FAR 52.246—[Reserved]

Contractor Inspection Requirements.

FAR 52.246-1, Contractor Inspection Requirements, allocates primary responsibility for inspection and testing to the contractor. It covers the contractor’s duty to perform or arrange all inspections and tests needed to prove that supplies or services meet contract requirements, including any applicable technical requirements for specified manufacturers’ parts. The clause also addresses how contractor inspection interacts with Government inspection and testing requirements in the contract specifications, making clear that contractor inspection generally takes precedence. The main exception is for specialized inspections or tests that the contract specifically says must be performed solely by the Government. In practice, this clause is important because it places the burden on the contractor to build quality assurance into performance, document compliance, and avoid assuming that Government review will substitute for the contractor’s own inspection program.

Inspection of Supplies-Fixed-Price.

FAR 52.246-2, Inspection of Supplies—Fixed-Price, sets the basic inspection and acceptance framework for fixed-price supply contracts. It covers the contractor’s duty to maintain an acceptable inspection system, prepare and retain inspection records, and tender only conforming supplies; the Government’s right to inspect and test supplies at any place and time practicable before acceptance; the contractor’s duty to provide facilities and assistance for on-site Government inspection; allocation of inspection and reinspection costs; the Government’s right to reject or require correction of nonconforming supplies; removal, correction, replacement, and equitable price reduction procedures; advance notice requirements when Government quality assurance at source applies; prompt Government acceptance or rejection after delivery; and the effect of inspection and acceptance, including the limited circumstances in which acceptance is not conclusive. In practice, this clause is the core risk-allocation provision for supply quality in fixed-price contracting: it tells the contractor that inspection by the Government does not shift responsibility for defects, and it tells the Government how to preserve its rights while avoiding undue delay to performance. It also establishes remedies if supplies are late for inspection, fail reinspection, or remain nonconforming after delivery. For contractors, the clause drives quality control, documentation, and corrective-action discipline; for contracting officers, it provides the authority to inspect, reject, require correction, assess added inspection costs, and pursue default or price reduction when necessary.

Inspection of Supplies-Cost-Reimbursement.

FAR 52.246-3, Inspection of Supplies—Cost-Reimbursement, sets the inspection, acceptance, and correction framework for cost-reimbursement contracts that involve supplies or services furnishing supplies. It covers the required definitions of contractor’s managerial personnel and supplies, the contractor’s duty to maintain an acceptable inspection system and records, the Government’s right to inspect and test supplies and contractor/subcontractor facilities, the contractor’s duty to provide facilities and assistance for on-site inspection, acceptance timing and deemed acceptance, the Government’s right to require correction or replacement of nonconforming supplies after acceptance, the contractor’s obligation to disclose prior correction/replacement when retendering supplies, remedies if the contractor does not act promptly, special no-cost correction rules for fraud, lack of good faith, willful misconduct, or certain employee conduct, the treatment of corrected or replacement supplies, the contractor’s limited liability for pre-delivery nonconformance, and the separate treatment of Government-furnished property. In practice, this clause allocates quality-control and inspection responsibilities while preserving the Government’s ability to verify compliance and obtain correction of defective supplies. Because it is used in cost-reimbursement contracting, it also ties correction costs to allowable cost principles and generally does not add fee for corrective work, which matters directly to contractor pricing, accounting, and risk management. It is designed to prevent acceptance of defective supplies from becoming a shield against later correction when defects existed at delivery, while also limiting the contractor’s exposure unless the contract or the clause specifically provides otherwise. For contracting officers and contractors, the clause is a roadmap for inspection rights, recordkeeping, acceptance timing, post-acceptance remedies, and the consequences of nonconforming supplies.

Inspection of Services-Fixed-Price.

FAR 52.246-4, Inspection of Services—Fixed-Price, sets the Government’s quality assurance rights and the contractor’s quality control duties for fixed-price service contracts. It covers the definition of “services,” the contractor’s obligation to maintain an acceptable inspection system and records, the Government’s right to inspect and test services during performance, the contractor’s duty to provide facilities and assistance for inspections performed on contractor or subcontractor premises, and the remedies available when services do not conform to contract requirements. It also addresses what happens when defects can be corrected by reperformance versus when they cannot, including future corrective action, price reduction, Government performance at contractor expense, and termination for default. In practice, this clause is the core enforcement tool for service quality on fixed-price contracts: the contractor bears the risk of delivering conforming services, while the Government retains the right to verify performance and require correction without paying more for nonconforming work. It matters because service deficiencies can be harder to measure than product defects, so the clause gives the parties a clear framework for inspection, correction, and remedies. Contractors should treat this clause as a requirement to build and document a real quality control process, not just a paper procedure, and contracting officers should use it to support timely surveillance and enforceable corrective action.

