars certain internal confidentiality agreements.

Labor and socioeconomic. This is the longest group: 52.219-8, Utilization of Small Business Concerns; 52.222-21, Prohibition of Segregated Facilities; 52.222-26, Equal Opportunity; 52.222-35, Equal Opportunity for Veterans; 52.222-36, Equal Opportunity for Workers with Disabilities; 52.222-37, Employment Reports on Veterans; 52.222-40, National Labor Relations Act notification; 52.222-50, Combating Trafficking in Persons, with Alternate I; 52.222-55, EO 14026 minimum wages; 52.222-62, EO 13706 paid sick leave; 52.224-3, Privacy Training, with Alternate I; 52.225-26, Private Security Functions Outside the United States; 52.232-40, Accelerated Payments to Small Business Subcontractors; and 52.247-64, Preference for Privately Owned U.S.-Flag Commercial Vessels.

The 52.219-8 entry is widely misread. It flows down wherever further subcontracting opportunities exist, with no dollar trigger. The threshold at FAR 19.702(a) does separate work: where a subcontract other than one to a small business exceeds it, the subcontractor must itself adopt a subcontracting plan and carry the clause to lower tiers.

The prime-level list at 52.212-5(e)(1) adds the Service Contract Labor Standards clauses 52.222-41, 52.222-51 and 52.222-53, plus 52.222-54, Employment Eligibility Verification, and 52.226-6, Promoting Excess Food Donation to Nonprofit Organizations. But it omits two that 52.244-6(c)(1) carries: 52.203-15 and 52.204-21. Neither list is a subset of the other, which is why templates built from one go wrong.

Not every entry is automatic. The regulation qualifies 52.204-21, 52.222-40, 52.222-55, 52.222-62, 52.224-3, 52.232-40 and 52.247-64, each flowing down only as the underlying clause requires, and conditions 52.203-13, 52.203-15, 52.203-17 and 52.219-8 on the criteria above. Reading the list as uniformly mandatory pushes obligations onto subcontractors not subject to them.

FAR 52.244-6(c)(2) is the counterweight, and the most frequently ignored sentence in the clause: "While not required, the Contractor may flow down to subcontracts for commercial products or commercial services a minimal number of additional clauses necessary to satisfy its contractual obligations." It permits. It does not require, and "minimal" is doing deliberate work.

The DoD Prohibition

On Defense contracts that space narrows to almost nothing. DFARS 252.244-7000 carries a November 2023 clause date and an acquisition.gov effective date of May 7, 2026. It states that the contractor "shall not include the terms of any [FAR] clause or [DFARS] clause in subcontracts for commercial products or commercial services at any tier under this contract, unless" specific conditions are met.

Those conditions are narrow. A DFARS clause may flow down only if the clause itself says so. A FAR clause may flow down only if listed at FAR 12.301(d), or specified in FAR 52.212-5(e)(1) or in what the DFARS text calls paragraph (b)(1) of FAR 52.244-6. That last cross-reference is stale: the enumerated list now sits at 52.244-6(c)(1), while (b) addresses incorporating commercial components. Everything else stays at the prime level.

The same clause, implementing 10 U.S.C. 3457(c), requires the contractor to treat as commercial products any items valued at less than $10,000 per item bought for use across multiple contracts with DoD and other parties and not identifiable to any particular contract when purchased. Those items must then meet the contract terms applicable to commercial products under 52.244-6.

What It Means for Contractors

For primes, the exposure runs both ways. Omitting a required flowdown leaves a gap in the government's chain of obligation. Dumping the entire prime clause set into a commercial subcontract is no conservative hedge on DoD work; it breaches 252.244-7000. Check each clause in your template against the current 52.244-6(c)(1) list, then the conditional qualifiers, then the DFARS test if the work is Defense-funded.

For subcontractors and small primes receiving flowdown packages, this is leverage. A prime that sends a forty-clause commercial subcontract on DoD work is asking you to accept terms it is prohibited from imposing. Cite the clause by number, ask which DFARS condition each disputed clause satisfies, and make the prime name the authority. Most clause dumping survives because nobody asks.

Track version dates too. Clause lists move with each Federal Acquisition Circular, so a template built on a 2024 set is now both over-inclusive and out of date. Rebuild it from the clause text on acquisition.gov, not from the last award you signed.

One boundary: flowdowns govern which clauses transfer down the chain, not the limitations on subcontracting, which govern how much work may be subcontracted.
