Nonconforming Product (NCR)

Full name: Nonconformance Report / Nonconforming Product
A nonconforming product, often documented as an NCR (nonconformance report), is any product, material or output that fails to meet a specified requirement, whether that requirement comes from a customer, a regulation, an internal specification or an applicable standard. The nonconforming product process covers identifying, segregating, evaluating and dispositioning nonconforming items, such as by rework, repair, use-as-is, return to supplier or scrap, so they are not unintentionally used or shipped.

What is Nonconforming Product (NCR)?

A nonconforming product is any output, whether raw material, in-process work or a finished product, that does not meet a defined requirement. The requirement can originate from a customer specification, a regulatory standard, an internal drawing or procedure, or the organization's own quality management system.

When a nonconformance is identified, it is typically documented on a nonconformance report, commonly abbreviated NCR, which records what was found, where it was found, its immediate disposition and, where warranted, the investigation into its cause.

Nonconforming product management focuses first on containment, ensuring the item is segregated or clearly identified so it cannot be mistakenly used, shipped or mixed with conforming product, and second on disposition, deciding what happens to the nonconforming item itself.

Why is Nonconforming Product (NCR) important?

A disciplined nonconforming product process prevents defective or noncompliant items from reaching customers, protecting both product safety and organizational reputation. Left unmanaged, nonconforming material can be inadvertently reworked, shipped or mixed back into inventory.

Tracking nonconformances also generates the data organizations need to identify patterns, whether by part number, supplier, shift or process step, that point toward a systemic issue worth escalating to a formal corrective action.

A well-run process improves cost visibility as well, since nonconformance records typically capture scrap, rework and disposition costs that feed into an organization's cost of poor quality metrics.

How does Nonconforming Product (NCR) work?

A typical nonconforming product process includes:

  1. Identification. Detect the nonconformance through inspection, testing, complaint or audit.
  2. Documentation. Record the item, requirement violated, quantity and discovery point on an NCR.
  3. Containment. Segregate or clearly tag the nonconforming item to prevent unintended use.
  4. Evaluation. Assess the significance, including whether similar items may be affected.
  5. Disposition. Decide whether to use-as-is, rework, repair, return to supplier or scrap the item, typically with defined approval authority.
  6. Escalation. Route recurring or high-risk nonconformances into the CAPA process for root cause investigation.
  7. Closure and trending. Close the NCR and periodically review nonconformance trends by type, source and cost.

Nonconforming Product (NCR) vs. CAPA

Comparison Nonconforming Product (NCR) CAPA
Purpose Document and disposition a specific nonconforming item Investigate root cause and prevent recurrence or occurrence
Scope A single item, lot or batch Often broader, addressing systemic or recurring issues
Typical output Use-as-is, rework, repair, return or scrap decision Root cause, corrective action and effectiveness verification
Relationship May trigger a CAPA if significant or recurring Often originates from one or more NCRs

Real-world examples of Nonconforming Product (NCR)

An incoming inspector at an electronics manufacturer finds a batch of components outside the specified tolerance. The lot is quarantined, an NCR is opened, and the material review board decides to return the lot to the supplier rather than sort and use conforming pieces.

A medical device assembler discovers a labeling discrepancy during final inspection. The affected units are segregated, an NCR documents the finding, and the disposition calls for relabeling under supervision before the units are released.

An automotive supplier notices a recurring dimensional nonconformance across several NCRs tied to the same fixture. The trend prompts a formal CAPA to investigate and correct the fixture rather than continuing to disposition individual parts one at a time.

Regulations and standards related to Nonconforming Product (NCR)

ISO 9001 requires organizations to identify and control outputs that do not conform to requirements to prevent their unintended use or delivery, and to take action based on the nature of the nonconformity and its effect on conformity of products and services. This requirement sits alongside Clause 10.2 on corrective action.

ISO 13485 and FDA 21 CFR Part 820 contain specific requirements for medical device manufacturers to control nonconforming product, including defined responsibility and authority for review and disposition. AS9100 and IATF 16949 add aerospace- and automotive-specific expectations, including material review board processes for disposition decisions.

Regulators and auditors commonly examine whether nonconforming product was properly contained before disposition, whether disposition decisions were made by authorized personnel, and whether recurring nonconformances were escalated appropriately.

Common mistakes with Nonconforming Product (NCR)

Common mistakes include failing to physically segregate or clearly tag nonconforming material, which risks it being mixed back into conforming inventory, and allowing disposition decisions to be made by personnel without proper authority.

Other problems include treating every nonconformance as an isolated event without reviewing trends, and closing NCRs without addressing whether similar product elsewhere may also be affected by the same underlying issue.

Frequently asked questions

An NCR documents a specific instance of nonconforming product and its disposition. A CAPA is the broader investigation and corrective action process used to address the root cause of a nonconformance, particularly when it is significant or recurring. An NCR may trigger a CAPA, but not every NCR requires one.
Common dispositions include use-as-is with appropriate approval, rework to bring the item into conformance, repair, return to supplier, or scrap. The appropriate disposition depends on the nature of the nonconformity and applicable requirements.
Authority is typically defined in the quality management system and may involve quality personnel, engineering, or a material review board, depending on the significance of the nonconformity and the industry.
A material review board, or MRB, is a cross-functional group, often including quality, engineering and operations representatives, authorized to evaluate and decide the disposition of nonconforming material, particularly for more complex or higher-risk items.
Organizations use containment practices such as physical segregation, quarantine areas, and clear tagging or labeling to prevent nonconforming product from being unintentionally used or delivered before a disposition decision is made.
No. Organizations typically use severity, recurrence and risk to determine whether an issue can be dispositioned and closed within the nonconformance process or whether it should be escalated to a formal corrective action investigation.