Inspection of Services-Cost-Reimbursement.

FAR 52.246-5, Inspection of Services—Cost-Reimbursement, sets the quality-control and acceptance framework for cost-reimbursement service contracts. It covers the definition of "services," the contractor’s duty to maintain an acceptable inspection system and keep inspection records, the Government’s right to inspect and test services during performance, the Government’s remedies when services do not conform, and the consequences if the contractor does not promptly correct defects or prevent recurrence. In practice, this clause is important because cost-reimbursement contracts place more direct oversight on the Government while still requiring the contractor to manage quality and document compliance. The clause gives the Government flexibility to verify performance throughout the contract, but it also limits inspection to a manner that does not unduly delay the work. It matters to contractors because poor quality can lead to reperformance at no additional fee, fee reductions, or even default termination. It matters to contracting officers because it provides a structured set of remedies for nonconforming services without waiting until the end of performance.

Inspection-Time-and-Material and Labor-Hour.

FAR 52.246-6 is the inspection clause used in time-and-materials and labor-hour contracts. It covers the contractor’s duty to maintain an acceptable inspection system, keep inspection records, and provide access to those records; the Government’s right to inspect and test materials, services, plants, and subcontractor facilities; the contractor’s duty to provide facilities and assistance for inspection; rules for acceptance or rejection at the place of delivery and the 60-day deemed-acceptance rule; the Government’s post-acceptance right to require correction or replacement of nonconforming work; the contractor’s obligation to disclose prior corrections when resubmitting work; the Government’s remedies if the contractor does not promptly correct defects, including charging increased costs or terminating for default; the special no-cost correction rule for failures caused by fraud, lack of good faith, willful misconduct, or certain employee conduct tied to managerial negligence; the treatment of corrected or replacement items; the contractor’s limited liability for nonconforming work except as stated in the clause; and the rule that Government-furnished property is handled under the Government property clause unless the contract says otherwise. The clause also defines contractor’s managerial personnel and, when data is not covered by a warranty of data clause, treats data as “materials.” In practice, this clause is important because it allocates inspection and correction risk in a cost-reimbursement-like environment where labor and materials are billed differently than under fixed-price contracts. It gives the Government broad inspection and post-acceptance correction rights, but also limits those rights with timing rules, a 60-day presumption of acceptance, and a reduced labor rate for correction work by excluding profit. Alternate I changes the acceptance process when inspection and acceptance occur at the contractor’s plant and allows the Government to charge the contractor for extra inspection costs when items are not ready when requested. Contractors should use this clause to build strong quality control, document inspections and corrective actions, and manage readiness for Government inspection; contracting officers should use it to ensure inspection rights, acceptance procedures, and correction remedies are clearly administered.

Inspection of Research and Development-Fixed-Price.

FAR 52.246-7, Inspection of Research and Development—Fixed-Price, sets the quality assurance and acceptance framework for fixed-price R&D contracts. It covers the contractor’s duty to maintain an acceptable inspection system and keep inspection records; the Government’s right to inspect and test work, including at the contractor’s or subcontractor’s premises and before acceptance; the contractor’s duty to provide facilities and assistance for on-site Government inspections; the timing and effect of Government acceptance or rejection; the definition of nonconforming work; the Government’s right to reject or accept nonconforming work with an equitable price reduction; and the limits of inspection and acceptance, including latent defects, fraud, gross mistakes amounting to fraud, and other contract-specific exceptions. It also addresses remedies when work is defective, including correction or replacement at no increase in price, price reduction, or repayment, and allocates transportation costs when work is returned. In practice, this clause is important because it preserves Government oversight without shifting day-to-day quality control away from the contractor, while also making clear that inspection does not equal acceptance and acceptance is usually final only after the work meets contract requirements. For contractors, the clause drives documentation, internal controls, and readiness for Government review; for contracting officers, it provides the tools to inspect, reject, negotiate price reductions, and enforce remedies when R&D work does not conform.

Inspection of Research and Development-Cost-Reimbursement.

