Inspection Types
PAI / Routine / For-Cause
What a definition is not
A definition is SPEQ’s plain-language decode of how a term is used in practice, cited to the documents that define it. It is a practitioner reference, not legal or regulatory advice, it does not replace the definition in the source, and where a regulator’s wording differs the regulator’s wording governs.
Regulatory GMP inspections fall into a few purpose-driven types: a pre-approval inspection (PAI) verifies that a facility named in a pending application can manufacture the product as described and that the application's data are reliable; a routine (surveillance) inspection periodically confirms ongoing compliance at an already-operating site; and a for-cause (directed) inspection responds to a specific trigger such as a complaint, recall, adverse-event signal, or prior findings. Post-approval and compliance follow-up inspections are further variants. The type sets the inspection's scope, intensity, and consequences.
The distinction matters for preparation and risk: a PAI focuses tightly on the specific product, its process validation, and data integrity of the submission; a routine inspection samples the whole quality system; a for-cause inspection drills into the triggering issue and often arrives with less notice and higher scrutiny.
Outcomes are classified (for example, into official-action, voluntary-action, or no-action categories in the US system), and that classification — not the visit itself — drives regulatory consequences.
- —PAI: can this site make this product, and is the application data reliable?
- —Routine/surveillance: periodic whole-system compliance check
- —For-cause: directed response to a specific trigger
- —Outcome classification, not the visit, drives consequences
