What this grouping is not

An observation-type page groups FDA’s published citation records. The grouping, the compliance steps and the root causes are SPEQ synthesis, not an FDA classification of any citation, and a count measures what FDA published rather than risk.

What this observation means, and how to comply

SPEQ's practitioner reading of this finding. The regulatory basis is a cited fact; the interpretation, compliance steps, and root causes are SPEQ synthesis — not an FDA classification of the citation.

21 CFR 820.90

The firm lacked adequate procedures to control product that does not conform to specified requirements — to identify, document, evaluate, segregate, and disposition it, and to define who has authority to review and decide the disposition.

Why FDA writes it — Nonconforming product is where quality decisions get made under pressure. Without a controlled process, defective units get used-as-is or reworked without justification, and the same nonconformance recurs because it was never evaluated for a broader problem.

HOW TO COMPLY
  • Establish procedures to identify, document, evaluate, segregate, and disposition nonconforming product, and define the responsibility for review and the authority for disposition.
  • Document the rationale for any use-as-is or accept-by-concession decision, including the evaluation that supports it.
  • Control and document rework, including re-testing and re-evaluation to show the reworked product still meets requirements.
  • Feed nonconformance evaluations into CAPA when they indicate a systemic cause, not just a one-off defect.
WHY FIRMS GET CITED
  • Disposition authority undefined, so borderline product is released by whoever is under schedule pressure.
  • Rework performed without re-evaluation, quietly reintroducing the same risk the nonconformance flagged.