FAR 52.246-8, Inspection of Research and Development—Cost-Reimbursement, sets the inspection and acceptance framework for cost-reimbursement R&D contracts where the main deliverable is an end item rather than designs, drawings, or reports. It covers the clause’s applicability, key definitions such as “Contractor’s managerial personnel” and “work,” the contractor’s duty to maintain an acceptable inspection system and records, the Government’s right to inspect and test work and facilities, the contractor’s duty to support Government inspections, acceptance timing and deemed acceptance after 90 days, post-acceptance correction or replacement rights and time limits, the Government’s remedies if the contractor does not act promptly, special Government rights in cases of fraud, lack of good faith, or willful misconduct, the treatment of corrected or replacement items, the contractor’s limited liability for nonconforming items at delivery, and the handling of Government-furnished property. In practice, this clause is important because it balances the Government’s need to verify technical performance in R&D work with the realities of cost-reimbursement contracting, where work may be iterative and acceptance may occur before all issues are fully known. It also creates a structured process for post-acceptance fixes, including who pays, when the Government can demand corrections at no cost, and when disputes arise. For contractors, the clause drives quality control, documentation, and disclosure obligations; for contracting officers, it provides a tool to manage technical risk, acceptance, and remedies without turning every defect into a default issue. The clause is used only when the primary objective is delivery of end items other than designs, drawings, or reports and a cost-reimbursement contract is contemplated, unless another inspection clause is more appropriate or use is impractical.

Inspection of Research and Development (Short Form).

FAR 52.246-9, Inspection of Research and Development (Short Form), gives the Government a broad right to inspect and evaluate both the work being performed and the premises where that work is performed under a research and development contract. It also addresses how that inspection must be conducted: at all reasonable times and in a way that does not unduly delay the contractor’s work. The clause further covers what happens when the Government conducts inspection or evaluation on the contractor’s or a subcontractor’s premises, requiring the contractor to provide, and to flow down to subcontractors the duty to provide, reasonable facilities and assistance for safe and convenient performance of the Government’s duties. In practice, this clause is about access, cooperation, and minimizing disruption while preserving the Government’s ability to monitor technical progress, compliance, and performance in R&D efforts. It is a short clause, but it is important because R&D work often involves evolving methods, specialized facilities, and subcontracted research activities that the Government may need to observe directly.

[Reserved]

Higher-Level Contract Quality Requirement.

FAR 52.246-11, Higher-Level Contract Quality Requirement, tells contractors that they must comply with the specific higher-level quality standard(s) identified by the contracting officer in the contract, and it explains how those standards must be carried down into certain subcontracts. This clause is used when the Government wants more than the contractor’s basic quality system and needs a named external standard—such as an industry, military, or agency quality standard—to govern performance. The clause covers four main topics: incorporation of the identified higher-level quality standard(s), the contracting officer’s role in listing the exact standard and any tailoring, the contractor’s duty to flow the applicable requirements down to lower-tier subcontracts, and the types of subcontracts where that flowdown is required. In practice, the clause is meant to ensure that critical or technically demanding work is performed under a disciplined quality framework, especially where design control, in-process controls, testing, inspection, documentation, or metrology are important. It also helps the Government avoid quality gaps by making sure subcontractors working on sensitive or complex items are held to the same higher-level requirements. For contractors, the clause creates a compliance obligation that affects contract administration, subcontract drafting, supplier management, and quality assurance planning.

Inspection of Construction.

FAR 52.246-12, Inspection of Construction, sets the inspection and quality-control framework for construction contracts. It covers the definition of “work,” the contractor’s duty to maintain an adequate inspection system and records, the Government’s right to inspect and test before acceptance, and the limits of those inspections. It also explains that Government inspection does not relieve the contractor of responsibility for quality, loss, or contract compliance, and that inspectors cannot change contract terms without written contracting officer authorization. The clause addresses contractor support for inspections and tests, including furnishing facilities, labor, and materials, and it allows the Government to charge the contractor for extra inspection costs caused by the contractor’s failure to have work ready or by the need for reinspection or retesting. It further covers correction or replacement of nonconforming work, Government remedies if the contractor does not promptly correct defects, the special rule for uncovering or tearing out completed work for examination, equitable adjustments when the work proves compliant, and final acceptance of completed work. In practice, this clause is central to construction contract administration because it defines how quality is checked, who bears the cost of defects, when the Government may require rework, and when acceptance becomes final except for limited post-acceptance rights such as latent defects, fraud, gross mistakes amounting to fraud, and warranty or guarantee claims.

Inspection-Dismantling, Demolition, or Removal of Improvements.

