FAR 46.4—Subpart 46.4

General.

FAR 46.401 explains where, when, and how the Government performs contract quality assurance and inspection. It covers the timing and location of quality assurance activities, including at any stage of manufacture or service performance and at subcontractors’ plants; the need to prepare quality assurance surveillance plans with the statement of work; the requirement to identify in each contract the place or places where the Government reserves inspection rights; restrictions on changing source-inspection locations without contracting officer approval; how destination contracts are handled when inspection occurs before delivery; who may perform Government inspection; how inspection must be documented; and the optional use of inspection approval or disapproval stamps. In practice, this section is the foundation for planning surveillance, assigning inspection responsibility, and avoiding disputes over whether the Government properly inspected or accepted supplies or services. It also helps prevent redundant inspection, supports traceability, and protects against substitution, transit damage, and fraud. For contractors, it signals where Government oversight may occur and what records may be used to prove inspection and acceptance. For contracting officers and quality assurance personnel, it sets the basic framework for writing the contract, planning surveillance, and documenting inspection actions.

Government contract quality assurance at source.

FAR 46.402 explains when the Government should perform contract quality assurance, including inspection, at the contractor’s source rather than somewhere else. The section identifies the main situations that justify source inspection: when off-site inspection would require uneconomical disassembly or destructive testing, when shipping or delaying correction of defective supplies would cause significant loss, when special instruments, gauges, or facilities exist only at the source, when off-site inspection would damage or require replacement of costly special packing or packaging, when Government inspection during performance is essential, and when source inspection is otherwise in the Government’s interest. In practice, this provision gives contracting personnel a basis for deciding where quality assurance should occur so the Government can verify compliance efficiently and avoid avoidable cost, damage, delay, or risk. It is a planning and oversight rule, not a contractor performance standard by itself, but it directly affects how inspection is organized, where acceptance-related checks occur, and how much access the Government needs during production or service performance. For contractors, it means some contracts will require more on-site Government presence and more coordination around production schedules, test points, and access to facilities and equipment.

Government contract quality assurance at destination.

FAR 46.403 explains when Government contract quality assurance (GCQA) is performed at the place where the supplies or services are delivered rather than at the contractor’s plant or another source location. It focuses on destination inspection and limits that form of QA mainly to inspection of the supplies or services, with specific situations where destination inspection is appropriate: off-the-shelf supplies needing no technical inspection, cases where testing equipment exists only at destination, perishable subsistence supplies, brand name products for authorized resale through commissaries or similar facilities, products processed under direct control of NIH or FDA, services performed at destination, and other situations where the Government’s interest justifies destination inspection. The section also addresses overseas shipments from the United States and states that overseas inspection is generally not required except in unusual circumstances, and only when the contracting officer has заранее determined that inspection can be performed or has arranged for it. In practice, this provision helps contracting officers decide where quality assurance should occur, reduces unnecessary inspection costs and delays, and ensures inspection is placed where it is most practical and effective. For contractors, it signals when acceptance may depend on delivery-site inspection and when shipment, receipt, and condition documentation may be especially important.

Government contract quality assurance for acquisitions at or below the simplified acquisition threshold.

FAR 46.404 explains how much Government contract quality assurance (GCQA) is appropriate for acquisitions at or below the simplified acquisition threshold (SAT). It tells the contracting officer to weigh three factors when deciding the level of oversight: the criticality of the supplies or services, the amount of possible loss if defects are not caught, and how likely it is that defective work can be replaced without dispute. When the conditions in FAR 46.202-2(b) apply, the default approach is limited Government inspection at destination, focused on basic acceptance checks such as type and kind, quantity, damage, operability when it can be readily determined, and preservation/packaging/packing/marking when relevant. The section also recognizes that some purchases need more scrutiny, including special situations and items with critical applications, and it allows use of standard inspection or higher-level quality requirements when warranted. Finally, it permits narrowing detailed inspection to the characteristics most likely to cause harm and reducing inspection frequency for repetitive purchases from a manufacturer with a strong defect-free history. In practice, this section is about matching oversight to risk so the Government does not over-inspect low-risk buys, but still protects itself when the item or service could cause significant harm or loss.

