FAR 4.1701—Definitions.
Plain-English Summary
FAR 4.1701 provides the definitions used in this subpart, and it focuses on two specific terms: “FAIR Act agencies” and “first-tier subcontract.” These definitions matter because they determine which agencies are covered by the inventory-related requirements tied to the FAIR Act and which subcontract relationships count for reporting, tracking, or compliance purposes under this subpart. In practice, the section draws a line between true first-tier subcontracts—those awarded directly by the prime contractor to obtain supplies or services, including construction, for contract performance—and ordinary supplier arrangements that are part of a contractor’s general supply chain or indirect cost structure. That distinction is important because not every vendor relationship is treated as a subcontract for purposes of this subpart. Contractors and contracting personnel must therefore identify the correct agency coverage and correctly classify downstream purchasing arrangements to avoid overreporting, underreporting, or applying the wrong compliance standard.
Key Rules
FAIR Act agency coverage
“FAIR Act agencies” are the agencies that the FAIR Act requires to submit annual inventories of activities performed by Government personnel. The term is used to identify which agencies are subject to the inventory-related framework in this subpart.
First-tier subcontract defined
A “first-tier subcontract” is a subcontract awarded directly by the prime contractor to acquire supplies or services, including construction, for performance of the prime contract. The key feature is direct award by the contractor to support contract performance.
Supplier agreements excluded
The definition expressly excludes contractor supplier agreements with vendors, such as long-term material or supply arrangements that support multiple contracts. If the costs are normally charged to general and administrative expenses or other indirect costs, the arrangement is not treated as a first-tier subcontract.
Substance over label
Whether an arrangement is a first-tier subcontract depends on its function and cost treatment, not just how the parties label it. A vendor relationship that looks like a standing supply arrangement may fall outside the definition even if it is important to performance.
Responsibilities
Agency
Determine whether it is a FAIR Act agency subject to the annual inventory requirements referenced by this subpart and apply the subpart only where the definition is met.
Contracting Officer
Use the definitions in this subpart when applying related FAR requirements, and ensure that agency coverage and subcontract classifications are understood consistently in contract administration and reporting.
Prime Contractor
Identify which downstream awards are first-tier subcontracts and distinguish them from supplier agreements or indirect-cost vendor arrangements when complying with any requirements that depend on this definition.
Subcontract Administrator / Procurement Staff
Classify vendor and subcontract relationships correctly, maintain records supporting the classification, and avoid treating indirect supply arrangements as first-tier subcontracts.
Practical Implications
This definition affects what gets counted, tracked, or reported under the subpart, so misclassification can create compliance errors.
A common pitfall is calling every vendor purchase a subcontract; long-term supply agreements and indirect-cost arrangements are specifically excluded.
Contractors should look at both the purpose of the purchase and how the cost is normally treated in accounting, not just the contract title.
Contracting officers should confirm that the parties are using the same definition when discussing subcontract reporting or related compliance obligations.
Because the term is limited to subpart use, readers should apply it only where this FAR subpart specifically relies on these definitions.
Official Regulatory Text
As used in this subpart– FAIR Act agencies means the agencies required under the FAIR Act to submit inventories annually of the activities performed by Government personnel. First-tier subcontract means a subcontract awarded directly by the contractor for the purpose of acquiring supplies or services (including construction) for performance of a prime contract. It does not include the contractor’s supplier agreements with vendors, such as long-term arrangements for materials or supplies that benefit multiple contracts and/or the costs of which are normally applied to a contractor’s general and administrative expenses or indirect costs.