FAR 52.246-13 sets the inspection and quality-control framework for contracts involving dismantling, demolition, or removal of improvements. It covers Government inspection rights, the contractor’s duty to provide access and support for inspection, the Government’s obligation not to unreasonably delay the work, the contractor’s responsibility for defective workmanship and resulting property damage, the duty to remove and replace unsatisfactory facilities, materials, and equipment, and the Government’s remedies if the contractor does not promptly correct problems. It also addresses the Government’s ability to obtain corrective work by other means and charge the cost to the contractor, as well as the possibility of termination for default. In practical terms, this clause gives the Government strong oversight over hazardous or irreversible work while placing primary responsibility on the contractor to perform safely, competently, and without delay. It is especially important because demolition and dismantling work can create immediate safety risks, hidden structural issues, and costly damage if workmanship is poor. The clause also makes clear that the contractor and any surety may be financially liable for repair or replacement costs to the extent stated in the contract.

Inspection of Transportation.

FAR 52.246-14, Inspection of Transportation, is a clause used in certain transportation-service contracts to give the Government a formal right to inspect and test the contractor’s transportation services, facilities, and equipment. The clause applies to freight transportation services, including local drayage, by rail, motor (including bus), domestic freight forwarder, and domestic water carriers (including inland, coastwise, and intercoastal). It specifically excludes use for domestic or international air carriers, international ocean carriers, freight services provided under bills of lading, and transportation negotiated at reduced rates under 49 U.S.C. 10721 or 13712. In practice, the clause is about oversight and quality assurance in transportation contracting: it lets the Government verify that the carrier’s operations, equipment, and service performance meet contract requirements. It also requires the contractor to provide free access, reasonable facilities, and assistance so Government representatives can carry out inspections and tests. For contracting officers, the key issue is knowing when the clause is prescribed and when it is prohibited; for contractors, the key issue is understanding that Government inspection rights extend beyond paperwork to operational access.

Certificate of Conformance.

FAR 52.246-15, Certificate of Conformance, explains when a contractor may use a signed certificate in place of source inspection for supplies, and how that certificate must be handled in the shipment and payment process. It applies only when the clause is prescribed and when the conditions in FAR 46.504 are met, and it depends on written authorization from the cognizant Contract Administration Office (CAO). The clause preserves the Government’s inspection rights, so a certificate does not waive the Government’s ability to inspect, reject, or require correction of defective supplies or services. It also sets out the required placement of the certificate with inspection or receiving reports, including special handling when Defense Contract Administration Services performs contract administration. Finally, it provides the exact certification language the contractor must use, including statements about contract compliance, quality, quantity, packaging, marking, identification, and shipment details, and it states the Government’s right to reject defective items within a reasonable time after delivery.

Responsibility for Supplies.

FAR 52.246-16, Responsibility for Supplies, allocates title and risk of loss for supplies under a federal contract. It explains when title passes to the Government, when the contractor remains responsible for loss or damage, and how those rules change depending on whether transportation is FOB origin or FOB destination. The clause also addresses nonconforming supplies that are subject to rejection, making clear that the contractor keeps the risk until the defect is cured or the Government accepts the items. In addition, it limits contractor liability for loss or damage caused by the negligence of Government personnel acting within the scope of their employment. In practice, this clause matters because it determines who bears the financial consequences if supplies are lost, damaged, or mishandled during shipment, inspection, or delivery, and it helps avoid disputes over ownership and responsibility when something goes wrong.

Warranty of Supplies of a Noncomplex Nature.

FAR 52.246-17 establishes a warranty regime for supplies of a noncomplex nature, meaning relatively straightforward items where defects and nonconformance can be identified and corrected without the more elaborate warranty structures used for complex systems. The clause covers the definition of key terms such as acceptance and supplies, the contractor’s express warranty that delivered supplies will be free from defects in material and workmanship and will conform to contract requirements, and the contractor’s separate warranty that preservation, packaging, packing, marking, and shipment preparation will also comply with the contract. It also addresses who pays transportation costs when supplies must be returned, corrected, or replaced; how warranty coverage applies to corrected or replacement items; and the exclusion of implied warranties of merchantability and fitness for a particular purpose. On the Government side, the clause sets the time limit for giving written notice of breach, the remedies available after notice, and special procedures when inspection is performed by sampling, including grouping supplies, projecting sample results, screening, returning supplies, and requiring equitable adjustments. It further gives the Government a self-help remedy to correct or replace nonconforming supplies from another source and charge the contractor when the contractor fails to act timely or endangers delivery performance. In practice, this clause matters because it shifts post-acceptance risk back to the contractor for a defined period, gives the Government a clear path to enforce quality obligations, and requires both parties to track delivery, notice, and corrective-action deadlines carefully.