Subcontracts.

FAR 46.405 explains when the Government may perform quality assurance at the subcontract level and how that oversight must be handled. It covers four main topics: the limited purpose of Government quality assurance on subcontracted supplies or services, the specific situations that justify inspection or surveillance at a subcontractor’s plant, the rule against duplicating inspection when acceptable quality evidence already exists at the prime contractor’s plant, and the required wording of oral and written statements so Government actions do not alter contract relationships or waive acceptance rights. In practice, this section is about targeted oversight, not routine involvement in subcontract administration. It recognizes that the prime contractor remains responsible for meeting contract requirements, even when work is performed by subcontractors. For contracting officers and quality assurance personnel, the section helps determine when access to a subcontractor facility is appropriate and how to avoid overstepping into the prime-subcontract relationship. For contractors, it signals that subcontracted work may be subject to Government review in limited circumstances, but that the prime still carries the contractual burden for conformity.

Foreign governments.

FAR 46.406 addresses government contract quality assurance (GCQA) when the work is being performed for foreign governments or international agencies. It establishes that any such support must be administered in a way that aligns with U.S. foreign policy and national security objectives, rather than being treated as routine domestic quality assurance support. The section also limits when the U.S. Government may provide this assistance: only when it is consistent with, or specifically required by, applicable legislation, executive orders, or agency policies governing mutual international programs. In practice, this means contracting officers and quality assurance personnel must check not only the contract requirements, but also the broader legal and policy basis for supporting a foreign or international customer. The section is short, but it is important because it makes clear that GCQA for foreign entities is a policy-sensitive activity that may be restricted, conditioned, or prohibited depending on the governing authorities. It helps ensure that quality assurance support does not conflict with diplomatic, security, export-control, or international cooperation objectives of the United States.

Nonconforming supplies or services.

FAR 46.407 explains how the Government should handle supplies or services that do not conform to contract requirements, including when to reject them, when to allow correction or replacement, when acceptance or conditional acceptance may still be in the Government’s interest, and how to document and price any resulting adjustment. It covers the distinction between minor, major, and critical nonconformances; the role of the contracting officer, contract administration office, technical activity, and health officials in deciding whether to accept; and the need to discourage repeated delivery of defective work. The section also addresses equitable price reductions, withholding amounts for conditional acceptance, and when a contract modification is not necessary for minor defects. In addition, it requires prompt rejection notices, specifies when those notices must be in writing, and warns that delay can create implied acceptance. Finally, it includes special handling for counterfeit or suspect counterfeit items, requiring disposition instructions consistent with agency policy and possible retention for investigative or evidentiary purposes. In practice, this section is the Government’s roadmap for balancing quality enforcement with mission needs, while protecting the Government’s rights, documenting decisions, and ensuring any acceptance of defective work is supported by the record and properly priced.

Single-agency assignments of Government contract quality assurance.

FAR 46.408 assigns government-wide responsibility for quality assurance support for certain commodity acquisitions to specific civilian agencies with subject-matter expertise. It covers three product categories: drugs, biologics, and other medical supplies; food other than seafood; and seafood. For each category, the rule identifies the cognizant federal office responsible for providing quality assurance support: the Food and Drug Administration for drugs, biologics, and other medical supplies; the Department of Agriculture for food except seafood; and the National Marine Fisheries Service of the Department of Commerce for seafood. The section also tells agencies that need this support to request it directly from the cognizant office rather than routing the request through another channel. In practice, this provision helps ensure that inspections, surveillance, and other quality assurance activities are performed by the agency with the most relevant technical expertise and statutory responsibility, reducing duplication and improving product safety and compliance.