Warranty of Supplies of a Complex Nature.

FAR 52.246-18, Warranty of Supplies of a Complex Nature, sets out a specialized warranty framework for complex end items and related services when the Government needs stronger post-delivery protection than a simple inspection-and-acceptance regime. The clause defines key terms such as acceptance and supplies, establishes the contractor’s core warranty that delivered supplies will be free from defects in material and workmanship and will conform to contract requirements, and limits the warranty for Government-furnished property to proper installation unless the contractor modifies that property. It also addresses replacement or corrected items, the effect of Government-caused unavailability of facilities, tooling, drawings, or other equipment, the contractor’s duty to provide data and reports related to corrections, transportation costs for returned items, and the exclusion of implied warranties of merchantability and fitness for a particular purpose. On the Government side, the clause describes available remedies for breach, including repair, replacement, furnishing of materials and installation instructions, or an equitable price reduction. It further requires the Contracting Officer to specify notice periods, contractor response times, and the period for exercising warranty remedies, and it preserves the Government’s other contractual rights and remedies. In practice, this clause is important because it allocates post-delivery risk, sets clear timelines for defect notice and corrective action, and gives the Government a structured way to obtain repair or replacement without increasing contract price when complex supplies fail to meet requirements.

Warranty of Systems and Equipment under Performance Specifications or Design Criteria.

FAR 52.246-19, Warranty of Systems and Equipment under Performance Specifications or Design Criteria, sets out a government warranty regime for systems and equipment when the contract is based on performance specifications or design criteria rather than detailed contractor design responsibility. The clause defines key terms such as acceptance, defect, and supplies, then establishes the contractor’s warranty obligations, including the period of coverage, the duty to correct defects discovered before acceptance, and the process for government notice of defects discovered after acceptance. It also covers the contractor’s obligation to recommend corrective action, comply with government-directed corrections at no increase in price, provide related data and reports, and propose a contract amendment and equitable price reduction when the government elects not to require full correction. The clause further addresses the warranty treatment of corrected or replacement items, limits responsibility for defects in government-furnished property, allocates transportation and transit risk when items are returned for correction, and excludes implied warranties of merchantability and fitness for a particular purpose. Finally, it preserves the government’s remedies by stating that this warranty is not limited by inspection and acceptance language and is cumulative with other contract rights. In practice, this clause is important because it gives the government a structured post-acceptance remedy for defects in systems and equipment while also giving the contractor a defined process, notice framework, and limits on liability.

Warranty of Services.

FAR 52.246-20, Warranty of Services, sets out the Government’s post-acceptance remedy when contracted services are defective or do not conform to contract requirements. It defines “acceptance” for purposes of the clause, establishes the contractor’s warranty that services will be free from defects in workmanship and conform to the contract at the time of acceptance, and requires the contracting officer to specify a notice period for identifying defects or nonconformance. The clause also explains the Government’s options after notice: require the contractor to correct or reperform the services, or decide that correction is unnecessary. If correction or reperformance is required, it must be at no cost to the Government, and any corrected or reperformed services remain covered by the same warranty. If the contractor does not comply, the Government may obtain replacement services and charge the contractor, or seek an equitable adjustment in price. If the Government chooses not to require correction or reperformance, the contracting officer must make an equitable adjustment in the contract price. In practice, this clause is important because it preserves a remedy after acceptance, allocates risk for defective service performance, and gives both parties a clear process for handling service deficiencies discovered after the Government has accepted the work.

Warranty of Construction.

FAR 52.246-21, Warranty of Construction, sets out the Government’s standard warranty for fixed-price construction contracts when an agency has approved use of a warranty clause. It covers the contractor’s promise that the work will conform to contract requirements and be free from defects in equipment, material, design, and workmanship; the warranty period and when it starts; the contractor’s duty to correct defects and related damage; the Government’s notice and self-help rights if the contractor does not act; the contractor’s obligations to obtain, execute, and enforce subcontractor, manufacturer, and supplier warranties; the Government’s right to sue on those warranties after the contractor’s warranty expires; the limitation for Government-furnished material or design; the preservation of the Government’s rights for latent defects, gross mistakes, or fraud; and the special Alternate I rule for brand-name-and-model equipment specified by the Government. In practice, this clause allocates post-acceptance risk on construction work, gives the Government a clear remedy for defective performance, and requires contractors to manage warranty flowdown and enforcement through their supply chain. It is especially important because it operates after acceptance, when ordinary inspection rights may be limited, and because it can shift significant repair and replacement costs back to the contractor if defects appear within the warranty period.

[Reserved]

Limitation of Liability.

FAR 52.246-23, Limitation of Liability, allocates risk for government property damage caused by defective or deficient supplies after the Government has accepted those supplies. The clause generally protects the contractor from liability for loss of or damage to Government property other than the delivered supplies themselves, but only when the damage occurs after acceptance and results from defects or deficiencies in the supplies. It also creates two important exceptions: the limitation does not apply if the defect, deficiency, or Government acceptance resulted from willful misconduct or lack of good faith by the contractor’s managerial personnel, and the contractor remains liable up to the amount of any applicable insurance or self-insurance reserve covering this type of loss. In practice, this clause matters because it defines when the Government can recover for post-acceptance property damage, how far that recovery can go, and when contractor management conduct can remove the liability shield entirely. It also requires careful attention to the contractor’s insurance program and any self-insurance reserves, since those amounts can become the ceiling on liability even where the general limitation would otherwise apply. The clause is a risk-allocation provision, not a warranty clause, and it works alongside any other remedies expressly provided elsewhere in the contract.

Limitation of Liability-High-Value Items.

FAR 52.246-24, Limitation of Liability-High-Value Items, allocates post-acceptance risk for certain high-value supplies and limits when the contractor is financially responsible for loss of or damage to Government property caused by defects or deficiencies in those supplies. The clause addresses the basic liability rule after Government acceptance, the exception for willful misconduct or lack of good faith by the contractor’s managerial personnel, the effect of contractor insurance or self-insurance reserves, the contractor’s continuing obligations for correction, repair, replacement, or other relief, the Government’s right to recover the cost of correction when repair or replacement is not feasible or desired, and the clause’s relationship to other contract clauses such as warranty of technical data, ground/flight risks, and Government property. It also includes Alternate I, which is used when the contract contains both high-value items and other end items and requires the contracting officer to identify the covered items by line item. In practice, this clause narrows the contractor’s exposure after acceptance, but it does not eliminate all liability, especially where managerial misconduct, insurance coverage, or separate contractual remedies apply. It is designed to balance the Government’s need for protection on expensive items with a predictable liability framework for contractors.

Limitation of Liability-Services.

FAR 52.246-25, Limitation of Liability-Services, allocates risk for post-acceptance property damage caused by defective or deficient services and related materials. It applies when the Government has accepted the services, but later suffers loss of or damage to Government property because the services or furnished materials were defective or deficient. The clause generally limits the contractor’s liability after acceptance, but it creates important exceptions for willful misconduct or lack of good faith by the contractor’s managerial personnel and for situations where the contractor has insurance or a self-insurance reserve covering the loss. It also defines who counts as “contractor’s managerial personnel,” which is critical because misconduct by those individuals can remove the liability limitation. In practice, this clause is a risk-allocation tool: it protects contractors from open-ended liability after the Government accepts services, while preserving Government recovery rights in cases of serious misconduct or available insurance coverage. Contracting officers, contractors, and claims personnel should read it together with the contract’s acceptance provisions, any express responsibility clauses, and the contractor’s insurance arrangements.

Reporting Nonconforming Items.

FAR 52.246-26, Reporting Nonconforming Items, is a quality-control and supply-chain integrity clause aimed at preventing counterfeit, suspect counterfeit, and materially defective items from reaching the Government. It defines the key terms used in the clause, including common item, counterfeit item, suspect counterfeit item, critical item, critical nonconformance, major nonconformance, and design activity, so contractors and contracting officers can apply the reporting rules consistently. The clause requires contractors to screen GIDEP reports as part of their inspection or quality system, notify the contracting officer within 60 days when they suspect counterfeit items, retain suspect items pending disposition, and report certain counterfeit or nonconforming items to GIDEP within 60 days. It also explains when GIDEP reporting is not required, including for certain foreign contractors, items under an ongoing criminal investigation, and some nonconforming items where the defect source has not released the item to more than one customer. The clause limits what may be included in GIDEP reports to protect trade secrets and other legally protected information, provides a DoD-specific civil liability protection for good-faith reporting of counterfeit electronic parts, and requires flowdown of the clause to certain subcontracts. In practice, this clause is a key tool for early detection, traceability, and information sharing across the defense and federal supply chain, and it places real compliance obligations on contractors to identify, hold, report, and flow down nonconformance information promptly and accurately.
